How we checked: Once a day we call each listing’s example search endpoint without paying and read the HTTP 402 reply: whether it answered, whether the reply is a valid x402 payment request, the price and network it asks for, and how long it took. One call each per day, so latency is a rough median, not a benchmark. Raw data: api.youraitools.co/stats/v1/listings/exa and /you-com. Results quality is not measured here, and prices vary by route, so confirm with each provider before paying.
Measured by us: the x402 endpoints
We call these x402 endpoints daily without paying and read the HTTP 402 reply. Not a ranking.
What the numbers show
- Both answered every check. Each search endpoint was up and returned a valid x402 v2 payment request on all 8 daily checks since Oct 27, 2026.
- Price per search in the 402. Exa’s /search asked for $0.007 and You.com’s /v1/search asked for $0.005, both in USDC on Base. Each lists a wider range for other routes ($0.001–$0.007 for Exa, $0.005–$0.11 for You.com).
- Trust score. You.com scores 97 of 100 on our trust formula (uptime, valid 402, price match, latency). Exa isn’t scored yet because our check’s target changed on Oct 30 and needs 7 days of new data.
