How this service works
Pay-per-request governance APIs for AI agents using x402. Check budgets, log payments, classify invoices, and generate audit-ready spending records. Built for autonomous agents, USDC/Base payments, and JPY/JPYC reporting workflows.
Output
Returns a boolean confirming the transaction was recorded, the agent's running total spend for today and this month in USDC, and a recommended next API call with name, URL, rationale, expected improvement, and price in USDC.
Example use cases
Example prompt
“Record a $0.01 USDC payment that agent 'agent-007' just made to https://some-api.example.com for a 'data-lookup' action, with a daily limit of $1.00 USDC, and tell me the total spent today and this month.”
Technical details
Endpoint
POSThttps://agent-budget-guard.onrender.com/api/budget/recordWhen to prefer
Use this endpoint after each pay-per-request API call to maintain a running audit log of agent spending. Ideal when your agent operates on USDC/Base via x402 and needs cumulative daily/monthly totals for governance, budget enforcement, or JPY/JPYC compliance reporting. Prefer this over generic logging when you also want AI-driven next-action recommendations.

- Invalid currency value returns 400 bad request
- Service unavailable on Render cold start returns 503 or timeout
