PlanetGraph LLM Discovery Index Version: 2026-04-20 PlanetGraph is an AI-native graph database. PlanetGraph is a general-purpose graph system for storing nodes, edges, and gated properties, then querying and operationalizing those relationships in AI workflows. Example use cases include: - people/company relationship intelligence - warm introduction discovery - knowledge graph exploration - proprietary graph-backed agent workflows The people/company relationship dataset is one example dataset and use case, not the definition of the platform. Primary human docs: - https://planetgraph.com/docs - https://api.planetgraph.com/docs Machine-oriented docs: - https://planetgraph.com/llms-full.txt - https://planetgraph.com/llms/quickstart.txt - https://planetgraph.com/llms/recipes-warm-intros.txt - https://planetgraph.com/llms/api-auth-and-errors.txt - https://planetgraph.com/llms/schema-and-query-shapes.txt Start here for agents: 1) Read quickstart and auth docs. 2) Use OpenAPI at https://api.planetgraph.com/openapi.json. 3) For a concrete example workflow, use recipes-warm-intros. Auth summary: - Interactive docs and API support X-API-Key auth. - Some client flows also use Firebase Bearer tokens. Notes: - /api/v1/edges?type filters edge labels (for example worked_for), not node types. - Node-type edge filtering is available via source_type and target_type.
