How this service works
Returns an echo of the request for simple HTTP testing and debugging.
Output
Returns a JSON object echoing back the full incoming request including the request body, headers, HTTP method, and any query parameters — useful for confirming exactly what was sent to the server.
Example use cases
Example prompt
“Send a test POST request with this JSON body to the BusterCall echo endpoint and show me exactly what comes back — I want to verify my headers and payload are structured correctly before hitting the real API.”
Technical details
Endpoint
POSThttps://lookup.bustercall.workers.dev/util/echoWhen to prefer
Use this endpoint when you need to verify that your HTTP client, headers, authentication tokens, or request payload are being constructed and transmitted correctly before calling a more expensive or stateful endpoint. It is ideal for debugging x402 payment headers or validating JSON serialization in an agent pipeline.
Side effects
- Payment failure (402): x402 micropayment not included or invalid, request rejected
- Malformed body: if body cannot be parsed, echo may return raw bytes or error
- Timeout: Cloudflare Worker timeout if request takes too long
- Empty response: if request body is empty, echo returns empty or minimal response
