Dune-backed charts run against the project's configured Dune API key. ## OpenAPI ````yaml GET /v0/boards/{boardId}/charts/{chartId}/query openapi: 3.1.0 info: title: Formo Public API description: >- REST API for managing Formo projects, analytics, alerts, boards, charts, contracts, segments, and AI chat. **Auth.** All endpoints require a workspace API key with the appropriate scopes (see `x-api-scopes`). **Response shape.** Successful responses return the resource directly (or `{ data: [...], total, page, size, has_more }` for paginated lists). HTTP status carries success/failure; there is no envelope wrapping success bodies. **Errors.** Every non-2xx response uses the `Error` envelope: `{ error: { code, message, doc_url, param?, details? } }`. Branch on the machine-readable `code` (see `ErrorCode` enum) and follow `doc_url` to the matching section of the [errors reference](https://docs.formo.so/api/errors). **Idempotency.** Pass an `Idempotency-Key` header on POST/PUT/PATCH/DELETE to make retries safe; the response is cached for 24 h and replayed on duplicate keys. version: 0.1.0 contact: name: Formo url: https://formo.so servers: - url: https://api.formo.so description: API Server (boards, alerts, contracts, segments, profiles, query, import) - url: https://events.formo.so description: Events Server (event ingestion) security: - WorkspaceApiKey: [] tags: - name: Alerts description: Manage project alerts and notifications - name: Boards description: Manage dashboard boards - name: Charts description: Manage charts within boards - name: Contracts description: Manage blockchain contract monitoring - name: Segments description: Manage user segments - name: Profiles description: Wallet profiles and import - name: Query description: >- Execute SQL queries and call pre-built analytics endpoints (KPIs, top pages, lifecycle, retention, revenue).
