# Stream real-time prices for multiple assets (Removed)

> **Removed. Always returns `410 Gone`. Use [`POST /sse/prices`](#operation/streamBatchAssetPrices) with `method: token_price` instead.**




## OpenAPI

````yaml /streaming/api-streaming.yml post /stream
openapi: 3.1.0
info:
  title: DexPaprika Streaming API
  version: 1.0.1
  license:
    name: UNLICENSED
    identifier: UNLICENSED
  description: >
    The DexPaprika Streaming API delivers real-time updates for token prices,
    swap transactions,

    and pool reserves over Server-Sent Events (SSE).


    ## Rate Limits


    - **Concurrent SSE streams per IP:** 10. Excess returns `429` with
    `{"message": "ip stream limit exceeded"}`.

    - **Assets per `POST /sse/prices`:** 25. Excess returns `400` with
    `{"message": "too many assets, max 25 allowed"}`.

    - **Request body on `POST /sse/prices`:** 256 KB. Excess returns `413
    Payload Too Large`.

    - **Request rate (per IP x path x method):** 60 req / 60 s. Excess returns
    `429` with `{"message": "you have reached maximum request limit"}`.


    ## HTTP Response Codes


    - `200` — SSE connection established.

    - `400` — Invalid request (bad params, unknown chain, unknown asset, or
    asset cap exceeded).

    - `413` — Request body exceeds the route limit.

    - `429` — Per-IP stream limit, per-route rate limit, or global stream slot
    pool exhausted.

    - `503` — Service saturated (concurrent in-flight cap reached).


    ## SSE Event Format


    Events conform to the W3C SSE specification. Non-system events on
    multiplexed streams include

    an optional `request_id` line for correlating events to subscriptions:


    ```

    event: [event_name]

    request_id: [request_id]

    data: [json_payload]

    ```


    ## Event Types


    - `token_price` (`PriceResponse`) — Real-time price update.

    - `ping` (`PingEvent`) — Heartbeat sent every 15 s. Treat absence for >30 s
    as a potential connection problem.

    - `warning` (`WarningEvent`) — Non-fatal notice (e.g. partial subscription
    accepted).

    - `error` (`ErrorEvent`) — Terminal stream-level error sent before
    connection close.


    ## Error Message Catalog


    400 errors:

    - `at least one asset is required`

    - `invalid method`

    - `unsupported chain`

    - `asset not found`

    - `too many assets, max 25 allowed`


    429 errors:

    - `ip stream limit exceeded`

    - `Cannot create new subscriptions, global stream limit exceeded`

    - `you have reached maximum request limit`


    503 errors:

    - `Too many concurrent requests`


    ## Removed endpoints


    The legacy `/stream` path has been removed and returns `410 Gone` — use
    `/sse/prices` instead.
