IEX Cloud API Reference

IEX Cloud is a platform that makes financial data and services accessible to everyone.

The IEX Cloud API is based on REST, has resource-oriented URLs, returns JSON-encoded responses, and returns standard HTTP response codes.

• The base url for the API is: https://cloud.iexapis.com/
• We support JSONP for all endpoints.

API Versioning

IEX Cloud will release new versions of the API when we make backwards-incompatible changes. We plan to support up to three active versions and will give advanced notice before releasing a new version or retiring an old version.

Backwards compatible changes:

• Adding new response attributes
• Adding new endpoints
• Adding new methods to an existing endpoint
• Adding new query string parameters
• Adding new path parameters
• Adding new webhook events
• Adding new streaming endpoints
• Changing the order of existing response attributes

Current Version is v1

Naming Convention

stable can be used to access the latest stable API version. beta can be used to access the latest API version.

Endpoint Versioning

Endpoints may be in various states of alpha, beta, deprecated, etc. These indicate that an endpoint is either not yet subject to the requirements above (in the case of alpha, beta) or that it will be modified within the same API version (in the case of deprecated).

Deprecation

Both the IEX Cloud platform and the financial data ecosystem are constantly evolving, so it may become necessary to deprecate or disable some endpoints without versioning the entire API. Some situations which might require this action include changes to data contracts, critical useability issues, data universe expansion, etc. In these situations we will make every effort to provide alternative access to the underlying data or another provider’s data, and maintain the deprecated endpoints for a reasonable timeframe.

An endpoint will be removed ~6 Months from the time of deprecation with advance notice given via email and any alternative functionality available in both the API and official client libraries.

Attribution

Attribution is required for all users. It is as simple as putting “Data provided by IEX Cloud” somewhere on your site or app and linking that text to https://iexcloud.io. In case of limited screen space, or design constraints, the attribution link can be included in your terms of service.

<a href="https://iexcloud.io">Data provided by IEX Cloud</a>

When displaying a real-time price, you must display and link to IEX Cloud as the source near the price. The link is commonly placed below the price.

How Credits Work (Legacy)

Credit Basics

Every dataset has an associated cost in credits based on:

• How much data is there? A dataset like Fundamentals includes hundreds of fields, while a single US Treasury Yield record might only have one field.
• How frequently does the data update? Quote updates millions of times per day, while Unemployment Rate might only update weekly
• How much does it cost to acquire the data? Some datasets we collect on our own, other datasets we purchase from upstream vendors. Ingesting and normalizing data has infrastructural costs on top of the base dataset cost.
• How much does it cost to distribute the data? With billions of API calls and bursty workloads around market hours, our infrastructure needs to scale up and down to ensure constant uptime and consistent delivery.

We call this associated credit cost the dataset’s weight. When you access a dataset, the total weight charged for the access will generally be the weight multiplied by the number of records received (taking into account the other possible credits or debits below). If you don’t receive any records, you won’t be charged for accessing that dataset. Each endpoint has its own weight which you can find in the documentation below. If the sum of these charges exceeds your monthly credit allocation, you will need to upgrade or purchase additional packages to continue accessing data.

Credit allocations reset on the first of each month at 00:00:00 UTC. API calls will return iexcloud-credits-used in the header to indicate the total number of credits consumed for the call, as well as an iexcloud-premium-credits-used to indicate the total number of premium credits consumed for the call. You can also track this information in the console.

Other credits and debits

API Use

All API calls will have an additional 1 credit access charge. This allows us to keep data costs lower across a wide variety of datasets. The following endpoints are omitted:

• Account endpoints
• Status endpoints
• Rules endpoints
• Timeseries Metadata and Inventory endpoints
• Files inventory endpoints
• Data points inventory endpoints
• Calls that result in 4XX or 5XX error codes

SSE connections will have a 1 credit charge on initial connection, not per record. Batch calls will have an additional 1 credit charge for the entire batch, regardless of the number of symbols or channels contained in the batch.

