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 business-event-participation-record-quality-audit-equal-width-histogram-d4334fed -d '<json body>'
```

Example prompt: Can you audit the quality of these 4 business event participation records and give me an equal-width histogram with 5 bins for attendee_count? The records are: row-1 on 2026-10-01, group-a, 10 attendees, 1 company; row-2 on 2026-10-02, group-b, 20 attendees, 2 companies; row-3 on 2026-10-03, group-a, 15 attendees, 3 companies; row-4 on 2026-10-04, group-b, 30 attendees, 4 companies.

## When to prefer this

Choose this endpoint when you need simultaneous data quality auditing and distribution analysis on business event participation data (attendee or company counts) without making any external API calls or lookups. Ideal for lightweight, batch data profiling tasks on up to 200 rows at low cost ($0.01 USDC for both reports). Prefer over general-purpose analytics tools when you specifically need the record quality audit + histogram combination on event participation schemas.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, company_group, date, attendee_count, company_count) causes a schema validation failure
- Invalid date format (not YYYY-MM-DD) triggers a pattern mismatch error
- Bin count outside 1–30 range is rejected
- Numeric values outside ±1,000,000,000,000 are rejected
- Payment failure or insufficient USDC balance prevents processing

## How this service works

Business event participation — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied business event participation records (attendee_count, company_count). 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 record quality audit identifying completeness, validity, and anomaly issues across the submitted rows for the specified fields; (2) an equal-width histogram showing frequency distribution of the selected field (attendee_count or company_count) across the configurable number of bins (1–30). Both reports are computed locally without external lookups.
