How this service works
GO-TO product for funded agents: Daily Agent Signal (POST /v1/signal_latest $0.03, /v1/signal_history $0.10, /v1/signal_delta $0.05). Signal is the flagship; supporting/legacy routes are demoted. Archive honesty: archive_day_count=6 — 6 stored dates from 2026-09-19 through 2026-09-27. Intraday revisions do not add archive days. Unpaid calls return HTTP 402. USDC on Base. Free discovery: /, /agents.md, /llms.txt, /skill.md, /.well-known/x402.json, /.well-known/mcp.json, /openapi.json.
Output
Returns a JSON object with at minimum an 'ok' boolean status, a 'brand' string, and a 'product' string, along with invoice aging data indicating the age and status of outstanding invoices. Unpaid or unauthenticated calls return HTTP 402.
Example use cases
Accounts receivable aging check
“I need to see the current aging breakdown of all our outstanding invoices — can you fetch the invoice aging report and tell me which ones are past 30, 60, and 90 days?”
Financial reconciliation for agent
“Pull the invoice aging data so I can reconcile our books — I want to know the status and age of all unpaid invoices right now.”
Overdue invoice monitoring
“Check the invoice aging report and flag anything that's overdue — I need to know which invoices are getting stale before end of quarter.”

Endpoint
POSThttps://draconic21-x402-api.onrender.com/v1/invoice_aging?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need invoice aging data in the context of an x402-enabled agent that pays per call in USDC on Base. Best suited for funded autonomous agents that need lightweight, on-demand invoice aging lookups without a full ERP integration. Not suitable for multi-day historical trend analysis given the single-day archive depth.
Side effects
- HTTP 402 returned if USDC payment on Base is not provided or insufficient
- Empty or malformed request body may result in validation errors
- Single-day archive depth means historical aging data is limited to one day (2026-09-19)
- Service hosted on Render free tier may have cold-start latency or downtime
