Preflight a tool before another agent trusts or pays it. Fetches a live ERC-8257 ai-tool manifest, validates it with @opensea/tool-sdk, computes the manifest hash, compares it to Base ToolRegistry state, checks the Tool Pass predicate collection when present, and probes the endpoint for live/payment status. Built for provenance, cadence, and failure-semantics checks before agent-to-tool spend.

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.
