# Competitor Supplied Prices — Equal-Width Histogram + Two-Measure Correlation

> Competitor Supplied Prices — 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 2026-10-15).

Computes an equal-width histogram and a two-measure correlation report for up to 200 rows of competitor price data (list_price, package_quantity) using local analytical engines.

## 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 competitor-supplied-prices-equal-width-histogram-two-measure-c74d5d7a -d '<json body>'
```

Example prompt: I have competitor pricing records with list_price and package_quantity for two company groups — can you run a histogram with 10 bins on the list_price field and also compute the two-measure correlation between list_price and package_quantity for all 150 rows?

## When to prefer this

Choose this endpoint when you have pre-collected competitor pricing data (list_price, package_quantity) as structured rows and need both a histogram distribution view and a correlation measure in a single call, without needing live market lookups or external data enrichment. Ideal for batch offline analysis of up to 200 records at low cost ($0.01 USDC for both reports).

## Known failure modes

- More than 200 rows submitted — request rejected due to maxItems limit
- Missing required fields (row_id, company_group, date, list_price, or package_quantity) cause validation errors
- Invalid date format (non-YYYY-MM-DD) triggers pattern validation failure
- bins value outside 1–30 range causes schema rejection
- All null values for the selected field may produce degenerate histogram output
- Malformed JSON body returns 400-level error

## How this service works

Competitor supplied prices — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied competitor supplied prices records (list_price, package_quantity). 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) an equal-width histogram showing bin boundaries and counts for the selected field (list_price or package_quantity) across up to 200 input rows, and (2) a two-measure correlation report quantifying the statistical relationship between list_price and package_quantity. No external data is fetched; computation is performed locally on the supplied dataset.
