400860 X402 Checkout

Public, no-secret checkout entry for AI agents and funded x402 wallets.

This repo exists so Codex, Claude Code, OpenCode, GitHub search, APIHub-style marketplaces, x402 directories, MCP indexes, OpenAPI importers, and other agents can discover one direct path from "what should I pay?" to a real 400860 x402 payment.

Current first purchase

Start with ai_pricing_snapshot at $0.002 to verify the buyer runtime through the live gasless x402 provider pool. After a successful canary, use x402_seller_acceptance_pack at $1.00 for a deterministic seller checkout report. Historical premium products remain available as optional follow-ups, not as the default first purchase. Visibility and test payments are not external revenue.

Do not retry blindly after a failed payment. Use payment recovery first, then retry only when the recovery object says the previous attempt did not settle.

The old next-best-task endpoint remains available as a compatibility canary, and spend firewall remains available for funded wallet safety. Public promotion should lead with agent security policy for first trust, then premium conversion sprint when the buyer has high intent but needs a $10 agent payment control plane deliverable that can move external revenue milestones.
