# Compositing Graphs — Category Frequencies + Equal-Width Histogram

> Compositing Graphs — Category Frequencies + 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 2026-10-17).

Runs two local analytical reports on compositing graph records: a category frequency breakdown and an equal-width histogram for either node_count or render_seconds, over up to 200 rows.

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-category-frequencies-equal-width-histogram-68c57aa7 -d '<json body>'
```

Example prompt: Analyze my compositing graph records — here are 50 rows with node_count and render_seconds per asset_group and date — give me category frequencies by asset_group and an equal-width histogram of render_seconds using 8 bins.

## When to prefer this

Choose this endpoint when you have compositing graph records (with node_count and render_seconds) and need both a categorical frequency breakdown and a numeric histogram in a single low-cost call. It is ideal for VFX or rendering pipeline analytics where you want to understand asset group distribution and render time or node count spread without setting up a local analysis environment. Prefer it over general-purpose analytics tools when the dataset fits within 200 rows and cost efficiency ($0.01 per call for two reports) matters.

## Known failure modes

- Fewer than 1 or more than 200 rows supplied — request rejected
- Invalid date format (not YYYY-MM-DD) in any row — validation error
- Bins parameter outside 1–30 range — request rejected
- Missing required fields (row_id, asset_group, date, node_count, render_seconds) in any row — schema validation failure
- Null values in the selected numeric field may be excluded from histogram computation
- Payment of 0.01 USDC not confirmed — request not processed

## How this service works

Compositing graphs — Category frequencies + Equal-width histogram: Category frequencies + Equal-width histogram 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 analytical reports: (1) a category frequency table showing how often each asset_group value appears in the supplied rows, and (2) an equal-width histogram for the chosen numeric field (node_count or render_seconds) divided into the specified number of bins, with row counts per bin. Both reports are computed locally on the supplied data with no external lookups.