Cloud Cache

If you have an account in the individual or business tiers (rather than a legacy launch, grow, or scale account or a free start account), and you query the same API for data which has not changed, your cost will be reduced to 1 credit per record thanks to Cloud Cache.

As an example, lets say I access Cash Flow data for AAPL. It is the first time I have accessed it this month, and I only access the most recent record, so I am charged 1,000 credits. If I access this same API again this month, and it has not changed, I will only be charged 1 credit as the access has been cached. With Cloud Cache, you only pay for the new data you receive.

Reducing your credit spend

There are several strategies to reduce your costs when accessing datasets.

First, when developing be sure to experiment against the sandbox. Sandbox expenditures do not count against your monthly limit.

Second, decide on an appropriate history and update interval. For example, if I want to access 5 years of financial statements, I do not need to purchase a plan that allows me to access 5 years of financial statements each month. I can simply purchase enough packages to backfill 5 years once, then reduce my packages to maintain ongoing updates. You can also leverage APIs like data points to check when data has been updated.

Authentication

API Tokens

IEX Cloud authenticates your API requests using your account’s API tokens. To use any IEX Cloud API, you must pass an API token with each request. If you do not include your API token when making an API request, or use one that is incorrect or disabled, IEX Cloud returns an error.

IEX Cloud provides two types of API tokens: publishable and secret.

• Publishable API tokens are meant solely to identify your account with IEX Cloud, they aren’t secret. They can be published in places like your website JavaScript code, or in an iPhone or Android app.

• Secret API tokens should be kept confidential and only stored on your own servers. Your account’s secret API token can perform any API request to IEX Cloud.

Protecting Your API Tokens

• Keep your secret token safe. Your secret token can make any API call on behalf of your account, including changes that may impact billing such as enabling pay-as-you-go charges. Do not store your secret token in your version control system. Do not use your secret token outside your web server, such as a browser, mobile app, or distributed file.
• Monitor usage of your API for anomalies. If you observe unauthorized or abnormal usage, rotate your API token. IEX Cloud provides multiple options to address abnormal usage. ..* You may use the IEX Cloud console to rotate an API token. Rotating a token will disable access to IEX Cloud for the rotated token within 10 seconds. ..* You may use the IEX Cloud API or console to disable pay-as-you-go. This may prevent unexpected charges due to unauthorized or abnormal usage.
• Do not embed API keys directly in code. Instead of directly embedding API keys in your application’s code, put them in environment variables or in include files that are stored separately from the bulk of your code—outside the source repository of your application. Then, if you share your code, the API keys will not be included in the shared files.
• Do not store API tokens in inside your application’s source control. If you store API tokens in files, keep the files outside your application’s source control system. This is particularly important if you use a public source code management system such as GitHub.
• Limit access with restricted tokens. IEX Cloud console will allow you to specify the IP addresses or referrer URLs associated with each token, reducing the impact of a compromised API token.
• Use independent API tokens for different apps. This limits the scope of each token. If an API token is compromised, you can rotate the impacted token without impacting other API tokens.

Error Codes

IEX Cloud uses HTTP response codes to indicate the success or failure of an API request.

General HTML status codes

2xx Success.

4xx Errors based on information provided in the request

5xx Errors on IEX Cloud servers

IEX Cloud HTTP Status Codes

Security

We provide a valid, signed certificate for our API methods. Be sure your connection library supports HTTPS with the SNI extension.

Request Limits

IEX Cloud only applies request limits per IP address to ensure system stability. We limit requests to 100 per second per IP measured in milliseconds, so no more than 1 request per 10 milliseconds. We do allow bursts, but this should be sufficient for almost all use cases. Note that Sandbox Testing has a request limit of 10 requests per second measured in milliseconds.

SSE endpoints are limited to 50 symbols per connection. You can make multiple connections if you need to consume more than 50 symbols.

