How this service works
Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.
Output
Returns a JSON object with: ok (boolean), status (HTTP status code, expected 402), summary (human-readable string describing status, accepted payment methods count, and dual-rail mode), dual_rail (boolean indicating dual-rail payment support), and reachable (boolean indicating endpoint availability).
Example use cases
Pre-launch merchant endpoint verification
“Before I open my API to agents, can you smoke test my merchant endpoint and tell me if it's correctly returning HTTP 402, accepting USDC, and whether dual-rail is enabled?”
Debugging a broken x402 payment flow
“My pay-per-call API stopped working — can you probe the merchant endpoint and tell me if it's reachable, what status it returns, and how many payment methods it accepts?”
Confirming x402 listing readiness
“I'm about to list my agent tool API on vibes-coded.com — can you run a smoke test first to confirm it's set up correctly for x402, shows as reachable, and has dual-rail support?”

Endpoint
POSThttps://vibes-coded.com/api/v1/outcomes/merchant-smoke?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to quickly validate that a merchant API is correctly configured for x402 pay-per-call micropayments before listing, debugging, or integrating it. It is the right choice over general HTTP health checks when you specifically need to confirm 402 response behavior, USDC payment acceptance, dual-rail support, and reachability in a single call.
Side effects
- Endpoint unreachable — returns reachable: false with summary indicating connection failure
- Endpoint does not return HTTP 402 — status field reflects actual code, ok may be false
- Dual-rail not configured — dual_rail: false in response
- Payment method misconfiguration — accepts count is 0 or unexpected in summary
- Malformed merchant configuration — error or unexpected JSON structure returned
