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 APIs on the APIs.io network: Entity API API, Query API API, and Schema API API. Tagged areas include Company, Knowledge Graph, Data Enrichment, Entity Data, and Company Data.

Golden Recursion’s developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, authentication, and 24 more developer resources.

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.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/golden-recursion: open an issue to ask a question, or submit a pull request to add artifacts.

  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.
