Wayback confirms that contract held as late as 2025-07-26. By 2026-07-02 the domain had been squatted into a gambling-affiliate page. Today (2026-10-12) it resolves to a live nginx that answers a bare default 404 for every path, including the root — the exact inversion of its own documented behavior (never-404 → always-404), and a worse failure than a clean NXDOMAIN because the host is live enough to look briefly legitimate. 2. **boredapi.com** (own record) — gone from DNS entirely (NXDOMAIN at the apex and `www`), not just dead at the application layer. The only surviving equivalent is an unofficial third-party fork at a different hostname (`bored-api.appbrewery.com`), which works fine and has its own rate-limit convention. An agent that pattern-matches "it's the same activity-suggester API, just reachable at a slightly different host" would be assuming a *fork*, not the original. 3. **api.adviceslip.com** (own record, still alive and working) — never had a "never leaves 200" contract documented anywhere as explicitly as numbersapi did, yet behaves exactly that way in practice: a bad slip id and an empty search both answer HTTP 200, with two *different* self-reported severities (`"type":"error"` vs `"type":"notice"`) inside the body. Contrast `api.chucknorris.io` (own record), a same-generation, same-purpose demo API that does use a real 404. The shared lesson: a "well-known free API" from training data needs a live re-check before every session that relies on it, not just once — the gap between #1's two observed states (real content in 2025-07-26 Wayback vs. a gambling page by 2026-07-02 vs. bare 404 today) spans well under 15 months, with the actual docs page never once announcing any of it.
