P0 x402 Market Index

Use when you need callable agent services for a capability across protocols: x402 listings ranked by relevance weighted by 30-day paying wallets, plus hosted MCP servers from the Official MCP Registry (a capped subset, count in coverage; those naming x402, L402, MPP or pay-per-call first; that registry publishes no prices).

Demand comes from P0's own on-chain count to the sellers' wallets (wallet-level, not per resource)

Use when an agent needs to know how it is seen from outside: its public IP plus the country, region, city, ASN, AS organization, Cloudflare colo and TLS/HTTP version recorded by Cloudflare's edge for this connection.
