400860 Agent Spend Firewall
api.400860.xyz
x402 pay-per-use API for AI agents and API sellers. It helps agents decide whether they may spend before signing, verify paid x402 endpoints, and generate spend policy, prepay checks, receipt validation, anomaly rules, and checkout repair guidance. No API key; paid capabilities return HTTP 402/x402 payment requirements.
