Hiscox
Hiscox Ltd is a diversified international specialist insurance and reinsurance group with roots in the Lloyd's of London market dating to 1901, domiciled in Bermuda and listed on the London Stock Exchange, operating from 31 offices across 13 countries. Its home market is the United Kingdom, where it underwrites through three segments: Hiscox Retail (small business, professional and specialty personal lines sold direct and through brokers in the UK, Europe and the USA), Hiscox London Market (larger and more complex specialty risks written out of London for a worldwide client base, including marine, energy, aviation, specialty property and casualty, and cyber), and Hiscox Re & ILS (reinsurance and insurance-linked securities). Its API posture is partner-gated rather than public. Hiscox operates a genuine first-party developer portal at developer.hiscox.com serving its US small-business arm, and that portal publicly enumerates three active APIs - Eligibility, Quote v4 and Setup Payment - but every reference document, sandbox credential and OpenAPI/Swagger file sits behind a login that is only issued after a Hiscox Partnership Manager approves a commercial partnership. There is no self-serve signup, no downloadable specification and no public claims or FNOL API. The group does ship APIs outside that portal: Hiscox London Market launched a Cargo API for small cargo and stock throughput risks in June 2025, built in-house and distributed through broker partners as coverholders, but it has no developer portal listing, no documentation and no specification - it is announced through the newsroom and reached through a broker partnership. Authentication is OAuth 2.0 plus a partner-issued API key over TLS 1.2 only, all APIs are REST, and both XML and JSON are supported. Hiscox's most concrete open-standards footprint is ACORD rather than REST: in July 2025 ACORD and Howden announced that ACORD Standards for digital accounting and invoicing went live in the UK retail insurance market with Hiscox as the receiving insurer, responding in real time to Howden's digital invoices through the ACORD Solutions Group ADEPT (ACORD Data Exchange Platform & Translator) receiver portal.
Hiscox publishes 4 APIs on the APIs.io network. Tagged areas include Insurance, United Kingdom, Property and Casualty, Specialty Insurance, and Cyber Insurance.
Hiscox’s developer surface includes documentation, API reference, FAQ, support, signup flow, getting-started guide, engineering blog, and 15 more developer resources.
