Paid responses are produced by the live IncorpSignal API from Companies House-backed records. They include source and provenance fields, explicit schema versions, bounded arrays, and compact projections. Bazaar discovery examples are non-empty checked snapshots rather than placeholder data.
Scout Plus includes rate-limited /v1/* API keys. Read the Swagger UI or OpenAPI schema.
