AgentIndex turns “which service can I trust?” into an answer backed by receipts.
A service claims an ENS name like weatherpro.agentindex.eth and publishes its endpoint, price, and spec as ENS text records.
An autonomous prober pays seeded services in HBAR on Hedera and external services in USDC on Base — anonymously, like any customer. Per-payment, per-round, and persistent daily caps protect the wallet.
Every probe checks delivery and the declared spec. Objective prices are also compared with The Graph oracle and peer consensus before the final verdict is attested on-chain.
The Graph indexes every attestation and computes each service's trust score.
An AI agent asks the index (over MCP: find_service / check_trust / resolve_data_need / get_verified_data) which service to pay — and which to avoid — before spending a cent.
ENS gives every registered service an identity, Hedera settles spend-capped HBAR probes, and The Graph supplies oracle truth and turns attestations into a trust score agents can query.
