Golden Recursion

Golden Recursion Inc. builds Golden, a San Francisco company using machine intelligence to construct a self-building knowledge graph of millions of connected entities — companies, people, venture-capital firms and products — each described by structured, cited properties. The Golden API v2 gives developers read-only, programmatic access to the same data that powers the Golden Query Tool: retrieve entities and their cited properties, pull the results of saved queries by ID or permalink, and introspect the entity-type and predicate schema. Responses are structured JSON with underlying source citations so every value can be traced. Authentication is a simple apikey header. Golden also published godel, an open-source Python SDK for its separate golden.xyz protocol GraphQL API. Backed by a16z ($59.5M raised); Golden was acquired by ComplyAdvantage on 2024-04-24 and golden.com now serves an acquisition notice, though the API v2 endpoints and the Scalar API reference at docs.golden.com remain live and were re-verified 2026-08-14.

Golden Recursion publishes 3 API contracts indexed on the APIs.io network: Entity API, Query API, and Schema API. Tagged areas include Company, Knowledge Graph, Data Enrichment, Entity Data, and Company Data.

The Golden Recursion catalog on APIs.io includes 1 Spectral governance ruleset.

Golden Recursion’s developer surface includes engineering blog, documentation, API reference, getting-started guide, support, pricing, signup flow, and 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Protected Resource Metadata +5 pts — a served /.well-known/oauth-protected-resource carrying `resource` (documented), and naming its authorization_servers (verified)

  note: Round 2. Re-verified the live contract (docs.golden.com/openapi.json is byte-identical to the captured original).
    Added plans + rate-limits from the provider's own pages and a live header probe. Corrected the packages artifact (godel/goldnlp
    are name-only on PyPI with zero published files) and the lifecycle artifact (ComplyAdvantage acquisition 2024-04-24; docs
    are a static snapshot after the "pathfinder" spec server was decommissioned 2026-07-02). Removed Blog and Roadmap pointers
    and repaired Support/TermsOfService/PrivacyPolicy, which pointed at soft-200 SPA shells.
