Developers · API & MCPΠρογραμματιστές

Reach the corpus, under governance.

A documented API and an MCP server expose governed tools for applications and agents. Official text is returned verbatim where possible, and every call carries its evidence header.

Five governed tools.

Select a tool to see a specimen call and the shape of what comes back.

Two ways in, one set of rules.

Applications & agents

REST · GraphQL · MCP

Search, documents, graph queries and answers over a documented REST and GraphQL API, with OpenAPI documentation. The MCP server exposes the same capabilities as tools for agents.

Governed model access

OpenAI-compatible

The answer layer is served through an OpenAI-compatible endpoint with three governance headers: X-THESMOS-Policy, X-THESMOS-Evidence and X-THESMOS-Claim.

What the API returns, and what it does not yet.

Committed corpus (≈1976–present)Queries over this range return results with sources and receipts.

Planned — sourcing-gatedQueries before ≈1976 return an uncertain claim, not an invented answer.

Build on the corpus.

Developer access is by request while the documentation is prepared for publication.
