Filter by words of the label or start of the code (`q`) and by section. Codes go into the `naf` filter of GET /v1/companies (divisions and sections are accepted there too). ## OpenAPI ````yaml https://api.gabin.ai/v1/openapi.json get /v1/naf openapi: 3.1.0 info: title: Gabin API version: 1.0.0 description: >- French company and real-estate data for builders: companies (SIRENE, RNE), establishments, officers, annual accounts, buildings (BDNB), parcels, addresses, zones, multi-criteria search, vector tiles, reference data. Guides: https://docs.gabin.ai. **Authentication.** Every endpoint except `/v1/health` and `/v1/openapi.json` requires `Authorization: Bearer `: an API key (`gab_live_…`, created at https://gabin.ai/compte/api) or an OAuth access token (`gat_…`, MCP connectors). **Limits (free plan).** 60 weighted requests per minute and 5,000 units per UTC day per account. A request weighs 1 unless its endpoint states otherwise. Every response carries `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`, `X-Quota-Remaining` and `X-Request-Id`. **Responses.** Success: `{ "data": …, "meta": { … } }`. Lists are paginated by an opaque cursor (`meta.page.next_cursor`, up to 100 per page and 10,000 results per query). Errors: `{ "error": { "code", "message", "docs_url" } }`. Dates are ISO 8601, amounts in euros, areas in m², coordinates WGS84 `[lon, lat]`. **Data rules.** Companies under SIRENE partial diffusion are returned without the person's name, street address, position or building. Officers come from public registers only (name, first names, month and year of birth, mandates), without contact details.
