## 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 margin-of-safety-batch-calculator-4482df5a -d '<json body>'
```

Example prompt: Can you calculate the margin of safety for my sales data in batch? I have 5 records: actual sales of 10000, 15000, 12000, 9000, and 20000 against break-even sales of 7000, 11000, 8500, 9500, and 14000 respectively — and flag any invalid rows.

## When to prefer this

Choose this endpoint when you need to compute margin of safety for multiple records in a single API call (up to 200), want the formula and units documented in the response, and need invalid row detection built in. Prefer it over single-record calculators when processing bulk financial datasets, validating data quality across many rows, or generating batch reports for managerial accounting purposes. Not suitable when you need live market data, financial advice, or trade execution.

## Known failure modes

- Empty rows array or missing required fields (actual_sales or break_even_sales) returns validation error
- actual_sales of zero triggers exclusiveMinimum violation
- Exceeding 200 rows returns a batch size limit error
- Non-numeric values in sales fields cause schema validation failure
- break_even_sales exceeding actual_sales returns a valid but negative or zero margin result, flagged as invalid