Guides

REST How-To

Making your first REST API call is easy and can be done from your browser.

You will need:

• Your publishable token which is found in the Console.
• The URL for the type of data you would like to request.

REST calls are made up of:

• Base url. Example: https://cloud.iexapis.com
• Version. Example: beta
• Token. All REST requests require a valid token and can be added to a url like ?token=YOUR_TOKEN_HERE

Excel How-To

IEX Cloud supports Excel and Google Sheets data import methods.

Excel

Excel provides the Webservice function to import data into a cell. We support this functions in the /stock/{symbol}/quote and /stock/{symbol}/stats endpoints, and in the Balance Sheet, Cash Flow, Dividends, Financials, and Income core dataset endpoints:

Example: Pull latest price for Apple

=WEBSERVICE("https://cloud.iexapis.com/v1/stock/aapl/quote/latestPrice?token=YOUR_TOKEN_HERE")

IEX Cloud provides an example Excel file that can be used to see how the web service function works.

Download it here - the Excel webservice function only works on Excel for Windows.

Please note, the highlighted column for latestUpdate is a formula that converts the Unix timestamp into an Excel date/time. To get this to work you must enter your token in column B1. And make sure to refresh your workbook (CTRL + ALT + F9).

Google Sheets

Google Sheets provides IMPORT functions to populate cells with data.

Example: Pull latest price for Apple

=IMPORTDATA("https://cloud.iexapis.com/v1/stock/aapl/quote/latestPrice?token=YOUR_TOKEN_HERE")

Example: Next earnings report date for Apple

=IMPORTDATA("https://cloud.iexapis.com/v1/stock/aapl/estimates/1/reportDate?token=YOUR_TOKEN_HERE")

CSV Files

You can also return most endpoints in CSV format by using the query parameter format=csv.

Testing Sandbox ^Deprecated

IEX Cloud provides all accounts a free, unlimited use sandbox for testing. Every account will be assigned two test tokens available via the Console. All sandbox endpoints function the same as production, so you will only need to change the base url and token.

We’ve also updated the Usage Report to allow you to view the number of test credits the same way as production credit usage.

How to Use

• The base url is https://sandbox.iexapis.com
• You can also test SSE with https://sandbox-sse.iexapis.com
• Your test token is available on the console by click the “View Test Data” toggle in the nav.
• All tier features are enforced at this time, but you are not limited by the number of calls you can make. You are not charged for test usage.

Test tokens look like Tpk_ and Tsk_

To make a call for test data, use the same url, but pass your test token.

API Usage

Common functionality across all APIs.

Query Parameters

• Parameter values must be comma-delimited when requesting multiple.
  • (e.g., symbols=SNAP,fb is correct.)
• Case does not matter when passing values to a parameter unless specified in the docs.
  • (e.g., Both symbols=fb and symbols=FB work.)
• Make sure to URL-encode values.
  • (e.g., symbols=AIG+ encoded is symbols=AIG%2b.)

Data Formats

Some endpoints support a format parameter to return data in a format other than the default JSON.

Supported formats

Filter Results

Some endpoints support a filter parameter to return a subset of data. Pass a comma-delimited list of response attributes to filter. Response attributes are case-sensitive and are listed in each endpoint reference document’s Response Attributes section.

Example: filter=symbol,volume,lastSalePrice returns only these three specified attributes.

Result Schema

In many cases, you may want to know the type of returned data. For example, you want to build a SQL table from endpoint results and you want to know/verify column types.

Some endpoints support a schema parameter to return just the types of the result set. Simply pass in the schema=true query parameter and the endpoint returns an array of column names and data types from a resulting data record.

Time Series

Time Series Endpoint

Time series is the most common type of data available, and consists of a collection of data points over a period of time. Time series data is indexed by a single date field, and can be retrieved by any portion of time.

To use this endpoint, you’ll first make a free call to get an inventory of available time series data.

