The Polygon.io Crypto API provides REST endpoints that let you query the latest market data for cryptocurrency pairs including trades and quotes, level 2 data, custom aggregate bars, and more.
Pass your API key in the query string like follows:
Alternatively, you can add an Authorization header to the request with your API Key as the token in the following form:
Many of Polygon.io's REST endpoints allow you to extend query parameters with inequalities like date.lt=2023-01-01 (less than) and date.gte=2023-01-01 (greater than or equal to) to search ranges of values. You can also use the field name without any extension to query for exact equality. Fields that support extensions will have an "Additional filter parameters" dropdown beneath them in the docs that detail the supported extensions for that parameter.
By default, all endpoints return a JSON response. Users with currencies Starter plan and above can request a CSV response by including 'Accept': 'text/csv' as a request parameter.
Get aggregate bars for a cryptocurrency pair over a given date range in custom time window sizes.
For example, if timespan = ‘minute’ and multiplier = ‘5’ then 5-minute bars will be returned.
The ticker symbol of the currency pair.
The size of the timespan multiplier.
The size of the time window.
The start of the aggregate time window. Either a date with the format YYYY-MM-DD or a millisecond timestamp.
The end of the aggregate time window. Either a date with the format YYYY-MM-DD or a millisecond timestamp.
Whether or not the results are adjusted for splits. By default, results are adjusted. Set this to false to get results that are NOT adjusted for splits.
Sort the results by timestamp.
asc
will return results in ascending order (oldest at the top),
desc
will return results in descending order (newest at the top).

The Polygon.io Crypto WebSocket API provides streaming access to the latest financial market data for cryptocurrency pairs. You can specify which channels you want to consume by sending instructions in the form of actions. Our WebSockets emit events to notify you when an event has occurred in a channel you've subscribed to.
Our WebSocket APIs are based on entitlements that control which WebSocket Clusters you can connect to and which kinds of data you can access. You can login to see examples that include your API key and are personalized to your entitlements.
With a premium Crypto plan, you will be able to use a single connection to the Crypto Cluster. If another connection attempts to connect to the Crypto Cluster simultaneously, the current connection will be disconnected. If you need more simultaneous connections to this cluster, you can contact support.
Connecting to a cluster:
On connection you will receive the following message:
[{
"ev":"status",
"status":"connected",
"message": "Connected Successfully"
}]
You must authenticate before you can make any other requests.
On successful authentication you will receive the following message:
[{
"ev":"status",
"status":"auth_success",
"message": "authenticated"
}]
Once authenticated, you can request a stream. You can request multiple streams in the same request.
You can also request multiple streams from the same cluster.
Things happen very quickly in the world of finance, which means a Polygon.io WebSocket client must be able to handle many incoming messages per second. Due to the nature of the WebSocket protocol, if a client is slow to consume messages from the server, Polygon.io's server must buffer messages and send them only as fast as the client can consume them. To help prevent the message buffer from getting too long, Polygon.io may send more than one JSON object in a single WebSocket message. We accomplish this by wrapping all messages in a JSON array, and adding more objects to the array if the message buffer is getting longer. For example, consider a WebSocket message with a single trade event in it:
[
{"ev":"T","sym":"XT.X:BTC-USD","i":"50578","x":4,"p":215.9721,"s":100,"t":1611082428813,"z":3}
]
If your client is consuming a bit slow, or 2+ events happened in very short succession, you may receive a single WebSocket message with more than one event inside it, like this:
[
{"ev":"T","sym":"XT.X:BTC-USD","i":"50578","x":4,"p":215.9721,"s":100,"t":1611082428813,"z":3},
{"ev":"T","sym":"XT.X:ETH-USD","i":"12856","x":4,"p":215.989,"s":1,"c":[37],"t":1611082428814,"z":3}
]
Note that if a client is consuming messages too slowly for too long, Polygon.io's server-side buffer may get too large. If that happens, Polygon.io will terminate the WebSocket connection. You can check your account dashboard to see if a connection was terminated as a slow consumer. If this happens to you consistently, consider subscribing to fewer symbols or channels.
