Independent health monitoring for x402 endpoints.

x402market tracks x402 endpoints across categories (AI, security, finance, DeFi, analytics), checks liveness and latency, and keeps historical operational signals.

Built for developers who want operational signal before integrating or paying.

Method

Scores are derived from repeated checks, response latency, metadata quality and stability signals. The goal is straightforward: highlight which endpoints look operationally reliable.

Recent events

    Why this exists

    • Discovery catalogues list endpoints, not operational quality.
    • x402market tracks liveness, latency and confidence over time.
    • No paid ranking, no sponsored boost, no hidden provider weighting.
    • Quality scoring stays separate until there is real demand.

    Coverage

    Monitoring expands over time as the crawler observes more of the ecosystem and builds a stronger operational picture across endpoint categories.
