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.
