Usage Invoices

Every x402 call you pay for is logged against your payment address (the wallet that signed the payment). This free endpoint aggregates those logs — plus your free-trial usage — into a monthly CSV invoice you can drop into accounting.

Free. No payment, no signup, no API key.

curl "https://api.mekongtradeintel.com/invoice/?address=0xYOUR_PAYMENT_ADDRESS&month=2026-10" -o invoice.csv

Param	Required	Description

What is (and isn't) included

Included: paid calls from every fleet endpoint's paid-calls.log, matched by your payment address (case-insensitive).
Included: free-trial calls keyed to your wallet address (payer:<address> quota keys).
Excluded: failed calls (ok=false) — never billed.
Excluded: internal/FiatDock-routed calls — settled by FiatDock, not x402.
Limitation: trial calls made before wallet-address quotas existed are keyed by IP only and cannot be attributed to an address.
