aid: lloyds-of-london url: https://raw.githubusercontent.com/api-evangelist/lloyds-of-london/refs/heads/main/apis.yml name: Lloyd's of London kind: company description: >- Lloyd's of London is the world's specialist insurance and reinsurance market, operating as a regulated marketplace rather than as a carrier: the Corporation of Lloyd's oversees syndicates, managing agents, brokers and coverholders who underwrite property, casualty, marine, aviation, energy, cyber, political risk and reinsurance business on a subscription basis from its home market in the United Kingdom. Its API posture reflects that role. Lloyd's is a standards and market-infrastructure publisher first — the Core Data Record (CDR), the Market Reform Contract (MRC), coverholder and delegated claims reporting standards, and Blueprint Two digital processing requirements — and its technical surface is aimed at brokers, syndicates and market vendors, not at outside developers. Lloyd's ran a public API Development Portal at developer.lloyds.com (the "API Factory", BETA from June 2020) that published a Base API Standard and a catalogue of three market APIs: Placing — Submission and Quote, Placing — Firm Order, and RPAC for delegated authority risk, premium and claims. That portal now redirects to www.lloyds.com and no replacement self-serve developer portal is published. Production access to the underlying London Market API gateway (https://api.londonmarketgroup.co.uk) has always been partner-gated: an organisation must be onboarded to LIMOSS Common Services, registered in the Common Services Azure Active Directory tenant, and register an X.509 certificate before it can call anything. There is no public, self-serve Lloyd's API, no public sandbox and no public downloadable specification reachable today — the honest record for this market body is documentation-and-standards-first. What Lloyd's does still operate, verified by live probe, is a genuine gated API estate: three isolated gateway environments (Sandbox, PreProd, Production), an OpenID Connect discovery document and JWKS published on each, and a routed Catastrophe Codes v1 endpoint whose unauthenticated /health meta resource answers 200 while its data resources return 401 "Client certificate is missing". Its most reusable public artifact is the Lloyd's Base API Standard — a normative RFC 2119 document fixing the resource model, query grammar, collection and error envelopes, versioning compatibility rules and the dual mutual-TLS + JWT security model for every API published to the market. image: https://kinlane-images.s3.amazonaws.com/shared/apis-json/apis-json-logo.jpg tags: - Insurance - United Kingdom - Reinsurance - Specialty Insurance - London Market - Underwriting - Claims - Delegated Authority - Broker - Market Infrastructure - Standards - ACORD created: '2026-07-25' modified: '2026-07-25' specificationVersion: '0.19' apis: - aid: lloyds-of-london:lloyds-placing-api-submission-and-quote name: Lloyd's Placing API - Submission and Quote v1 description: >- Market API for electronic placement in the London subscription market — create submissions and submission versions, upload Market Reform Contract and quote documents, add carriers and underwriters to a submission, send requests for quote, and receive underwriter responses (reject, express interest, request for information, or quote). Published by Lloyd's under the API Factory programme with a Swagger/OpenAPI 3.0 document (Swagger_PlacingSubmissionAndQuote_v1.10.202004160916.json) offered for download from the developer portal. Access is partner-gated to onboarded London Market organisations via LIMOSS Common Services, Azure AD tokens and a registered X.509 certificate; the developer portal that hosted the reference and the specification now redirects to www.lloyds.com, so the spec could not be harvested.

This API was never listed in the Lloyd's API catalogue; it surfaced because the Lloyd's Base API Standard uses it for every worked example of the identity pseudo-field and the collection wrapper document. It is the only Lloyd's API surface still routed on the gateway: probed on 2026-07-25 the unauthenticated /health meta resource mandated by section 5.11 of the Base API Standard returns 200 on both Production and Sandbox, while /CatastropheCodes and /version return 401 {"Code":401,"Message":"Client certificate is missing."} — the mutual-TLS gate is live and enforcing. Access requires LIMOSS Common Services onboarding, an Azure AD on-behalf-of token with scp=user_impersonation, and a registered X.509 certificate per environment.
