# Compositing Graphs — Equal-Width Histogram + Two-Measure Correlation

> Compositing Graphs — 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 2026-10-17).

Runs two local statistical reports on compositing graph data: an equal-width histogram for a chosen measure and a Pearson-style correlation between node_count and render_seconds.

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 compositing-graphs-equal-width-histogram-two-measure-correlation-2d264d48 -d '<json body>'
```

Example prompt: Analyze my compositing graph records — I have up to 50 rows with node_count and render_seconds fields — run an equal-width histogram on node_count using 10 bins and also compute the correlation between node_count and render_seconds.

## When to prefer this

Choose this endpoint when you have compositing graph pipeline data (node counts and render durations) and need both a distribution histogram and a bivariate correlation in a single low-cost call. It is ideal for VFX, motion graphics, or rendering teams wanting quick statistical insight on job complexity vs render time without any external data lookup or prediction service.

## Known failure modes

- Missing required fields (row_id, date, node_count, render_seconds) causes validation error
- More than 200 rows submitted — exceeds maximum row limit
- bins value outside 1–30 range causes rejection
- Date strings not matching YYYY-MM-DD pattern are rejected
- All-null values for chosen measure may produce degenerate histogram
- Payment not supplied or insufficient USDC causes 402 response

## How this service works

Compositing graphs — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied compositing graphs records (node_count, render_seconds). 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 independent statistical reports: (1) an equal-width histogram showing frequency counts per bin for the selected measure (node_count or render_seconds), and (2) a two-measure correlation analysis quantifying the relationship between node_count and render_seconds across up to 200 supplied rows.
