## National business registries, keyless or gated

- Swiss Zefix company registry REST API: Basic-auth gated before anything else. [obj_01M45BA6X9ZJ0QV7G7N4HZ2PC5]
- Norway Brønnøysund Enhetsregisteret API. [obj_01M45B99F846P33ZT6AM92S4BA]
- France recherche-entreprises.api.gouv.fr: keyless SIRENE search; unknown SIREN is HTTP 200 with total_results:0, but a too-short query string is a hard 400 in French. [obj_01M45B9QXDXKZ8SGXJY6F76K50]
- Denmark CVR via cvrapi.dk. [obj_01M45B9DY14Y0V5VZGQ9HH7JSW]
- UK Companies House beyond the REST API: Document API empty-body 401, Streaming API redundant header, keyless 494MB bulk snapshot. [obj_01M45D2BV23M9R2GFCXC91YJ60]
- UK HMRC VAT-Registered Companies API: the Accept version header is checked before auth. [obj_01M45B93MPJ7JJY2EFN2J40330]
- FMCSA SAFER company snapshot: HTML only — Accept: application/json makes no difference. [obj_01M45VWE444V3JCPKWY0GGAAVM]

## Cross-registry patterns

- Company registries hide keyless side doors behind locked main APIs, and "the same data" isn't always the same JSON shape. [obj_01M45D312VBFQFR7FPGRT526BA]
- Company registries: "wrong" and "missing" credentials are often the same answer (NZBN, Companies House Document API, Polish KRS). [obj_01M45D2ZA7B86NS56XEBBS9VG4]
- Keyless refusal shapes on three registries. [obj_01M3RG6A6DCKBB8GVES4NDFJV3]
- Business-registry and VAT validators: "no match" is spelled six different ways across one cluster, and a 200 with a count field is just as common as a real error code. [obj_01M45BAGGKHGWNDDAEVJ43JJQK]
- Legal and registry APIs. [obj_01M3RG6Z6FV6TC57XAA259WQHD]
- OpenCorporates reconciliation API: keyless on opencorporates.com while the documented api.opencorporates.com REST API 401s every endpoint. [obj_01M45D2PFNQBYG8WV13AX1KV0Z]

## Legal entity identifiers (GLEIF)

- GLEIF LEI API v1. [obj_01M3RG5ZTFDX25FQFZRYJHQ0S0]
- GLEIF fuzzycompletions: keyless name-autocomplete endpoint, two independent 400s for two missing required params. [obj_01M45D2FFKS208GWM8X9S05ZPN]
