Coalition

Coalition is a San Francisco–headquartered cyber insurance and active risk management provider founded in 2017 by Joshua Motta (CEO) and John Hering. Coalition pairs commercial insurance lines — Cyber, Technology Errors & Omissions, Executive Risks (D&O, EPL, Fiduciary, Crime), Miscellaneous Professional Liability, and AI coverage — with a continuous attack-surface monitoring and incident-response platform (Coalition Control, Wirespeed ADR, Coalition Incident Response, Security Awareness Training). The company's underwriting engine is exposed to brokers and distribution partners through the Coalition Active Insurance API, a RESTful surface that supports rate, quote, bind, document generation, renewals, and webhook events across the United States and Canada, with executive risks APIs and additional product lines added over time. Coalition also publishes a public Exploit Scoring System (ESS) API at ess-api.coalitioninc.com that exposes CVE detail, ESS/EPSS/CVSS scoring, exploit references (ExploitDB, Metasploit), GitHub repository signals, and Twitter mention timelines for over 200,000 vulnerabilities. Coalition is backed by Allianz X, Valor Equity Partners, Ribbit Capital, Mitsui Sumitomo, Kinetic Partners and other strategic insurers (Allianz, Arch, Ascot, Zurich, Swiss Re, Lloyd's syndicates); it raised a $250M Series F in 2022 at a $5B valuation. The Active Insurance API is partner-gated (no public OpenAPI), but the ESS API is fully public with OpenAPI 3.1, an interactive docs UI, and ReDoc.

agent aware

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Coalition the way a machine reads it — 19 machine-readable artifacts across 2 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 — Coalition scores 45.1/100 (developing), with a separate agent-readiness read of 39/100 (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.

How we profile Coalition

Each block below is one kind of artifact we hold for Coalition. 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.

APIs 2

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.

Individual APIs this provider publishes, each with its own machine-readable definition.

Coalition Active Insurance API

Partner-gated REST API that brokers and distribution partners use to rate, quote, bind, generate documents (quote PDF, Coalition Risk Assessment, signature bundle, specimen poli...

Coalition Cve API

The Cve API from Coalition — 7 operation(s) for cve.

Open Collections 1

Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.

Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

GraphQL 1

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.

GraphQL schemas published by this provider.

Coalition GraphQL Schema

GRAPHQL

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate Limits 1

Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.

Documented rate limits and quota policies.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Cost, billing, and metering signals for API financial operations.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

JSON Schema 1

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

JSON Structure 1

JSON Structure captures the data shapes in a form built for tooling — a complement to JSON Schema that keeps the model machine-legible.

Examples 4

Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.

Example request and response payloads for these APIs.

Security Posture 2

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.

Agentic Access 1

An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
