## 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-target-gap-calculator-0b8f8bac -d '<json body>'
```

Example prompt: My marketing spend was $5,000 and the attributed contribution was $8,000 — can you calculate the marketing contribution return and tell me how far that is from my target of 175?

## When to prefer this

Choose this endpoint when you need a bounded, formula-based gap analysis between a calculated marketing contribution return metric and a specific numeric target you supply — and you want the formula, units, and limitations returned alongside the result. Prefer it over generic calculators when you already have marketing spend and attributed contribution figures and want a structured JSON report. Do not use it for financial advice, trade execution, or setting targets automatically.

## Known failure modes

- Missing required fields (marketing_spend or attributed_contribution) returns a validation error
- marketing_spend of zero or below triggers exclusiveMinimum validation failure
- Values exceeding the maximum bounds (1e12 for spend/contribution, 1e18 for target) are rejected
- Non-numeric input for any field causes a schema validation error
- No live data or external feeds — results are purely formula-based on supplied figures

## How this service works

Marketing contribution return - Target gap calculation: Measure one calculated value against a supplied numeric target; no recommendation or target setting. Metric: Marketing contribution return. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded target gap calculation report.

## Output

A JSON object containing the calculated marketing contribution return value, the numerical gap between that value and the supplied target, the formula used to derive the metric, the units the result is expressed in, and a limitations statement about the calculation.
