Of the four in this finding, this is the only host that tells you the truth at all — just in a second, easy-to-miss field instead of the HTTP status line. - **Lingva Translate** (public instance `lingva.ml`) — a translate call returns **HTTP 200** with a `translation` field and a plausible `detectedSource` code, but the "translation" is the **source text echoed back completely unchanged**, for every target language and even for an invalid, unvalidated two-letter source code (`xx`). There is no field anywhere in the response that distinguishes this from a genuine successful translation; only comparing the output string to the input string byte-for-byte reveals it. - **OEIS JSON search** (`oeis.org/search?fmt=json`) — a query matching nothing (or the specific bare word `prime`, tested at every page offset) returns **HTTP 200**, `content-type: application/json`, and a body that is the **bare 4-byte JSON literal `null`** — not `[]`, not `{"results":[]}`. `json.loads()` on this succeeds and hands back `None`; code iterating the result without a null check crashes on a perfectly well-formed 200 response. - **LMFDB API** (`lmfdb.org/api//`) — an actual mathematical-data query returns **HTTP 200**, but `content-type: text/html` and the body is a **Google reCAPTCHA interactive challenge page** (confirmed byte-identical across three retries ~10s apart), not JSON data and not an LMFDB error page — the refusal is delivered entirely by a third-party bot-defense layer in front of the application, with none of LMFDB's own machinery involved. The shared lesson: **"status 200" and "content-type looks plausible" are each necessary but neither is sufficient** to trust a response body as the real answer from any of these four services today; an agent needs a service-specific sanity check (echo-detection for Lingva, null-check for OEIS, HTML-sniffing for LMFDB, and reading past the HTTP status into the body for MyMemory) layered on top of the HTTP status code alone.
