# NatureServe Explorer API — `GET /api/data/taxon/{elementGlobalId}`

## Probe
```
curl -D - "https://explorer.natureserve.org/api/data/taxon/ELEMENT_GLOBAL.2.101363"
```

## Observed, live today

- **No API key, no Origin/Referer requirement observed** — a bare GET from `curl` returns
  `HTTP/1.1 200 200` (note: the reason phrase literally echoes the status code, `200 200`, not
  `OK`) with a 76,700-byte JSON body.
- The record returned for `ELEMENT_GLOBAL.2.101363` is real, current conservation data:
  `scientificName: "Amphispiza bilineata"`, `primaryCommonName: "Black-throated Sparrow"`,
  `roundedGRank: "G4"`, an embedded `iucn` object (`iucnCode: "LC"`, "Least concern"), and a
  `classificationLevel` of "Species" — every text field duplicated three ways
  (`*DescEn`/`*DescEs`/`*DescFr`), i.e. the API is trilingual by field suffix rather than by an
  `Accept-Language`/locale query parameter.
- **Header/body mismatch**: `Content-Type: application/json;charset=UTF-8` is correct, but the
  same response also sends `Content-Disposition: inline;filename=f.txt` — a generic,
  meaningless filename hint that contradicts the declared JSON type. A client that honors
  `Content-Disposition` for a "Save As" filename would save valid JSON under a `.txt` name.
- `Server: Apache/2.4.68 (Win64) OpenSSL/3.6.4 mod_qos/11.79` — the stack is a **Windows-hosted
  Apache** with `mod_qos` (a request-rate/concurrency-control module) loaded, visible directly
  in the banner rather than inferred from behavior.
- `Vary: Origin,Access-Control-Request-Method,Access-Control-Request-Headers` is sent even
  though no `Origin` header was sent in this request — full CORS preflight-related `Vary`
  machinery is always present, not conditional on it being a CORS request.
- `Transfer-Encoding: chunked` is used instead of `Content-Length` for this 76,700-byte body —
  an agent trying to pre-size a download buffer from headers alone (as is possible on the
  NatureServe-adjacent CITES refusal recorded separately, which does send `Content-Length`)
  gets nothing to go on here; the size is only knowable after the full chunked body arrives.
- The id in the URL path (`ELEMENT_GLOBAL.2.101363`) is NatureServe's own stable taxon
  identifier scheme (`ELEMENT_GLOBAL.<version>.<numeric id>`), not a scientific name or a
  common taxonomic code (no ITIS TSN, no GBIF key) — `relatedItisNames` and `elcode` appear as
  separate fields inside the body for cross-referencing to those other systems, confirming the
  numeric id itself is NatureServe-internal and not reusable against ITIS or GBIF directly.

## How observed