HTTP REQUEST

# List all available time series data
GET /time-series

RESPONSE

{
  "id": "REPORTED_FINANCIALS",
  "description": "Reported financials",
  "key": "a valid symbol",

  "lastUpdated": "2019-06-04 21:32:20"
}

A full inventory of time series data is returned by calling /time-series without a data id. The data structure returned is an array of available data sets that includes the data set id, a description of the data set, the data weight, a data schema, date created, and last updated date. The schema defines the minimum data properties for the data set, but note that additional properties can be returned. This is possible when data varies between keys of a given data set.

Each inventory entry may include a key and subkey which describes what can be used for the key or subkey parameter.

Once you find the data set you want, use the id to query the time series data.

HTTP REQUEST

# Get time series data
GET /time-series/{id}/{key?}/{subkey?}

Time series data is queried by a required data set id. For example, “REPORTED_FINANCIALS”. Some time series data sets are broken down further by a data set key. This may commonly be a symbol. For example, REPORTED_FINANCIALS accepts a symbol such as AAPL as a key. Data sets can be even further broken down by sub key. For example, REPORTED_FINANCIALS data set with the key AAPL can have a sub key of 10-Q or 10-K.

Keys and sub keys will be defined in the data set inventory.

Time series call returns an array of objects. The data returned varies by dataset ID, but each will contain common attributes.

Time series inventory call returns:

Time Series Metadata ^BETA

Time-Series presents us a with a powerful query interface on top of our data, while the inventory calls allow us to know the shape of the data contained therein. But sometimes we want to answer questions like “What are all the possible values of key for the time series id FUNDAMENTALS?” or “What time series ids contain data on AAPL?”

For these, we have time series metadata.

HTTP REQUEST

GET /metadata/time-series/{id}/{key?}/{subkey?}

RESPONSE

// metadata/time-series
[
  {
    "id":"ADVANCED_BONUS",
    "value":"ADVANCED_BONUS",

Points and Files

Data Points let you access individual data values, while Files lets you conveniently access pregenerated files.

Data Points

Data points are available per symbol and return individual plain text values. Retrieving individual data points is useful for Excel and Google Sheet users, and applications where a single, lightweight value is needed. Some endpoints provide update times; this allows you to call an endpoint only once it has new data.

To use this endpoint, first make a free call to list all available data points for your desired symbol, which can be a security or data category.

HTTP REQUEST

# List available data keys
GET /data-points/{symbol}

RESPONSE

[
    {
        "key": "BETA",
        "weight": 1,
        "description": "",
        "lastUpdated": "2022-07-29T09:46:08+00:00"
    },
    {
        "key": "ACCOUNTSPAYABLE",
        "weight": 3000,
        "description": "Balance Sheet: accountsPayable",
        "lastUpdated": "2022-05-09T12:47:55+00:00"

Streaming Data

SSE Streaming

NOTE: Only included with paid subscription plans

We support Server-sent Events (SSE Streaming) for streaming data as an alternative to WebSockets. You will need to decide whether SSE streaming is more efficient for your workflow than REST calls. In many cases streaming is more efficient since you will only receive the latest available data. If you need to control how often you receive updates, then you may use REST to set a timed interval.

Snapshots

When you connect to an SSE endpoint, you should receive a snapshot of the latest message, then updates as they are available. You can disable this feature by passing a url parameter of nosnapshot=true.

You can also specify a starting point for a snapshot by passing a url parameter of snapshotAsOf=EPOCH_TIMESTAMP where the value is in milliseconds since Epoch.

