x402 Pay-Per-Call Service Directory Search (x402 List)
x402list/services-list
Search the x402 List directory of services that accept per-request payments over the x402 protocol (1009 at the time of writing). Filter by free-text need q, category (AI, Blockchain, Compute, Content, Data, Finance, Other or Verification), status (online, degraded, offline, unknown) and payment_ready, sort by newest, uptime, cheapest or endpoint count, and page through with page and per_page (1 to 50, required). Each service comes back as a summary: slug, name, base and website URLs, category, status, verified, payment_ready, endpoint count, lowest per-request amount in US dollars, networks, 24-hour uptime, average response time, last check time and a description cut to 300 characters; use the lookup tool for the full record. The response carries the licence and the credit line to show. Data from x402 List (CC BY 4.0), trimmed as described and served by Eden Engine; not an official x402-list.com product.
