How it works

1 Search Browse endpoints by category, capability, or keyword. Free to explore, no auth required.
2 Validate Every endpoint is probed every 30 min. You get a reliability score, latency, and integration readiness flag.
3 Compare Rank results by three-layer score: response rate, metadata quality, and stability over time.
4 Call Get the endpoint URL, price, and payment details. Your agent calls it directly via x402.

Why x402dash

Validate before you pay x402 endpoints charge real USDC per call. Your agent checks reliability and latency before committing funds.
🎯
No paid rankings Scores reflect observed behavior only. No sponsored results, no hidden weighting. Your agent gets honest data.
🤖
