## 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 novapath-survey-audit-6ecc7ec9 -d '<json body>'
```

Example prompt: Can you audit these 3 survey items for me — I have 450 answered and 50 skipped for a single-choice question with category counts of [200, 150, 100] and reported percents of [44.4, 33.3, 22.2], and I want to check if the totals and percentages are consistent? The overall sample is 500 respondents and source versions are in agreement.

## When to prefer this

Choose this endpoint when you need to programmatically validate survey aggregate data for statistical consistency errors — especially denominator mistakes, multi-select percentage overflows, and source version mismatches — without exposing respondent-level records. Ideal for research teams doing pre-publication QA, data journalists checking survey reports, or automated pipelines auditing survey outputs before downstream analysis.

## Known failure modes

- Exceeding 10 items in the items array returns a validation error
- Mismatched array lengths between categoryCounts and reportedPercents cause rejection
- answered + skipped values inconsistent with sampleRows may trigger a warning or error
- Null values in reportedPercents for required positions may reduce audit coverage
- Non-numeric or out-of-range values in category counts cause schema validation failure

## How this service works

Audit up to 10 survey items for denominator errors, incompatible source totals and multi-select percentage mistakes. Returns corrections and a review queue from aggregate inputs; no respondent records.

## Output

Returns a list of corrections identifying specific errors per survey item (denominator mismatches, percentage sum errors, incompatible source totals) along with a prioritized review queue of flagged items. No individual respondent records are included — all outputs are based on aggregate inputs.
