## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability invoice-duplicate-overpayment-recovery-analyzer-55c1dfac -d '<json body>'
```

Example prompt: I think we overpaid vendor V1 on invoice INV-100 — we have two payments of $100 each plus a $20 credit applied. Can you run the invoice duplicate recovery analysis and tell me if we're owed a refund and how much?

## When to prefer this

Use this endpoint when you need to programmatically detect overpayments, duplicate payments, or misapplied credits across vendor invoices and need a structured evidence bundle suitable for initiating a credit recovery request. It is specifically suited to accounts-payable reconciliation workflows where multiple payments and credits may apply to a single invoice. Prefer this over manual spreadsheet reconciliation or generic accounting APIs when you need auditability and a machine-readable evidence bundle with per-invoice breakdowns.

## Known failure modes

- Mismatched currency codes across payments and invoices may cause computation errors
- Missing or malformed invoice/payment IDs result in orphan records rather than matched analysis
- Incorrect minor unit digit specification leads to wrong amount calculations
- Payments referencing non-existent invoices returned as orphan_payments with no credit request generated
- Invalid or missing vendor_id may result in empty or unlinked result sets

## How this service works

Customer-input analysis tools with per-call x402 v2 USDC payments on Base. Discovery and examples are free.

## Output

Returns a JSON object with per-invoice summaries including gross, net, credited, expected, overpaid, and outstanding amounts in both decimal and minor units; a list of credit requests with reason codes and full evidence bundles (linked payment IDs, credit IDs, invoice details); lists of orphan payments, orphan credits, and duplicate imports; and a disclaimer clarifying this is a computed evidence bundle, not a legal or financial determination.
