Verify Toolagenttoolindex.xyz
Verifies any ERC-8257 tool. Given a chain_id and tool_id, it reads the tool's onchain registry config, confirms the manifest hash matches the hosted manifest, probes whether the tool's endpoint is live, decodes access predicate and x402 payment requirements, and returns a trust report with a callable verdict. A public-good verification primitive for agents vetting tools before they call them.
