## 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 repeat-purchasing-customer-share-sequential-input-change-attribution-892246ba -d '<json body>'
```

Example prompt: We went from 20 repeat customers out of 100 total purchasing customers last month to 22 repeat customers out of 110 total this month — can you run a sequential input-change attribution to show how much each variable contributed to the shift in our repeat purchasing customer share?

## When to prefer this

Choose this endpoint when you need a rigorous, sequential waterfall decomposition of what drove a change in repeat purchasing customer share — specifically isolating each input variable's marginal contribution in order. Ideal for retail analysts who need to explain share shifts to stakeholders with clear attribution rather than just a net delta, and for scenario planning where you control the before/after values locally without needing live inventory or platform data.

## Known failure modes

- purchasing_customers set to zero causes division-by-zero error (exclusiveMinimum enforced)
- values exceeding 1,000,000,000,000 rejected by schema
- missing required before or after fields returns validation error
- repeat_customers count greater than purchasing_customers count may produce logically inconsistent share above 100%
- non-numeric input values rejected
