# Market Survey Observations — Base-100 Series + Keyed Dataset Comparison

> Market Survey Observations — Base-100 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 2026-10-15).

Runs two analytical reports (Base-100 indexed time series and keyed dataset comparison) on supplied market survey observation data for respondent_count or sample_weight fields.

## 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 market-survey-observations-base-100-series-keyed-dataset-comparison-92669470 -d '<json body>'
```

Example prompt: Can you run a Base-100 series and keyed dataset comparison on these two sets of market survey observations — up to 200 rows each with respondent_count, sample_weight, company_group, and date — analyzing the respondent_count field and show me how the two datasets differ?

## When to prefer this

Choose this endpoint when you need to simultaneously produce a Base-100 indexed time series AND a keyed dataset comparison for market survey observations (respondent_count or sample_weight) from two supplied datasets of up to 200 rows each, without requiring any external data lookup or live data fetch. It is especially useful when comparing two survey waves or panels by company group over time. Not suitable for real-time data, predictions, or datasets exceeding 200 rows.

## Known failure modes

- Exceeds 200-row limit for either dataset — request rejected
- Missing required fields (row_id, company_group, date, respondent_count, sample_weight) — validation error
- Invalid date format (non-YYYY-MM-DD) — schema validation failure
- Field selector not one of 'respondent_count' or 'sample_weight' — enum validation error
- Null values in selected metric field may produce incomplete index calculations
- Mismatched row_ids between primary and other dataset reduce keyed comparison coverage

## How this service works

Market survey observations — Base-100 series + Keyed dataset comparison: Base-100 series + Keyed dataset comparison for supplied market survey observations records (respondent_count, 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 analytical reports for the supplied market survey data: (1) a Base-100 indexed time series showing how the selected metric (respondent_count or sample_weight) trends relative to a baseline across dates and company groups, and (2) a keyed dataset comparison that aligns rows from the primary and secondary datasets by key to highlight differences in the selected metric. All computation is performed locally on the submitted data with no external lookups.
