# Data Ingestion Batches — Equal-Width Histogram + Two-Measure Correlation

> Data Ingestion Batches — Equal-Width Histogram + Two-Measure Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-21).

Computes an equal-width histogram and a two-measure Pearson/Spearman correlation for supplied data ingestion batch records (received_rows, accepted_rows) in a single call.

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 data-ingestion-batches-equal-width-histogram-two-measure-correlation-4b250926 -d '<json body>'
```

Example prompt: Can you run a histogram and correlation analysis on these data ingestion batch records — use 10 bins on the received_rows field and also calculate the correlation between received_rows and accepted_rows? Here are up to 50 rows with row_id, dataset_group, date, received_rows, and accepted_rows.

## When to prefer this

Choose this endpoint when you need both a distribution view (histogram) and a bivariate relationship measure (correlation) for data ingestion batch records in a single cheap call ($0.01). Ideal for pipelines where you want to audit received vs accepted row counts without setting up local analytics infrastructure. Best when your dataset is 200 rows or fewer and you want two complementary statistical reports bundled together.

## Known failure modes

- Rows array is empty or missing — returns validation error
- More than 200 rows supplied — rejected per maxItems constraint
- bins value exceeds 30 or is below 1 — rejected per schema bounds
- Required fields (row_id, date) missing from one or more row objects — validation failure
- Numeric values outside allowed range (±1 trillion) — rejected
- Non-date-format string in date field — pattern validation failure

## How this service works

Data ingestion batches — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied data ingestion batches records (received_rows, accepted_rows). 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 statistical reports: (1) an equal-width histogram showing bin edges and counts for the chosen field (received_rows or accepted_rows), and (2) a two-measure correlation report between received_rows and accepted_rows — all computed locally with no external data lookups.
