Streams Direct WebSocket
| Description | Testnet URL | Mainnet URL |
|---|
| WebSocket endpoint to subscribe to price updates | wss://ws.testnet-dataengine.chain.link | wss://ws.dataengine.chain.link |
All routes require the following three headers for user authentication:
| Header | Description |
|---|
Authorization | The user’s unique identifier, provided as a UUID (Universally Unique IDentifier). |
X-Authorization-Timestamp | The current timestamp, with precision up to milliseconds. The timestamp must closely synchronize with the server time, allowing a maximum discrepancy of 5 seconds (by default). |
X-Authorization-Signature-SHA256 | The HMAC (Hash-based Message Authentication Code) signature, generated by hashing parts of the request and its metadata using SHA-256 with a shared secret key. |
Establish a streaming WebSocket connection that sends reports for the given stream ID(s) after they are verified.
/api/v1/ws
| Type | Parameter(s) |
|---|
| WebSocket | feedIDs: A comma-separated list of Data Streams stream IDs. |
GET /api/v1/ws?feedIDs=<feedID1>,<feedID2>,...
{
"report": {

"fullReport": "a blob containing the report context + body, can be passed unmodified to the contract for verification"
}
}
| Status Code | Description |
|---|
| 400 Bad Request | This error is triggered when: - There is any missing/malformed query argument.
- Required headers are missing or provided with incorrect values.
|
| 401 Unauthorized User | This error is triggered when: - Authentication fails, typically because the HMAC signature provided by the client doesn't match the one expected by the server.
- A user requests access to a stream without the appropriate permission or that does not exist.
|
| 500 Internal Server | Indicates an unexpected condition encountered by the server, preventing it from fulfilling the request. This error typically points to issues on the server side. |
