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 JSON object with an audit_id, a recorded boolean, a reason string classifying the payment (e.g. 'small-amount exception candidate'), and boolean flags indicating whether an invoice, bookkeeping entry, or monthly summary is required for this transaction.
Example use cases
Example prompt
“Record a payment of 10.50 USDC on the Base network for agent-qa-test-001 — the transaction hash is 0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef, the purpose was api-request-processing, and the tax-included JPY amount is 1155.00.”
Technical details
Endpoint
POSThttps://agent-budget-guard.onrender.com/api/record-paymentWhen to prefer
Use this endpoint when an AI agent has completed a USDC payment on Base and needs to log the transaction for governance, compliance, or JPY tax reporting. Ideal for autonomous agent workflows that require per-payment audit trails, bookkeeping classification, and monthly expense summaries rather than just checking balances.
Side effects
- Missing required fields (amount, tx_hash, agent_id) return validation errors
- Invalid or malformed transaction hash may cause recording failure
- Network value not matching supported chains may be rejected
- Duplicate tx_hash submissions may create redundant audit records
- Service unavailability on Render.com free tier may cause timeouts
