Sourcing tools for autonomous agents.
Give agents structured product discovery with transparent, per-request payment. PartHound exposes Bazaar metadata in its x402 payment offer so compatible clients can inspect its input and output contracts.
Machine-readable
Input/output schemas accompany the payment offer.
Evidence-aware
Ranked sources include warnings and verification fields.
Wallet-controlled
Agents must use compatible EOA wallets with explicit spending limits.
Safe retries
Operation IDs protect paid workflows from duplicate settlement.
Recommended agent workflow
Construct a valid sourcing request, inspect the 402 offer, verify the Base mainnet network and USDC amount, obtain wallet authorization under a strict spend policy, and resubmit the same request with the same operation ID. Read the returned evidence and treat source availability as unconfirmed until independently verified.

Discovery is not universal indexing
Publishing Bazaar metadata helps compatible tools understand PartHound, but it does not guarantee listing in any particular discovery index. Confirm indexing independently before relying on it.
