# Survey Participation Numeric Row Ordering and Adjacent Row Changes

> Survey Participation Numeric Row Ordering and Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Analyzes survey participation data (respondents and invitations) by computing numeric row ordering and detecting adjacent row changes across up to 200 rows.

## 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-numeric-row-ordering-and-adjacent-row-changes-1681fc4a -d '<json body>'
```

Example prompt: I have survey participation records for two course groups — for each date from 2026-10-01 to 2026-10-04, give me the numeric row ordering and adjacent row changes for the respondents field: row-1 group-a 10 respondents 1 invitation, row-2 group-b 20 respondents 2 invitations, row-3 group-a 15 respondents 3 invitations, row-4 group-b 30 respondents 4 invitations.

## When to prefer this

Choose this endpoint when you have up to 200 survey participation records (respondents and/or invitations) and need both a numeric ranking of rows and a sequential change analysis between adjacent rows in a single low-cost call. Ideal for education or research survey datasets organized by date and course group where offline, privacy-preserving local computation is preferred over sending data to a cloud analytics service.

## Known failure modes

- Exceeds 200 row limit — request rejected
- Missing required fields (row_id, course_group, date, respondents, invitations) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema error
- Field value outside allowed numeric range (±1,000,000,000,000) — validation error
- Empty rows array — minItems violation

## How this service works

Survey participation — Numeric row ordering + Adjacent row changes: Numeric row ordering + Adjacent row changes 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

Returns two analytical reports: (1) a numeric row ordering of the supplied survey rows ranked by the selected field (respondents or invitations), and (2) an adjacent row changes report showing the difference between consecutive rows for the selected metric — all computed locally with no external lookups.
