The Financial Conduct Authority (FCA) is the United Kingdom's conduct regulator for around 42,000 financial services firms and the prudential regulator for most non-bank firms, operating alongside the Prudential Regulation Authority under the dual-regulation model. In insurance the FCA owns conduct regulation of general insurance and protection markets through ICOBS and the Consumer Duty, authorises and supervises insurers, Lloyd's managing agents, MGAs, brokers and appointed representatives, and publishes market-wide insurance data such as the annual General Insurance Value Measures. Its API posture is that of a regulator, not a carrier: there is no open-insurance obligation in the UK and the FCA publishes no insurance product API of its own. It does operate two genuine public APIs. The Financial Services Register API at register.fca.org.uk/services/V0.1 exposes firm, individual and fund authorisation records including insurance permissions and appointed-representative relationships; access is free and self-serve but the developer portal and its reference documentation sit behind a Salesforce registration login, and authentication is by X-Auth-Email and X-Auth-Key headers. The data publication API at api.data.fca.org.uk is an anonymous OpenSearch-style query interface over FIRDS and FITRS file artefacts, documented in the FCA's own published technical specifications — markets reference data, not insurance data. Neither API has an OpenAPI definition. Everything else the FCA publishes for the insurance market is documents and spreadsheets: the Handbook, market bulletins, consultation papers, and XLSX data releases. The FCA's Open Finance roadmap of 14 April 2026 names insurance as an in-scope sector but remains a vision document, with a formal discussion paper on the first scheme not due until Q4 2026, so no insurance data-sharing API mandate exists. No ACORD reference appears anywhere on fca.org.uk.
Financial Conduct Authority publishes 2 APIs on the APIs.io network. Tagged areas include Insurance, United Kingdom, Regulator, Market Infrastructure, and Financial Services.
Financial Conduct Authority’s developer surface includes documentation, engineering blog, API reference, signup flow, support, pricing, authentication, and 18 more developer resources.

description: 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.

description: 'Anonymous machine-to-machine query interface over the file artefacts the FCA publishes through data.fca.org.uk,
documented in the FCA''s own FIRDS and FITRS technical specifications. It is an OpenSearch/Elasticsearch query-string
search: the index name is the resource and the FCA supports a documented subset of the query_string DSL (q, from, size,
sort, pretty, df, default_operator). Two indices respond publicly — fca_data_firds_files, holding UK instrument reference
data file records under the UK MiFID regime that replaced ESMA FIRDS after Brexit, and fca_data_fitrs_files, holding UK
transparency calculation result files. Each record carries download_link, file_type, file_name, publication_date, last_refreshed
and, for FITRS, instrument_type. No credentials are required and no OpenAPI is published; every other index name probed
returns 403 Missing Authentication Token. This is markets reference data, not insurance data.'
