# Compositing Graphs — Duplicate Key Report + Equal-Width Histogram

> Compositing Graphs — Duplicate Key Report + 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 analytical reports on compositing graph records: a duplicate key report and an equal-width histogram, for up to 200 rows of node_count/render_seconds data.

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-duplicate-key-report-equal-width-histogram-cbdf0fbc -d '<json body>'
```

Example prompt: Can you check my compositing graph records for duplicate keys and also generate an equal-width histogram with 10 bins for render_seconds? Here are my rows: row-1 (group-a, 2026-10-01, node_count=10, render_seconds=1.5), row-2 (group-b, 2026-10-02, node_count=20, render_seconds=3.2), row-3 (group-a, 2026-10-01, node_count=10, render_seconds=1.5).

## When to prefer this

Choose this endpoint when you need simultaneous duplicate key detection and distribution analysis on compositing graph records (node_count or render_seconds) in a single paid call. It is best suited for small-to-medium datasets up to 200 rows where you want both data quality (duplicate check) and statistical insight (histogram) without external dependencies or live data lookups.

## Known failure modes

- Rows array is empty or missing — returns validation error
- More than 200 rows supplied — request rejected at schema level
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Bin count outside 1–30 range — rejected by schema
- Field value not one of node_count or render_seconds — enum validation error
- Null values in numeric fields may affect histogram bin computation
- row_id missing or exceeding 80 characters — schema validation error

## How this service works

Compositing graphs — Duplicate key report + Equal-width histogram: Duplicate key report + 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 duplicate key report identifying rows with repeated identifiers in the supplied compositing graph dataset, and (2) an equal-width histogram showing the frequency distribution of values in the chosen field (node_count or render_seconds) across the specified number of bins. Both reports are computed locally from the supplied data with no external lookups.
