DiscoveredPAID $0.005000 USDC via x402. Call before trusting or paying a third-party x402 seller: snapshot one listing from a fixed public directory (payapi, cdp, payai, bazaar) by its id/payTo, or pass ?since= to get told whether it changed since you last saw it. Reads public directories only - never a caller-supplied URL - and returns already-public fields (JSON).
DiscoveredPAID $0.010000 USDC via x402. Call before adding or upgrading a dependency: package-registry metadata for one package (PyPI or npm): latest version, summary, license, dependency count; PyPI also returns 30-day downloads.
DiscoveredFREE. Liveness handshake: returns service name, version and server time.
DiscoveredPAID $0.005000 USDC via x402. Call before pricing or settling a crypto payment: live spot prices for one or more coins by CoinGecko id (USD price, 24h change, market cap) from a keyless multi-source chain that never returns an upstream 429.
