API reference

Every tool is available two ways: as an MCP tool, and as POST https://supapublish.com/api/v1/<tool> with a JSON body of arguments. Read-only tools also accept GET with query parameters. Responses are { "data": … }, or { "error": "…" } with an HTTP status (see Errors). A machine-readable version is at /openapi.json.
