OpenAPI Specification

clean-tools-finance-api-openapi.yml Raw ↑ 
openapi: 3.2.0
info:
  title: Clean.tools Finance API
  version: 0.1.0
  summary: Read-only developer, finance, date, and text utilities. No key, no signup.
  description: 'Every endpoint is read-only and side-effect-free. Most tools are deterministic: same input, same output. The generator tools (uuid_v4, generate_id, random_number, generate_password) use cryptographic randomness instead. Requests are processed in memory and never written to storage or logs; only anonymous per-tool call counters are kept. The same tools are available over the Model Context Protocol at POST /mcp (mount a subset with ?tools=). Rate limit: about 60 requests/minute per caller — honor Retry-After on 429 and add jitter.'
