FCA Financial Services Register API is one of 2 APIs that [Financial Conduct Authority](https://apis.io/providers/fca-uk/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Public Register, Regulator, Authorisation, Firm Data, and United Kingdom. The published artifact set on APIs.io includes API documentation, an API reference, authentication docs, and rate-limit docs.

Read-only REST API over the Financial Services Register, the FCA's public record of authorised firms, individuals, funds and appointed representatives. Resources are addressed by Firm Reference Number, Individual Reference Number or Product Reference Number and expose sub-resources for names, individuals, permissions, requirements, passports, regulators, appointed representatives, addresses, waivers, exclusions and disciplinary history — the permissions data being where insurance authorisations (insurance distribution, insurance mediation, Lloyd's market activity) surface. Registration is free and self-serve, but the developer portal and its reference documentation are behind a Salesforce login; authentication is by X-Auth-Email and X-Auth-Key request headers. No OpenAPI or Swagger definition is published by the FCA.
