How this service works
x402 merchants ranked by measured settlement rate over the last 30 days: how often a paid request actually produced an on-chain settlement, not how often the endpoint was up
Output
An ordered list of x402 merchants ranked by their measured on-chain settlement rate over the trailing 30-day period, showing how reliably each merchant's paid endpoints actually result in confirmed blockchain settlements rather than just uptime metrics.
Example use cases
Vetting reliable x402 API vendors
“Before I build my agent on top of x402 APIs, show me which merchants have the highest settlement rates over the last 30 days so I can pick trustworthy ones.”
Auditing x402 ecosystem quality
“Pull the current x402 merchant settlement rankings — I want to see which endpoints are actually settling payments on-chain versus just accepting requests without following through.”
Monitoring x402 payment reliability trends
“Give me the ranked list of x402 merchants by settlement rate so I can flag any well-known providers that have dropped in reliability this month.”
Technical details
Endpoint
GEThttps://whaletape.xyz/index/rankingWhen to prefer
Use this endpoint when you need to evaluate x402 merchant trustworthiness based on actual on-chain settlement behavior rather than self-reported uptime. Prefer this over general API health checks when your agent needs to select or audit x402 payment endpoints based on settlement reliability.
Side effects
- No data if measurement cycle hasn't completed
- Stale rankings if on-chain data indexing is delayed
- Empty list if no x402 merchants have been measured yet
- HTTP 402 if payment of $0.03 USDC is not included in request
- Ranking may not reflect real-time settlement status
