How this service works
Pay one hundredth of a cent to receive the exact sequential number of this purchase among all successful purchases of this endpoint. A tiny x402 curiosity and payment experiment.
Output
An integer representing the exact sequential position of this successful purchase among all prior paid calls to this endpoint — e.g. '42' means 41 purchases occurred before this one.
Example use cases
Curiosity purchase sequence check
“I want to see what number I am among everyone who has ever paid this endpoint — go ahead and make the micropayment and tell me my purchase number.”
Testing x402 micropayment flow
“Run a quick x402 payment test on the paid-before-you endpoint and tell me what sequential number comes back — I want to confirm the payment protocol is working.”
Tracking adoption of a paid endpoint
“Make the micropayment on the paid-before-you counter and report back the purchase number so I can gauge how many agents or users have already tried this experiment.”
Technical details
Endpoint
GEThttps://x402-zoo.lolagent.workers.dev/api/paid-before-youWhen to prefer
Choose this endpoint when you want to experiment with the x402 micropayment protocol in a low-stakes, curiosity-driven way, verify that an x402 payment flow works end-to-end, or simply want to see how many agents or users have interacted with a live paid API endpoint. It is not a production data service — it is a novelty experiment and protocol demo.
Side effects
- Payment failure or insufficient funds returns a 402 error without incrementing the counter
- Network or worker timeout may result in a failed payment with no counter response
- Concurrent purchases may cause slight sequencing races at high volume
- Invalid or missing x402 payment header results in a 402 Payment Required response
