API Reference

The Logion v1 API: 125 operations across 27 groups, generated from the published OpenAPI contract.

This page and every page under it are generated from contracts/openapi/v1.json, which is produced by the API itself and hash-locked in the repository. Nobody can edit it by hand, so the reference cannot describe an endpoint the deployed API does not serve.

Authentication

An API key travels in a bearer header:

Authorization: Bearer lg_…

logion identity onboarding provisions a key, and the CLI sends it for you — which is the reason to prefer a command over a raw call.

One honest limit. The contract marks this header optional on every route that accepts it, because the API enforces authentication in the handler rather than in the schema. So this reference can tell you which operations take a key, and cannot tell you which ones reject an anonymous call. Assume any operation that lists the header needs one. Nothing here guesses past what the contract actually states.
