# Waste Monitoring Equal-Width Histogram

> Waste Monitoring 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 2026-10-15).

Computes an equal-width histogram over collected_kg or recycled_kg values from waste monitoring records, returning bin counts and ranges.

## 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 waste-monitoring-equal-width-histogram-bcd9e067 -d '<json body>'
```

Example prompt: Can you generate an equal-width histogram of the collected_kg values from my waste records using 10 bins? I have data for materials like 'plastics' and 'organics' collected between 2025-01-01 and 2025-03-31.

## When to prefer this

Choose this endpoint when you need a fast, local equal-width histogram specifically over waste monitoring numeric fields (collected_kg or recycled_kg) without requiring external data enrichment or forecasting. It is ideal for quick distributional summaries of up to 200 waste records where you control bin count and field selection. Prefer this over general statistics endpoints when you specifically want binned frequency distributions in the waste/recycling domain.

## Known failure modes

- Fewer than 1 or more than 200 rows submitted — request rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- bins value outside 1–30 range returns validation error
- field value not in enum ['collected_kg','recycled_kg'] causes rejection
- All values null for selected field results in degenerate or empty histogram
- Malformed row objects missing required fields (row_id, material, date) cause errors

## How this service works

Waste monitoring - Equal-width histogram: Equal-width histogram for Waste monitoring. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded equal-width histogram deliverable.

## Output

A bounded equal-width histogram deliverable containing bin definitions (lower and upper boundaries, bin width) and the frequency count of records falling into each bin, computed locally from up to 200 typed waste records without external enrichment.
