## 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 validator-uptime-record-quality-audit-equal-width-histogram-41f1daca -d '<json body>'
```

Example prompt: Can you run a record quality audit and equal-width histogram on my validator uptime data? I have 4 rows with online_minutes and observed_minutes per day across groups, and I want 5 bins on the online_minutes field.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a histogram distribution analysis on validator uptime records in a single call. It is ideal for pre-reporting data validation, identifying null/corrupt uptime values, and understanding distribution patterns in online or observed minutes — all without requiring external data or live lookups. Best when working with batch uptime datasets of up to 200 rows and needing two complementary analytical reports at low cost.

## Known failure modes

- Rows array empty or exceeds 200 items — validation error returned
- Invalid date format (not YYYY-MM-DD) in any row — schema rejection
- online_minutes or observed_minutes outside allowed numeric range — rejection
- bins value outside 1–30 range — error response
- Missing required row fields (row_id, date, instrument_group) — schema error
- Payment not included or insufficient — x402 payment required response

## How this service works

Validator uptime — Record quality audit + Equal-width histogram: Record quality audit + Equal-width histogram for supplied validator uptime records (online_minutes, observed_minutes). 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 record quality audit identifying issues such as nulls, out-of-range values, or missing required fields across the submitted uptime rows; and (2) an equal-width histogram partitioning the selected field (online_minutes or observed_minutes) into the specified number of bins with frequency counts per bin.