Curl Example

curl --header 'Accept: text/event-stream' https://cloud-sse.iexapis.com/stable/stocksUS\?symbols\=spy\&token\=YOUR_TOKEN

Curl Firehose Example

curl --header 'Accept: text/event-stream' https://cloud-sse.iexapis.com/stable/stocksUS\?token\=YOUR_TOKEN

Curl Example (Not authorized by UTP)

curl --header 'Accept: text/event-stream' https://cloud-sse.iexapis.com/stable/stocksUSNoUTP\?symbols\=spy\&token\=YOUR_TOKEN

Curl Firehose Example (Not authorized by UTP)

curl --header 'Accept: text/event-stream' https://cloud-sse.iexapis.com/stable/stocksUSNoUTP\?token\=YOUR_TOKEN

How Credits Are Counted

We use a reserve system for streaming endpoints due to high data rates. This is similar to how a credit card puts a hold on an account and reconciles the amount at a later time.

When you connect to an SSE endpoint, we will validate your API token, then attempt to reserve an amount of credits from your account. For example, 1000 credits.

If you have enough credits in your quota (if you have pay-as-you-go enabled on our legacy plans), we will allow data to start streaming.

We keep track of the number of messages streamed to your account during our reserve interval.

Once our reserve interval expires, we will reconcile usage. This means we will compare how many credits worth of messages were sent versus the number of credits we reserved. For example, if we delivered 1200 credits worth of messages, you would have used 200 more than we reserved, so we will apply 200 additional credits to your account. If we only delivered 100 credits worth of messages, we would add the 900 unused credits back to your account.

After we reconcile the credits, we will attempt another reserve.

The reserve and reconcile process is seamless and does not impact your data stream. If we attempt to reserve credits and your account does not have enough quota (and pay-as-you-go disabled on legacy accounts), then we will disconnect your connection. You can avoid service disruptions by ensuring you have sufficient credits, either by purchasing additional packages or, on legacy plans, by enabling pay-as-you-go.

When you disconnect from an endpoint, we will reconcile your credit usage immediately.

Firehose

Scale and Business plan users can firehose stream all symbols (excluding DEEP endpoints) by leaving off the symbols parameter.

Interval Streaming

Some SSE endpoints are offered on set intervals such as 1 second, 5 seconds, or 1 minute. This means we will send out messages no more than the interval subscribed to. This helps make message delivery more predictable.

Rules Engine ^BETA

Rules Engine API

Evaluate thousands of data points per second and build event-driven, automated alerts using Rules Engine. You can access Rules Engine through the IEX Console or through our API using the guidelines below.

Your Secret API Token (sk_) should be used to interact with Rules Engine API endpoints. Make sure to not expose your secret token publicly. All interactions should be from a secure server. Find and manage your API Tokens through the console.

To create a rule:

• Call /rules/schema to understand what values can be used to create the rule
• Call /rules/create to create a rule
• Call /rules/info to check the status of your newly created rule

Rules Schema

Pull the latest schema for data points, notification types, and operators used to construct rules.

HTTP REQUEST

GET /stable/rules/schema

Signed Requests

Making your first Signed REST API requires a little more effort. This approach has been heavily based on Amazon’s V4 signing approach. The basic idea is to take your secret key, and use that to generate a cryptographic fingerprint of all aspects of your request, so they can be verified by the server, so the interception of the data over the network does not compromise your account. However, you must take care that your secret key for your publishable key is not compromised!

You will need:

• Your publishable token which is found in the console
• Your secret key for your publishable token, can be found below using the GET /account/signed API call
• The URL for the type of data you would like to request

Signed REST calls are made up of:

• Base url. Example: https://cloud.iexapis.com
• Version. Example: beta
• Token. All REST requests require a valid token and can be added to a url like ?token=YOUR_TOKEN_HERE
• The authorization header
• The x-iex-date header

Setting Up Signed Token

Signs a token, so it will require signed headers when a request is made using this token.

HTTP REQUEST

POST content-type:application/json { "token" : "SK_TOKEN", "tokenToSign" : "PK/SK_TOKEN_TO_BE_SIGNED", ("unsign" : true) } /account/signed

RESPONSE

{
  "secret" : "e2700e6b-3be0-4f31-a408-61365caa263a",
  "signedToken" : "pk_6b95e1fac3114f0392a5becd4d8f08e1"
