  title: RoboSystems Query API
  description: 'The REST and GraphQL API for RoboSystems — an open-source, AI-native platform for accounting, financial reporting and investment management. It powers RoboLedger and RoboInvestor.


    ## Two surfaces


    **Platform** — `/v1/…` — graphs, queries, schema, documents, search, memory, connections, billing and access. Reads are REST `GET`s; every write is a named operation at `/operations/{name}` returning an `OperationEnvelope`, accepting an `Idempotency-Key`, and streaming progress at `/v1/operations/{id}/stream`.

    → API reference


    **Extensions** — `/extensions/…` — RoboLedger and RoboInvestor, scoped by `graph_id` in the URL. Reads are GraphQL at `POST /extensions/{graph_id}/graphql` and change nothing; writes are named operations at `/extensions/{domain}/{graph_id}/operations/{name}`; analytical views read the materialized graph.

    → Extensions reference · every GraphQL query


    ## Authenticating


    `X-API-Key: rfs…` on REST, GraphQL and per-graph MCP. Browser sessions use JWTs from `POST /v1/auth/login`. The graph-agnostic MCP endpoint `/v1/mcp` takes OAuth 2.1 bearer tokens only.


    ## Connecting an AI client


    Every graph is an MCP server at `POST /v1/graphs/{graph_id}/mcp`, and `POST /v1/mcp` serves OAuth clients that pick their graph at consent.
