No uploads, no sign-up, no limits.\n\nThis API runs the same tool functions the website runs. Each tool is a pure function of its inputs: no network access, no file system, no stored state — so a call has no side effects and is safe to retry.\n\n### What is not here\n\nTools that need a browser (canvas, media devices, WebAssembly), that take file uploads, or that produce binary files are excluded rather than exposed and left to fail. Their web pages still work.\n\n### Reading a tool schema at runtime\n\n`GET /api/v1/tools` returns the whole callable catalogue with an `inputSchema` for each entry. `GET /api/v1/tools/{slug}` returns one tool, its input schema and its output schema. This document describes the same thing statically, one operation per tool.\n\n### MCP\n\nThe same catalogue is callable over the Model Context Protocol at `https://convertto.tech/api/mcp` (Streamable HTTP, stateless). The `inputSchema` an MCP client receives is generated by the same code as the request bodies below.\n\n### Limits\n\nRequest body 256 KB; one run 5000 ms; response 1024 KB; 60 requests per minute per client (best effort).","contact":{"name":"Convertto","email":"hello@convertto.tech","url":"https://convertto.tech"},"license":{"name":"Free to use","url":"https://convertto.tech/terms"}},"servers":[{"url":"https://convertto.tech","description":"Production"}],"tags":[{"name":"catalogue","description":"Discovery."},{"name":"mcp","description":"Model Context Protocol."},{"name":"a11y","description":"7 tools."},{"name":"ai","description":"5 tools."},{"name":"calculators","description":"46 tools."},{"name":"color","description":"9 tools."},{"name":"crypto","description":"12 tools."},{"name":"css","description":"31 tools."},{"name":"data","description":"31 tools."},{"name":"datetime","description":"17 tools."},{"name":"developer","description":"29 tools."},{"name":"encoding","description":"16 tools."},{"name":"health","description":"8 tools."},{"name":"image","description":"1 tools."},{"name":"media","description":"5 tools."},{"name":"network","description":"1 tools."},{"name":"number","description":"11 tools."},{"name":"random","description":"9 tools."},{"name":"samples","description":"12 tools."},{"name":"seo","description":"10 tools."},{"name":"social","description":"4 tools."},{"name":"text","description":"44 tools."},{"name":"unit","description":"22 tools."}],"externalDocs":{"description":"Tool index for language models","url":"https://convertto.tech/llms.txt"},"paths":{"/api/v1/tools":{"get":{"operationId":"listTools","summary":"List every callable tool","description":"The catalogue, with the JSON Schema for each tool's input.
