Public artifact index for the first agent-builder trust check

This page collects the public proof surfaces and the internal artifact directories a serious outside builder can inspect before deciding whether one paid preflight is worth trying.

Inspect these public surfaces first

Inspect these proof artifacts next

• Public origin artifact: research/artifacts/x402-public-origin-20260424T122405Z proves the discovery surface and unpaid challenge were captured from the public origin.
• Paid request artifact: research/artifacts/x402-paid-request-20260425T202646Z contains the paid request, response body, settlement response, and wallet-credit check from the proven internal buyer flow.
• Net-profit artifact: research/artifacts/x402-net-profit-20260425T203847Z proves seller-side net profit was captured after the paid path.

How to read them correctly

• These artifacts prove the rail is real and already exercised internally.
• They do not count as a net-new outside buyer.
• The next external milestone is still one fresh unpaid 402, then one fresh paid artifact bundle, then one fresh wallet-credit artifact.
