# Bundle Contribution Benchmark Correlation

> Bundle Contribution Benchmark Correlation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Calculates the Pearson or rank correlation between bundle contribution margins and a set of benchmark values for retail bundle pricing analysis.

## 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 bundle-contribution-benchmark-correlation-e863d05f -d '<json body>'
```

Example prompt: Can you calculate the benchmark correlation for these four retail bundles — bundle prices 100, 110, 100, 110; item costs 50, 55, 50, 55; packing costs 5, 5.5, 5, 5.5; fulfilment costs 10, 11, 10, 11 — against benchmarks of 10, 20, 30, and 40?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01 USDC) local correlation calculation between retail bundle contribution margins and a benchmark series for scenario analysis or pricing strategy work. Prefer it over general-purpose statistical tools when working specifically with retail bundle cost structures (item costs, packing, fulfilment). Not appropriate for live inventory lookups, order execution, or real-time market data.

## Known failure modes

- Fewer than 2 rows provided — minItems constraint violated
- Fewer than 2 benchmarks provided — minItems constraint violated
- More than 200 rows or benchmarks provided — maxItems constraint exceeded
- Negative or non-numeric values passed for costs or prices
- Mismatched array lengths between rows and benchmarks may yield unexpected correlation results
- Missing required fields (bundle_price, item_costs, packing_cost, fulfilment_cost) in any row

## How this service works

Bundle contribution - Benchmark correlation: Benchmark correlation for Bundle contribution. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded benchmark correlation deliverable.

## Output

Returns a bounded benchmark correlation deliverable — a correlation coefficient or score measuring how closely the computed bundle contribution margins (bundle_price minus item_costs, packing_cost, and fulfilment_cost) align with the supplied benchmark series, along with scenario analysis output. No live inventory, account, or order data is involved.
