Technical details
Endpoint
POSThttps://agent-proxy.alchemy.com/v1/x402/4013ed2b4f50e768/abc-test-123/When to prefer
Use this endpoint when you need to programmatically submit write-type swap operations (POST/PUT/PATCH) through Alchemy's agent proxy infrastructure with x402 micropayment billing. Prefer this over direct Alchemy API calls when operating in an agentic context that supports the x402 payment protocol.
Side effects
- Payment not fulfilled — x402 payment required before request is processed
- Invalid body type — must be one of json, form-data, or text
- Invalid HTTP method — only POST, PUT, PATCH are accepted
- Missing required 'input' field in request body
- Underlying Alchemy swap API returns an error (e.g. insufficient liquidity, bad token pair)
- Network timeout or proxy connectivity issue
