# Marketing Contribution Return – Two-Input Scenario Grid

> Marketing Contribution Return – Two-Input Scenario Grid is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Calculates up to 100 combinations of two input variables (attributed_contribution and/or marketing_spend) to produce a scenario grid for marketing contribution return analysis.

## 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-two-input-scenario-grid-dea3b3f9 -d '<json body>'
```

Example prompt: Run a two-input scenario grid for marketing contribution return with a baseline of $5,000 marketing spend and $8,000 attributed contribution — vary marketing_spend across [4000, 4500, 5000, 5500, 6000] on one axis and attributed_contribution across [7000, 7500, 8000, 8500, 9000] on the other, and show me all valid combinations.

## When to prefer this

Choose this endpoint when you need to explore how marketing contribution return responds to simultaneous variation in two distinct input parameters (attributed contribution and/or marketing spend), producing a full combination matrix. Prefer this over single-input sensitivity endpoints when you need to understand two-variable interaction effects. Suitable for scenario planning, budget stress testing, and contribution return forecasting across a defined input space.

## Known failure modes

- field_x and field_y set to the same enum value (no two-distinct-input grid possible)
- values_x or values_y arrays empty or exceeding 10 items each
- baseline values missing required fields (attributed_contribution or marketing_spend)
- marketing_spend baseline set to zero or negative (excluded by exclusiveMinimum)
- payment not included or insufficient (requires 0.01 USDC via x402)
- input values outside allowed range (±1,000,000,000,000)

## How this service works

Marketing contribution return - Two-input scenario grid: Calculate up to 100 combinations of two distinct supplied input fields, with invalid combinations reported. 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 two-input scenario grid report.

## Output

Returns a JSON object containing: a grid of up to 100 marketing contribution return values for all valid (field_x, field_y) combinations, the formula used, units, any invalid combinations with explanations, and applicable limitations.
