# Community Survey String Normalisation and Secondary-Measure Weighted Mean

> Community Survey String Normalisation and Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-11-02).

Normalises string fields and computes a secondary-measure weighted mean across up to 200 community survey rows (response_count, invitation_count), returning 2 analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 community-survey-string-normalisation-and-secondary-measure-weighted-ed5d08a9 -d '<json body>'
```

Example prompt: Can you run string normalisation and a secondary-measure weighted mean on these 4 community survey rows — the field I want to analyze is response_count, with channel groups group-a and group-b across dates 2026-10-01 to 2026-10-04, and give me both reports?

## When to prefer this

Choose this endpoint when you need both string normalisation and weighted mean computation on community survey data (response_count, invitation_count) in a single $0.01 call covering up to 200 rows and 2 reports, without requiring any external lookup or live data source.

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems limit
- Missing required fields (row_id, channel_group, date, response_count, invitation_count) — validation error returned
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Null numeric values for both response_count and invitation_count may reduce weighted mean reliability
- Payment not provided or insufficient USDC — x402 payment required error

## How this service works

Community survey — String normalisation + Secondary-measure weighted mean: String normalisation + Secondary-measure weighted mean for supplied community survey records (response_count, invitation_count). 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 analytical reports per call: (1) a string normalisation report over the channel_group and other string fields in the supplied rows, and (2) a secondary-measure weighted mean of the chosen field (response_count or invitation_count) across up to 200 community survey records grouped by the available dimensions.
