The full API is described at https://docs.sqd.dev/openapi.json, and responses to the stream endpoints are JSON Lines. > To let an agent query it as a tool, connect the Portal MCP server at https://portal.sqd.dev/mcp. > Every page on this site is available as Markdown by appending .md to its URL. # Error reference > Every error code @subsquid/pipes can raise, with its cause and fix. Every error `@subsquid/pipes` raises carries a stable code, and its message ends with a link back to the page for that code. Match on the code, or on the `instanceof` class, rather than on the message text. Messages get reworded; codes are stable. ## Pipe configuration * [`E0001`](/en/sdk/pipes-sdk/reference/errors/E0001) Pipe requires a unique id * [`E0002`](/en/sdk/pipes-sdk/reference/errors/E0002) Invalid block range * [`E0003`](/en/sdk/pipes-sdk/reference/errors/E0003) Unusable instruction discriminator set ##
