## 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-one-input-sensitivity-table-672d0857 -d '<json body>'
```

Example prompt: Run a one-input sensitivity table for marketing contribution return, varying attributed_contribution across [6000, 7000, 8000, 9000, 10000] while holding marketing_spend fixed at 5000, and show me the results with the formula and units.

## When to prefer this

Choose this endpoint when you need a bounded, single-variable sensitivity analysis specifically for marketing contribution return — ideal for scenario planning, budget stress testing, or understanding how one marketing input drives return while the other is held fixed. Prefer this over manual calculation when you need up to 50 data points in one call with formula and units included. Not suitable for two-variable sensitivity, live market data, or financial advice.

## Known failure modes

- More than 50 values supplied in the values array — request rejected
- marketing_spend set to zero or negative — violates exclusiveMinimum constraint
- Missing required baseline fields (attributed_contribution or marketing_spend) — validation error
- Values outside the allowed range of ±1,000,000,000,000 — rejected
- Invalid field enum value (not attributed_contribution or marketing_spend) — error returned
- Payment failure or insufficient USDC balance — 402 response, no result returned
