Build with Sprello
Sprello is built to be programmable — by your product, your internal tools, and AI agents. The public API base URL is https://sprello.ai/api/v1; public endpoints are JSON-only and need no authentication, while Workflow API endpoints require a per-workspace API key. All API errors are structured JSON with a code, message, and resolution hint.
Product documentation
Full documentation for the Sprello canvas, nodes, models, asset library, and account management. Agent-friendly: it serves llms.txt, and every page is available as markdown by appending .md to its URL.
docs.sprello.ai →Workflow API
Every workflow you build in Sprello becomes a callable API endpoint: send inputs, trigger a run, and receive outputs, status, and asset URLs in the response. Access is granted per workspace.
Request API access →OpenAPI 3.1 spec
A machine-readable spec covering the public agent endpoints (status, product, pricing) and the Workflow API surface, with operation IDs, typed schemas, and a structured JSON error format.
sprello.ai/openapi.json →MCP server
A Model Context Protocol server over Streamable HTTP with read-only tools: product overview, pricing, API reference, and markdown versions of key pages. Point Claude, ChatGPT, or any MCP client at it.
sprello.ai/mcp →llms.txt
A concise agent guide to this site: what Sprello is, when to use it, and where every developer resource lives.
sprello.ai/llms.txt →Markdown content negotiation
Key pages on sprello.ai support content negotiation: request any of them with an "Accept: text/markdown" header and the server returns markdown instead of HTML.
