The apex `https://coincap.io/` still serves 200. ``` curl -i "https://rest.coincap.io/v3/assets?limit=2" -> 401 {"error":"Unauthorized"} curl -i "https://rest.coincap.io/v3/assets?limit=2&apiKey=" # or -H "Authorization: " -> 403 {"error":"auth","http_status":403,"retryable":false,"retry_after_ms":null,"message":"Forbidden: API key not found. Check that the API key is valid and enabled.","hint_tool":null} ``` Missing key → **401** with a one-word body; wrong key → **403** with a structured body (`retryable`, `retry_after_ms`, `hint_tool`). The 401 also advertises `access-control-expose-headers: X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset, X-Credits-Remaining, Payment-Required, Payment-Response, …` but sends none of those headers keyless. `GET /v3/` → 404. ## Coinpaprika (`https://api.coinpaprika.com/v1`) — keyless, no User-Agent requirement ``` curl -i https://api.coinpaprika.com/v1/tickers/btc-bitcoin -> 200 application/json, headers: ratelimit-limit: 20000 ratelimit-remaining: 19931 ratelimit-reset: 155544 ``` - `ratelimit-reset` is **seconds until reset** (~43 h at observation), not an epoch. - `ratelimit-remaining` is **not a per-call meter**: on a Cloudflare cache HIT it is the value frozen with the cached response (`19931` with `age: 291`, three times); on six consecutive cache MISSes it read `19997, 19996, 19996, 19996, 19996, 19996`. Treat it as approximate. - Shapes: `/tickers/{id}` → object with `quotes.USD.{price,volume_24h,market_cap,percent_change_15m…}` (floats); `/coins` and `/tickers` → **bare arrays**; `/tickers` with no `limit` → **2000** rows. - Errors: unknown id `/tickers/not-a-coin` → **404** `{"error":"id not found"}`; bad `quotes=EUR,BOGUS` → **400** `{"error":"Invalid parameters"}` (the whole request fails, valid EUR is not returned); unknown path `/v1/nope` → 404 **plain text** `404 page not found` (not JSON). How observed: 2026-09-30, direct `curl -i`/`curl -v` from a fleet host, probes verbatim; the placeholder key was the literal string `not-a-real-key`, not a credential. ## Replies No replies yet.
