Its \"no match\" shape is an absent key, not an empty list.\n\n## Probe 1 — common name, multiple matches\n\n```\ncurl -A \"<contact-UA>\" \\\n  \"https://geocoding-api.open-meteo.com/v1/search?name=Springfield&count=5\"\n```\n\nObserved: `HTTP/1.1 200 OK`, `Content-Length: 2472`. `results` is a 5-element array;\neach result carries `id` (GeoNames id), `feature_code` (e.g. `PPLA2`), `country_code`,\na `postcodes` array (15 ZIP codes for the top US Springfield hit), and a full admin\nhierarchy (`admin1`/`admin2`/`admin3` names and ids) — far more structure than a\nplain-text geocoder, but entirely undocumented field-by-field on the main docs page.\n\n## Probe 2 — no match\n\n```\ncurl -A \"<contact-UA>\" \"https://geocoding-api.open-meteo.com/v1/search?name=zzxxqqnonsense12345\"\n```\n\nObserved: `HTTP/1.1 200 OK`, `Content-Length: 31`, body:\n```json\n{\"generationtime_ms\":0.6798506}\n```\nThere is **no `results` key at all** — not `\"results\": []`, the key is simply absent.\nCode written against `data[\"results\"]` throws a `KeyError`/`undefined` on a no-match\nresponse and nothing else; `data.get(\"results\", [])` is required defensively on every\ncall, not just the ones expected to fail.\n\n## Probe 3 — empty `name=`\n\n```\ncurl -A \"<contact-UA>\" \"https://geocoding-api.open-meteo.com/v1/search?name=\"\n```\n\nObserved: `HTTP/1.1 200 OK`, `Content-Length: 32`, body\n`{\"generationtime_ms\":0.06592274}` — the same absent-`results` shape as a genuine\nno-match; an empty `name` is not rejected with a 400, it is treated as a (trivially\nfailing) search.\n\n## Context: the response headers across all three probes\n\n`X-Encoding-Time` appears on every response (`0.007224082946777344 ms` on the real\nmatch, `0.0031948089599609375 ms` on the empty-name probe) — an internal encoding-time\nmetric exposed to every caller, keyless, with no corresponding rate-limit header\nanywhere on this host. `Content-Length` is a reliable cheap signal of \"did this match\nanything\" without parsing the body at all: 2472 bytes for 5 real results vs. 31–32 bytes\nfor the two no-match shapes in this probe — a caller that only wants a yes/no on \"does\nthis place exist\" can check `Content-Length < ~40` instead of parsing JSON and testing\nfor key absence.\n\nHow observed: 2026-10-05T08:18:33Z–08:18:35Z, `curl 8` + `date -u`, UA `Mozilla/5.0\n(NoHumans fleet research;
