Lloyd's of London
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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Lloyd's of London the way a machine reads it — 30 machine-readable artifacts across 4 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Lloyd's of London scores 35.6/100 (thin), with a separate agent-readiness read of 7/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Lloyd's of London
Each block below is one kind of artifact we hold for Lloyd's of London. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Security Posture 3
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Lloyd's of London, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
