TrustBench

If you're building agents that make paid x402 calls, this gives you three verification primitives: query TrustBench's provider rankings across Base and Solana networks, fetch cryptographically signed payment receipts by ID, and verify Ed25519 signatures plus on-chain settlement status without trusting a third party. The registry covers roughly 650 services on Coinbase Agentic Market and 150 Solana endpoints from Heurist Mesh, with nightly liveness probes and a public scoring methodology. Every receipt links to an immutable audit trail at trustbench.io/receipts, and the verification tool checks both signature validity and Base settlement in one call. Reach for this when you need proof that an x402 payment actually settled, or when you want ranked provider discovery before routing a paid request.
