# Survey Response Weights — Daily Sum Series + Keyed Dataset Comparison

> Survey Response Weights — Daily Sum Series + Keyed Dataset Comparison 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).

Runs two local analytical reports on survey response weight data: a daily sum time series and a keyed row-by-row comparison between two supplied datasets, for 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-response-weights-daily-sum-series-keyed-dataset-comparison-d262bfcc -d '<json body>'
```

Example prompt: I have two sets of survey records — each row has a row_id, region, date, response_value, and sample_weight — can you run a daily sum series on the response_value field and then compare the two datasets keyed by row ID to flag any differences? Here's my primary dataset of 4 rows and a comparison dataset with slightly different values.

## When to prefer this

Choose this endpoint when you need both a temporal aggregation (daily sums) and a row-keyed comparison between two survey datasets in a single API call at low cost. It is well-suited for survey analysts or economists who supply their own data and want fast, self-contained computation without any external data lookup or live prediction. It is not appropriate when you need forecasts, real-time data, more than 200 rows, or reports beyond daily sum series and keyed comparison.

## Known failure modes

- Missing required fields (row_id, region, date, response_value, sample_weight) cause validation errors
- Exceeding 200 rows returns an input size error
- Malformed date strings not matching YYYY-MM-DD pattern cause schema rejection
- Null values in response_value or sample_weight may be handled as zero or skipped depending on engine behavior
- Mismatched row_ids between primary and comparison datasets may produce empty or partial keyed comparison results
- Payment failure (insufficient USDC) prevents report generation

## How this service works

Survey response weights — Daily sum series + Keyed dataset comparison: Daily sum series + Keyed dataset comparison for supplied survey response weights records (response_value, sample_weight). 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 independent analytical reports: (1) a daily sum series showing the aggregated selected field (response_value or sample_weight) totaled per date across all supplied rows, and (2) a keyed dataset comparison that matches rows from the primary and secondary datasets by row_id and highlights value differences. Both reports are computed locally using shared analytical engines with no external data lookups.
