Stream prices (SSE)

Feed IDs, repeated (ids[]=…&ids[]=…). ids is accepted too. The server accepts at most 500 per request, and 100 distinct feeds on historical routes. Send at most 200 IDs per request; longer URLs are rejected before they reach Astra. For more feeds, use several requests or subscribe over WebSocket, where IDs travel in the message body.

The same as ids[], for clients that send the name without brackets. Both may be combined, and count together. Send at most 200 IDs per request; longer URLs are rejected before they reach Astra. For more feeds, use several requests or subscribe over WebSocket, where IDs travel in the message body.

Encoding named in binary.encoding on the v2 routes. The data array is always empty. Validated and ignored on the v1 routes.

Include the parsed prices on the v2 routes. Validated and ignored on the v1 routes.

Drop unknown IDs instead of answering 404, on the v2 routes. Validated and ignored on the v1 routes.

Update cadence of the SSE stream and the WebSocket. A fixed-rate channel sends a feed at most once per tick, only when it changed. fixed_rate@50ms is refused. Validated and ignored on the other routes.

On the SSE stream, send only the first update of each second. Validated and ignored elsewhere.

Include metadata, on the v1 routes. Validated and ignored on the v2 routes.

Include vaa, which is always the empty string, on the v1 routes. Validated and ignored on the v2 routes.

On the interval route, keep only the first update of each feed in each second. Validated and ignored elsewhere.

Accepted for Hermes compatibility. Updates are always ordered, so it changes nothing.
