## 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 coinopselect-batch-net-payment-calculator-c7e1b8b1 -d '<json body>'
```

Example prompt: I have three on-chain payments to settle: address 0xaaa sent 100 to 0xbbb, address 0xccc sent 200 to 0xbbb, and 0xbbb sent 50 to 0xaaa — can you compute the net amounts each party owes or is owed?

## When to prefer this

Choose this endpoint when you need to compute net payment positions across multiple on-chain transactions in a single call, especially when settling multi-party flows on Base. It is preferable to making individual lookups when you have a batch of payments to reconcile at once.

## Known failure modes

- Malformed payment array entries cause validation errors
- Missing required fields (id, to, from, amount) in payment objects result in rejection
- Payment amount not parseable as a number causes computation failure
- Empty payments array returns empty net object
- x402 payment not included or insufficient USDC balance causes 402 Payment Required response

## How this service works

Paid on-chain token, wallet, contract and research data over x402 on Base.

## Output

Returns a JSON object with a 'net' map showing the computed net payment positions across all submitted payment records, and a 'query' field confirming the operation type as 'batch-net'.
