# Compositing Graphs — Equal-Width Histogram + Secondary-Measure Weighted Mean

> Compositing Graphs — Equal-Width Histogram + Secondary-Measure Weighted Mean 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).

Generates two analytical reports for compositing graph records: an equal-width histogram over a chosen field and a secondary-measure weighted mean, for up to 200 rows.

## 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-secondary-measure-weighted-25a48c25 -d '<json body>'
```

Example prompt: Analyze my compositing graph records — I have 4 rows with node counts 10, 20, 15, 30 for groups a and b on dates 2026-10-01 through 2026-10-04, with render seconds 1, 2, 3, 4. Give me an equal-width histogram of node_count using 5 bins plus the secondary weighted mean.

## When to prefer this

Choose this endpoint when you need simultaneous histogram distribution analysis and weighted mean computation on compositing graph data (node_count and render_seconds) in a single low-cost call. Ideal for media/VFX pipelines auditing render performance across asset groups. Prefer this over generic statistics APIs when your data maps directly to the compositing graph schema (row_id, asset_group, date, node_count, render_seconds).

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes row-level validation failure
- Missing required fields (row_id, asset_group, date, node_count, render_seconds) causes schema error
- bins value outside 1–30 range is rejected
- Null values in numeric fields may affect histogram bin calculation
- field enum value not matching 'node_count' or 'render_seconds' causes error
- Insufficient USDC balance for x402 payment fails the request

## How this service works

Compositing graphs — Equal-width histogram + Secondary-measure weighted mean: Equal-width histogram + Secondary-measure weighted mean 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 analytical reports: (1) an equal-width histogram over the specified field (node_count or render_seconds) divided into the requested number of bins, showing frequency/count per bin; (2) a secondary-measure weighted mean computed from the supplied compositing graph records. Both reports are computed locally from the supplied data with no external lookups.
