# Project Risks Base-100 Series and Equal-Width Histogram

> Project Risks Base-100 Series and Equal-Width Histogram 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).

Generates a Base-100 indexed time series and an equal-width histogram for project risk data (open_items and mitigated_items) supplied by the caller.

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 project-risks-base-100-series-and-equal-width-histogram-ea895d04 -d '<json body>'
```

Example prompt: Take these 4 project risk records for group-a and group-b from October 2026 and give me a Base-100 series indexed from row 0 plus an equal-width histogram with 5 bins for the open_items field: row-1 2026-10-01 group-a open=10 mitigated=1, row-2 2026-10-02 group-b open=20 mitigated=2, row-3 2026-10-03 group-a open=15 mitigated=3, row-4 2026-10-04 group-b open=30 mitigated=4.

## When to prefer this

Choose this endpoint when you have project risk records with open and mitigated item counts and need both a normalized baseline index and a frequency distribution histogram in a single call for up to 200 rows. It is ideal for offline or batch analytical workflows where no live data lookup, prediction, or external action is needed and cost efficiency matters (two reports per $0.01).

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — validation error
- base_index references a row index outside the submitted row count — error
- bins value outside 1–30 range — validation error
- Missing required fields (row_id, team_group, date, open_items, mitigated_items) in any row — schema validation failure
- Date values not matching YYYY-MM-DD pattern — validation error
- All values for selected field are null — histogram and index cannot be computed

## How this service works

Project risks — Base-100 series + Equal-width histogram: Base-100 series + Equal-width histogram for supplied project risks records (open_items, mitigated_items). 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 project risk records: (1) a Base-100 indexed time series normalizing the selected field (open_items or mitigated_items) relative to the specified base_index row, and (2) an equal-width histogram dividing the selected field's value range into the specified number of bins with frequency counts. Both reports are computed locally on the submitted data with no external lookups.
