The same silent-empty\n   shape also appears for any unrecognized `rettype` value with no numeric id at all.\n3. **NCBI dbSNP/Variation Services** (`refsnp/{id}`) — the universal, human-standard\n   `rs`-prefixed id format (`rs7412`, as used everywhere dbSNP ids are written) is not\n   a validated `400` but an unhandled `500` with an empty body; only the\n   undocumented bare-digit form (`7412`) is accepted, and a genuinely nonexistent bare\n   digit id correctly gets a clean `404` JSON envelope that the malformed-format case\n   never reaches.\n4. **HGNC REST** (`rest.genenames.org/fetch/{field}/...`) — an unrecognized search\n   `field` name is reported as `HTTP 200` whose body is the literal text `400 Bad\n   Request` immediately followed by a second, complete, embedded Apache `400 Bad\n   Request` HTML error page — two glued-together error documents under a success\n   status, and the `Accept: application/json` header that correctly produces JSON on\n   the happy path is ignored here (`text/plain` instead).\n5. **OMIM API** — the keyless-request refusal ignores the requested `format=json`\n   entirely and returns a `400` Apache Tomcat HTML stack-trace-style page regardless;\n   a malformed `apiKey` value is checked for exact string length (and the submitted\n   garbage value echoed back) before any real key lookup, also inside an HTML body.\n6. **EBI GWAS Catalog legacy REST** — a fully-retired API signals retirement with an\n   intermittent, mostly-blocking `429 Too Many Requests` (no `Retry-After`; roughly\n   one request in five slips through with no header explaining why) rather than the\n   `410 Gone` its own sibling summary-statistics endpoint correctly uses for the\n   identical situation — an agent's standard, correct \"back off and retry on 429\"\n   behavior gets just enough intermittent success to look like it is working, with no\n   way to know the real cause is permanent deprecation, not transient load.\n\nTwo services probed in the same lane behave the opposite way and are worth citing as\nthe contrast, not the pattern: Ensembl REST's `overlap/region` cap and UCSC's\n`getData/track` both reject bad input with a clean, specific, status-matched error on\nthe very first try. The failure mode above is common but not universal — \"assume a\nclean validated error\" is just as wrong an assumption as \"assume status==200 means\nsuccess\" in this cluster.\n\nHow observed:
