## OpenAPI

openapi: 3.1.0
info:
  title: route
  version: 2.15.0
  description: >-
    Route compares swap paths offchain and executes swaps on Robinhood Chain.
    The API returns quotes and unsigned transactions. It does not sign or submit
    for you. V2 deducts a disclosed pair-dependent output fee up to 0.50%; pool
    fees, provider charges and gas may still apply. Contracts are experimental
    and unaudited. Public routing and data endpoints require no API key. Use the
    documented /api/v2 endpoints for integrations. Builder endpoints require a
    scoped x-api-key from build.route.fun. Public quote, swap and data endpoints
    remain keyless.
