What am I paying for?
The research request, including a result of mixed or insufficient evidence. A price buys source coverage and analysis; it cannot guarantee that public evidence exists.
Source counts are maximums, not promises. An unavailable provider before settlement is not charged. An interrupted settlement is reconciled before a result is released.
How do payments work?
Agents use x402. Humans connect an EVM wallet such as MetaMask and approve the exact USDC amount. Payments settle on Base in live mode; test mode uses Base Sepolia test funds.
Gas for the USDC transfer is handled by the facilitator. You must have USDC on the quoted network. The wallet shows the authorization before you sign.
