## 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 survey-participation-record-quality-audit-secondary-measure-weighted-b67b9e54 -d '<json body>'
```

Example prompt: Can you run a quality audit and weighted mean analysis on these survey participation records for our course groups? I have rows with respondents and invitations from 2026-10-01 through 2026-10-04 for group-a and group-b — use respondents as the primary field.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a weighted mean statistic on survey participation data (respondents/invitations) in a single cost-effective call. Ideal when you have up to 200 rows of education or survey data and want offline, local computation without any external data enrichment or prediction. Best suited for pre-analysis QA pipelines or reporting workflows where data integrity and summary statistics are needed together.

## Known failure modes

- Exceeding 200 rows results in rejection or truncation
- Missing required fields (row_id, course_group, date, respondents, invitations) cause validation errors
- Malformed date strings not matching YYYY-MM-DD pattern cause row-level errors
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) are rejected
- Empty rows array returns an error
- Invalid field enum value (not 'respondents' or 'invitations') causes request failure

## How this service works

Survey participation — Record quality audit + Secondary-measure weighted mean: Record quality audit + Secondary-measure weighted mean for supplied survey participation records (respondents, invitations). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Two independent analytical reports: (1) a record quality audit flagging data issues such as missing values, out-of-range numbers, or malformed dates across the submitted survey participation rows; and (2) a weighted mean calculation for the selected field (respondents or invitations), computed across all valid rows. Both reports are generated locally from the supplied data with no external lookups.
