## 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-threshold-classifier-2baf2601 -d '<json body>'
```

Example prompt: Classify these four campaigns' marketing contribution returns against a threshold of 0 to 100: campaign A spent 5000 and contributed 8000, campaign B spent 5500 and contributed 8800, campaign C spent 6000 and contributed 7000, campaign D spent 4000 and contributed 9000 — give me a full report with formula and units.

## When to prefer this

Choose this endpoint when you need to batch-classify multiple pre-calculated or raw marketing contribution return figures against a fixed inclusive numeric range and receive a structured JSON report with formula and unit metadata. It is ideal for auditing campaign portfolios, automating threshold-based segmentation of MCR values, or feeding classification results into downstream reporting pipelines. Prefer it over general-purpose calculators when you specifically need the bounded threshold classification mode (not regression, trend, or other analysis modes) for the marketing contribution return metric.

## Known failure modes

- Fewer than 2 rows supplied — minimum item count not met
- marketing_spend is zero or negative — exclusiveMinimum violation
- Row count exceeds 200 — maxItems constraint
- Lower or upper bound outside allowed numeric range — schema validation error
- Missing required fields attributed_contribution or marketing_spend in any row
- Malformed JSON payload returns 400 error

## How this service works

Marketing contribution return - Threshold classification: Classify up to 200 calculated values against supplied inclusive bounds. 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 threshold classification report.

## Output

A JSON object containing the threshold classification result for each row (whether the calculated marketing contribution return falls within the inclusive lower and upper bounds), plus the formula used to compute MCR, the units applied, and any stated limitations of the calculation.
