# Feature Availability Analytics — Numeric Interval Filter + Daily Sum Series

> Feature Availability Analytics — Numeric Interval Filter + 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 2026-10-20).

Runs two local analytical reports on feature availability data: filters rows by a numeric interval and produces a daily sum time series for populated_features or expected_features.

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 feature-availability-analytics-numeric-interval-filter-daily-sum-series-d1fb6e72 -d '<json body>'
```

Example prompt: Can you filter our feature availability records where populated_features is between 0 and 100, and also give me the daily sum series for populated_features? Here are the rows: row-1 on 2026-10-01 group-a with expected=1 populated=10, row-2 on 2026-10-02 group-b expected=2 populated=20, row-3 on 2026-10-03 group-a expected=3 populated=15.

## When to prefer this

Choose this endpoint when you need to perform both an interval-based filter AND a daily sum aggregation on feature availability data (populated vs expected features) in a single paid call. It is best suited for data quality monitoring workflows where you want to identify out-of-range feature counts and understand day-by-day totals without connecting to an external database or running your own analytics engine. Not suitable for real-time lookups, predictions, or datasets larger than 200 rows per call.

## Known failure modes

- Input array is empty or exceeds 200 rows — validation error returned
- Date field does not match YYYY-MM-DD pattern — row rejected
- populated_features or expected_features values outside ±1,000,000,000,000 — schema violation
- minimum greater than maximum — may return empty filter results with no error
- Missing required fields (row_id, date) — request rejected
- Payment of 0.01 USDC not completed — 402 response with payment details

## How this service works

Feature availability — Numeric interval filter + Daily sum series: Numeric interval filter + Daily sum series for supplied feature availability records (populated_features, expected_features). 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 interval filter report listing rows where the selected field falls within the specified minimum–maximum range, and (2) a daily sum time series aggregating the selected field (populated_features or expected_features) by date. Up to 200 input rows supported per call.
