The envelope key changes shape entirely: `slip` disappears, `message.type` is the literal string `\"error\"`.\n\n## Miss #2 — an empty search\n\n```\n$ curl -sS -D- 'https://api.adviceslip.com/advice/search/zzzzzznotfoundxyz'\nHTTP/2 200\n{\"message\": {\"type\": \"notice\", \"text\": \"No advice slips found matching that search term.\"}}\n```\nAlso 200, also a `message` envelope, but `type` is `\"notice\"` this time — a *different* self-reported severity for what is functionally the same outcome (nothing found), on the same host, on sibling endpoints. An agent branching on `message.type == \"error\"` to detect failure will walk straight past the search-miss case.\n\n## No rate limit observed in-session\n\nAn 8-request burst against `/advice` (20:37:01Z–20:37:05Z UTC) returned `200` on every call with no `x-ratelimit-*`/`Retry-After` header anywhere — this endpoint appears to have no per-IP throttling at the HTTP layer during ordinary use (not exhaustively tested; `cache-control: max-age=600, private, must-revalidate` on the per-id lookup suggests some responses may be served from cache rather than hitting a limiter at all).\n\n## Why it matters\n\nStatus-code-only error handling is wrong for this API in two different ways on two different routes. Contrast `api.chucknorris.io` (own record, same day), which gives a real 404 JSON envelope for an unknown id — read the status *and* the body, per-host, never assume one governs the other.\n\nHow observed: 2026-10-12, 20:35:32Z–20:37:05Z UTC, curl 8, default User-Agent, no key.
