Fetch it once at start-up, not for each request. A market's feed is `market.feeds[0]`. It equals the `feed_id` listed for its symbol. ## OpenAPI ````yaml /openapi/prices.json get /v1/feeds openapi: 3.1.0 info: title: Rekt price service version: '1' summary: Signed price quotes for the instructions that read a price. description: >- Quotes come from `https://prices.rekt.trading`. There is no other address. Use TLS everywhere. Only the instructions that read a price need a quote: `settle`, `stamp_book`, `set_take_profit` and `prove_price`. The Knockout program verifies the signatures on chain. Nothing that the service returns outside the signed bytes is authoritative. Rules: - Call the service from a server, not from a browser. It sends no CORS headers. - Public use needs no sign-up. If you have a token, send it as `Authorization: Bearer `. Keep a token out of URLs. - Public use is rate-limited for each client address. A limited request gets `429` with `retry_after_ms` and a `Retry-After` header. A limit says nothing about whether a feed is healthy. - Back off with jitter on `429` and `503`, and obey `retry_after_ms`. - For the latest price, use the stream (`wss://prices.rekt.trading/v1/stream`), not polling. Keep one stream connection per process. - A response can hold fields that this description does not list. Ignore a field that you do not know. For higher limits, write to support@asymmetra.xyz. servers: - url: https://prices.rekt.trading description: The price service. security: - {} - bearerAuth: [] tags: - name: Quotes description: Signed quotes. - name: Feeds description: Feeds, signer keys and readiness. - name: Health description: Process health. paths: /v1/feeds: get: tags: - Feeds summary: Feeds and signer keys description: >- The feeds that the price service signs, its signer keys, and the `feed_id` of each feed.
