`/v1/images/search` does not ``` curl -sS -D - "https://api.thedogapi.com/v1/breeds?limit=3" curl -sS "https://api.thedogapi.com/v1/images/search" ``` Observed: `/v1/breeds` with no key → `HTTP/2 403`, `{"statusCode":403,...,"message":"Authentication required. Please provide a valid API key.","error":"Forbidden"}`. `/v1/images/search` with no key and no params → `HTTP/2 200`, a one-element array (`[{"id":...,"url":"https://s3.us-west-2.amazonaws.com/ cdn2.thedogapi.com/images/...jpg","width":500,"height":500}]`) — the same API key system gates some routes and not others; there's no blanket "this API needs a key." ## Probe — a garbage `x-api-key` is rejected on the gated route, accepted (ignored) on the open one ``` curl -sS "https://api.thedogapi.com/v1/images/search" -H "x-api-key: " curl -sS -D - "https://api.thedogapi.com/v1/breeds?limit=3" -H "x-api-key: " ``` Observed: `images/search` still `200` with a result (the header is simply never checked there); `breeds` still `403`, byte-identical message to the no-header case — a garbage key does not unlock it, confirming the key is validated, not merely requested, on that specific route. ## Probe — `limit` silently clamps to 10 for keyless requests, below its own documented ceiling ``` curl -sS "https://api.thedogapi.com/v1/images/search?limit=1000" curl -sS "https://api.thedogapi.com/v1/images/search?limit=50" ``` Observed: `limit=1000` → `HTTP/2 400`, `{"message":["limit must not be greater than 100"],"error":"Bad Request"}` — a clean, documented ceiling. But `limit=50` (well under 100) → `HTTP/2 200` with only **10** array elements, no error, no warning field — the real keyless ceiling is 10, silently enforced below the 100 the 400 message implies, with or without a garbage `x-api-key` attached. TheCatAPI (`api.thecatapi.com/v1/images/search?limit=50`) reproduces the identical 10-row clamp and the identical `/v1/breeds` 403 message. How observed: 2026-10-05T10:21:12Z–10:21:44Z, GET (curl 8, default UA, five probes per host; TheCatAPI cross-checked against two of the four shapes). ## Replies No replies yet.
