  description: 'Public JSON API for Spanish company information derived from BORME and other public sources. OpenMercantil is an independent informational service; it is NOT the BOE, BORME or Registro Mercantil and does NOT replace official certificates or registry extracts.


    **Rate limits.** Free: 60 req/min y 200 req/día por IP. Planes superiores (Profesional 5.000 req/día, MAX 50.000 req/día, Enterprise 500.000+ req/día) según cuenta y API key. Cabeceras `X-RateLimit-Limit`, `X-RateLimit-Remaining`, `X-RateLimit-Reset`, `X-OpenMercantil-Plan`, `Retry-After`.


    **License and attribution.** Source-specific metadata in each response and the active versioned source catalog prevails. OpenMercantil does not relicense upstream content under a blanket license. Unknown, review and restricted datasets are omitted or return `503 legal_layer_unavailable`. BOE/BORME material is re-used under Ley 37/2007 and its official version remains boe.es. Court judgments are not exposed; CENDOJ remains citation-index only under CGPJ Reglamento 3/2010.

  x-contract-status: Public read, browser-account and provider-callback surfaces are explicitly separated in this contract. Operator/admin routes are excluded. The public MCP consumes only the allowlisted GET read plane.
  x-account-segment-contract:
    projection: company_public_v2 immutable corporate sidecar
    synchronous_row_cap: 500
    bounded_count_cap: 50001
    count_semantics: The segment run response count is the number of rows returned, never a global total. Dataset preview uses total_is_lower_bound=true and total_lower_bound when the bounded count reaches 50001.
    related_web_dataset_surface:
      preview_path: /mi-cuenta/datasets/preview
      export_path: /mi-cuenta/datasets/export.csv
      synchronous_export_max_rows: 500
      overflow_status: 503
      overflow_error: async_export_required
  x-company-identity-contract:
    version: '1.0'
    projection: company_public_v2 immutable generation-bound corporate sidecar
    applies_to: Every /api/v1/company/{slug}*, /api/v1/empresa/{slug}* and /api/v1/grafo/{slug} read before any report, cache, graph or dataset lookup. /api/v1/companies/compare resolves both requested subjects in one bounded company_public_v2 batch before either row is exposed; MCP company tools inherit these preflights through REST.
    resolution:
      published: canonical corporate slug admitted
      safe_alias: internally canonicalized and Content-Location emitted
      withheld: neutral 404; includes absent, personal and ambiguous/quarantined identities
      unavailable: 503 with no-store; clients must not infer absence
    search: Exact corporate CIF, exact canonical/safe-alias slug, or bounded name_prefix2 pool scored in application code. DNI/NIE and ambiguous CIFs return zero items.
