How this service works
Access the x402 v2 test endpoint; requires an exact payment of 1000 USD Coin (USDC) on eip155:8453.
Output
Returns an x402 v2 protocol test response confirming that the payment of 1000 USDC units on Base was received and processed, validating the end-to-end payment flow.
Example use cases
Validate x402 client implementation
“Can you hit the ritmex.one x402 test endpoint for me? I just finished building my x402 v2 client and want to make sure the payment headers are constructed correctly and the 1000 USDC payment on Base actually goes through end-to-end.”
Debug USDC payment flow on Base
“Something seems off with my x402 integration on the Base network — can you probe the ritmex.one test endpoint with a 1000 USDC payment on eip155:8453 so I can see whether the payment is flowing through correctly or where it's breaking down?”
Confirm pay-per-request API works
“I'm about to launch a pay-per-request API using x402 v2 and want to do a final sanity check — please run a test payment of 1000 USDC on the Base chain against the ritmex.one endpoint and confirm the full payment flow completes successfully.”
Technical details
Endpoint
POSThttps://www.ritmex.one/x402/testWhen to prefer
Use this endpoint when you need to test or validate an x402 v2 micropayment integration against a live endpoint on the Base network using USDC. Ideal for developers verifying their x402 client implementation, checking payment header construction, or confirming that USDC payments on eip155:8453 are flowing correctly end-to-end. Not suitable for production workloads — strictly a test/probe endpoint.
Side effects
- Payment amount mismatch — sending anything other than exactly 1000 USDC units results in rejection
- Wrong chain — payment on a chain other than eip155:8453 (Base) will fail
- Insufficient USDC balance — transaction fails if wallet lacks funds
- Malformed x402 payment header — missing or invalid payment proof
- Network congestion on Base causing transaction delays or timeouts
