## 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 marketing-contribution-return-batch-calculator-476b81b2 -d '<json body>'
```

Example prompt: I have 5 campaigns I want to evaluate — can you batch-calculate the marketing contribution return for each one? Campaign 1: spend $5,000, attributed contribution $8,000; Campaign 2: spend $5,500, contribution $8,800; Campaign 3: spend $3,000, contribution $4,500; Campaign 4: spend $10,000, contribution $12,000; Campaign 5: spend $7,200, contribution $9,600.

## When to prefer this

Choose this endpoint when you need to compute marketing contribution return for multiple records in a single call (up to 200 rows), especially when you want invalid-row detection included in the same response. Prefer this over a single-record calculator when processing campaign portfolios, regional datasets, or exported spreadsheets. Best when you only have marketing spend and attributed contribution figures and need structured output with formula and unit documentation included.

## Known failure modes

- Rows missing required fields (marketing_spend or attributed_contribution) flagged as invalid
- marketing_spend of 0 or negative rejected due to exclusiveMinimum constraint
- Values exceeding 1,000,000,000,000 rejected as out of range
- Batch exceeding 200 rows rejected
- Malformed JSON input returns error
- Payment of 0.01 USDC not completed results in 402 response
