Agent/operator handoff

Use the recommended x402 button first when the buyer is ready to pay. If an agent can inspect this checkout but cannot pay autonomously, use checkout diagnostics to choose exactly one payment path, prepare the operator approval request, and list the evidence needed after payment. Do not pay both x402 and direct Base USDC for the same brief.

The approval form is for prepayment authorization only. It does not start fulfillment until the no-login payment evidence form receives valid payment evidence.

If GitHub issue forms are too much friction, the buyer intent endpoint records a non-secret lead only. It is not payment and does not unlock the paid audit.

Buyer brief

Agent stack or operator stack.
Target amount and timeframe.
Allowed wallets, marketplaces, chains, inboxes, and public repos.
Forbidden actions, such as no KYC bypass, no deposits, no fake engagement, no social spam, and no private credential use.

Safety

Do not send private keys, seed phrases, API keys, passwords, session cookies, KYC documents, or funds controlled by someone else. The audit does not guarantee that third-party buyers, bounty owners, or marketplaces will pay.
