# Local Event Calendars — Record Quality Audit + Exact Row Deduplication + Equal-Width Histogram

> Local Event Calendars — Record Quality Audit + Exact Row Deduplication + 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 2026-11-02).

Runs three analytical reports (record quality audit, exact row deduplication, and equal-width histogram) on up to 200 rows of local event calendar data containing listed_events and updated_events fields.

## 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 local-event-calendars-record-quality-audit-exact-row-deduplication-eaf6e882 -d '<json body>'
```

Example prompt: Can you audit the quality of my local event calendar data, remove exact duplicate rows, and generate a 5-bin histogram on the listed_events field? I have about 50 rows with date, channel_group, listed_events, and updated_events columns.

## When to prefer this

Choose this endpoint when you need three distinct data profiling reports — quality audit, deduplication, and histogram — on local event calendar data in a single paid call. It is best suited for small-to-medium datasets up to 200 rows where you want offline, deterministic analysis with no external lookups or predictions. Prefer this over generic analytics services when your data specifically contains listed_events and updated_events metrics per channel group and date, and you want a bundled, cost-efficient ($0.01 USDC) three-report output.

## Known failure modes

- Rows array is empty or exceeds 200 items — rejected with validation error
- Invalid date format (not YYYY-MM-DD) in any row — schema validation failure
- Missing required fields (row_id, channel_group, date, listed_events, updated_events) — request rejected
- bins value outside 1–30 range — validation error
- field value not one of listed_events or updated_events — enum validation error
- Payment of 0.01 USDC not fulfilled — 402 Payment Required response

## How this service works

Local event calendars — Record quality audit + Exact row deduplication + Equal-width histogram: Record quality audit + Exact row deduplication + Equal-width histogram for supplied local event calendars records (listed_events, updated_events). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent analytical reports: (1) a record quality audit flagging issues such as nulls, out-of-range values, and malformed fields across the submitted rows; (2) an exact row deduplication report identifying and removing identical rows from the dataset; and (3) an equal-width histogram partitioning values of the selected field (listed_events or updated_events) into the specified number of bins with counts per bin. All analysis is performed locally on the supplied data with no external lookups.
