# Market Survey Observations — Category Frequencies & Daily Sum Series

> Market Survey Observations — Category Frequencies & Daily Sum Series 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).

Analyzes up to 200 market survey observation rows to produce two reports: category frequency breakdown by company group and a daily sum time series for respondent_count or sample_weight.

## 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-category-frequencies-daily-sum-series-5b1e3b94 -d '<json body>'
```

Example prompt: I have 150 market survey rows with fields for company_group, date, respondent_count, and sample_weight — can you give me both a category frequency breakdown by group and a daily sum time series for respondent_count across all dates?

## When to prefer this

Choose this endpoint when you have raw market survey observation records and need two quick summary reports — category-level frequency distributions and day-by-day aggregated totals — in a single low-cost call without needing live data, external lookups, or predictions. Best suited for batches up to 200 rows where both a group breakdown and a temporal series are needed simultaneously.

## Known failure modes

- Rows array is empty or missing — minimum 1 row required
- More than 200 rows supplied — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) — pattern validation fails
- Missing required row fields (row_id, company_group, date) — schema validation error
- Numeric fields out of allowed range (±1,000,000,000,000)
- Invalid field enum value — must be 'respondent_count' or 'sample_weight'

## How this service works

Market survey observations — Category frequencies + Daily sum series: Category frequencies + Daily sum series 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

Two analytical reports: (1) a category frequency table showing how observations distribute across company_group values, and (2) a daily sum time series aggregating the selected field (respondent_count or sample_weight) by date — both computed locally from the supplied rows with no external lookups.
