Chestnut
Chestnut is an AI-native operating system for insurance distribution, built for insurance carriers to manage the entire producer lifecycle. The Seattle-based, Andreessen Horowitz-backed company combines a purpose-built insurance data model with an API-first architecture and an agentic AI layer, providing producer onboarding automation (including NIPR integration), hierarchy configuration, incentive compensation management, debt management, performance tracking, and compensation intelligence. Chestnut positions its platform as a system of record that bridges carriers' operational needs to an agentic AI future, with an API-first, MCP-ready backend. Its public API and developer documentation are gated for carrier customers, so no public specification is available for the catalog at this time.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Chestnut the way a machine reads it — 1 machine-readable artifact, 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 — Chestnut scores 16.4/100 (emerging), with a separate agent-readiness read of 0/100 (human only). 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 Chestnut
Each block below is one kind of artifact we hold for Chestnut. 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.
Security Posture 1
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.
