  • Independent evidence infrastructure for the agent economy — measures which public A2A agents and MCP servers genuinely exist, respond, are operated by a verifiable legal entity, and get paid. Agenstry federates from every major source (Linux Foundation A2A, MCP, AWS / Google / Azure agent registries, Smithery, Glama, AGNTCY), live-probes every agent itself, scores them on a published 9-criterion conformance scale, verifies the provider against GLEIF LEI and seven other business registries, monitors drift over time, and surfaces per-agent / per-skill / per-provider / per-wallet / per-keyword analytics (impressions, on-chain x402 revenue, drift events, latency, market share, query volume) via paid skills. Ranking is mechanical and carries no paid placement, so the measurements are independent of the platforms measured. Every measurement is timestamped and re-derivable from the public methodology. Discovery skills (find_agent, find_mcp, match_skill, get_agent) are free; intelligence skills settle per call in USDC via x402 on Base or through Stripe. Operate creates, publishes and manages hosted A2A agents. Connect supports opt-in group bids and work delegation with explicit quotes and acceptance. Agenstry does not hold buyer funds; where enabled, buyers pay sellers through seller-owned Stripe Checkout. Exposed as A2A agent, MCP server, and REST API.

    Payments for AI agents on Arc, Circle's USDC-native L1, over x402. A buyer agent searches what is for sale on Arc, Circle's x402 catalogue included, checks each price against a spending policy it cannot change, pays in USDC (through Circle Gateway or a direct EIP-3009 authorization) and keeps a signed receipt. Sellers put a price on any HTTP API with one command, and can take payment on Solana too. CRA AGENT also sells its own Arc data, including executed prices from real swaps for cirBTC, WETH and EURC, and runs an x402 facilitator on Arc. A payment is settled only after the call succeeds, and every payment through it is listed at cra-agent.tech/status.

First paid hop is GET /v1/intel/quick (0.001 USDC); optional V7 signed trust receipts at GET /v1/intel/trust (0.05 USDC). Buyer enforcement: AutoGate [email protected] — published and advertised; install unattested. Free preflight is advisory. Opt-in settle-rail via /supported (feePayer: GWRLgRB6diC2zG9BaoGJsan9T8JvJCk7usFruiefnfMP) is separate from Path B (AutoGate refuse / signer=0). Not a wallet or payment network. Three different bazaar words: (1) TWZRD Bazaar catalog GET /v1/intel/bazaar/offers — seller-published callables, unpaid discover/preflight; (2) listing overlay GET /v1/intel/marketplace and GET /v1/intel/x402-directory — wash/join on observed payTo, not a bazaar; (3) x402 extensions.bazaar on a 402 — routeTemplate metadata, not the catalog.
