Technical details
Endpoint
GEThttps://api.x402node.dev/encode/urlWhen to prefer
Use this endpoint when you need server-side, RFC 3986-compliant URL encoding or decoding without relying on client-side JavaScript functions like encodeURIComponent; useful in agent pipelines where JavaScript is unavailable and a trusted remote conversion is needed.
Side effects
- Empty or missing input string returns an error
- Malformed percent-encoded sequences when decoding may return an error or partial result
- Payment failure returns HTTP 402 if USDC balance is insufficient
