## 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 token-buy-receipt-shortfall-batch-calculation-bffdb097 -d '<json body>'
```

Example prompt: Can you calculate the token buy receipt shortfalls for these purchases: I expected 1000 tokens but received 950, expected 1100 but received 1045, and expected 500 but received 480?

## When to prefer this

Use this endpoint when you need to deterministically calculate token quantity shortfalls across multiple token purchase records in a single API call. It is best suited for auditing, reconciliation, or verification workflows where you have a list of expected vs actual token receipt pairs and want a structured batch report without needing a live blockchain scan or trade recommendation.

## Known failure modes

- Missing required fields (expected_tokens or actual_tokens) returns validation error
- expected_tokens set to 0 or excluded violates exclusiveMinimum constraint
- Batch exceeds 200 rows returns schema validation error
- Non-numeric token values cause input rejection
- Payment not processed results in 402 response

## How this service works

Deterministic calculation or caller-threshold verdict, not a live scan, safety proof or trade recommendation. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one bounded batch calculation report.

## Output

A bounded batch calculation report listing the shortfall (difference between expected_tokens and actual_tokens) for each supplied row, along with any threshold-based verdict if applicable. Returns up to 200 row results deterministically based on the supplied input pairs.
