Machines pay each other now. Someone has to keep the books.
x402ledger Close turns supported machine-payment settlement activity into traceable close workpapers, proposed journals, and exceptions. Outside the money flow, by design.

Outside the money flow. On purpose.
Evidence is only credible when the record-keeper has no hand on the money. These exclusions are permanent — they are the product.
x402ledger never:
- holds funds
- touches private keys
- signs payment authorizations
- submits transactions
- performs settlement or exchange
- makes tax determinations
- lets AI post an entry on its own
PERMANENT EXCLUSIONS · PRODUCT CHARTER · UNCHANGED SINCE DAY ONE
A month-end close for revenue that arrives by the second.
Thousands of machine micropayments become one reviewable close package: register, roll-forward, journals, exceptions, workpapers.
The evidence register
Every settlement event, labeled per evidence leg — settlement, authorization, delivery. A roll-forward demonstrating completeness of supported token events for the scoped wallet across a finalized block range, independently cross-checked.
Proposed journals
Daily summarized journals as validated CSV for supported import templates. Activity is proposed as wallet receipts; revenue classification follows your own approved, versioned policy. Nothing is booked before you approve.
The exceptions queue
Whatever the evidence cannot support lands here — never in your books. Grouped for review, held until disposition. Aggregation is not clearance, and high-risk items are never eligible for bulk approval.
A signature can prove where a payment came from. It takes a method to say what it means.
Cryptography establishes source and integrity — not identity, authority, delivery, or truth. So every figure in an x402ledger close carries one of five evidence labels, applied per leg, with exact criteria. When the evidence is insufficient, the label says so.

Three steps to a close you can stand behind.
A managed, human-reviewed workflow — we do the assembly, you keep the judgment.
Scope the wallet
An authorized representative asserts the wallet-to-entity relationship — entity, address, purpose, effective dates. Corroborated separately by a signed challenge, domain verification, and a timestamped payTo observation, each establishing only its own leg.
We assemble the evidence
Supported settlement activity is ingested once as immutable evidence, cross-checked across a finalized block range, labeled per leg, and valued two ways — native quantity and USD, each with source, version, and timestamp. A stablecoin is never hardcoded at par.
You approve the close
Review the register, the proposed journals, and the exceptions queue. Classification follows your approved policy; whatever fails classification stays unresolved by default. Your books, your approval — every time.
Built for the sell side of the agent economy.
Teams earning x402 revenue
APIs, inference endpoints, data services, agent tools — anyone whose product is paid per call in USDC on Base. If your revenue arrives as thousands of micro-settlements, your month-end deserves better than a block-explorer export.
Accountants serving them
A multi-client console for firms whose clients earn machine-payment revenue. Workpapers with traceable evidence lineage behind every reported figure, designed to support audit and tax-preparation procedures — by people who sit on your side of the table.
Analysis is commoditizing. Soon any model can draft a plausible close from a wallet address. What it cannot fake is the substrate: when intelligence is free, verifiability is the product.
Tamper-evident records. Reproducible outputs — same inputs, same rule versions, same books, every time. An AI-independent posting path. That substrate is what x402ledger is built on, from the first table.
Close your first month on evidence.
We run a small number of hands-on engagements for teams with real x402 settlement activity. Your close, our method — reviewed line by line.
