## 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 marketplace-proceeds-benchmark-correlation-calculator-0fad54a3 -d '<json body>'
```

Example prompt: I have 4 marketplace sales rows — gross sales of $100 and $110 alternating, fee percentages of 10% and 11%, fixed fees of $1 and $1.10, and refunds of $5 and $5.50 — can you calculate the benchmark correlation of my net proceeds against the benchmark series [10, 20, 30, 40]?

## When to prefer this

Choose this endpoint when you need a local, offline-style statistical correlation between computed net marketplace proceeds (after fees and refunds) and a user-supplied benchmark series, without needing live platform data, inventory lookups, or account access. Ideal for scenario planning, fee structure comparisons, and understanding how closely projected or historical proceeds track a target benchmark.

## Known failure modes

- Fewer than 2 rows provided — minimum minItems:2 required for correlation
- Benchmark array fewer than 2 items — correlation requires at least 2 points
- Row values exceed maximum thresholds (1e12 for monetary fields, 100 for fee_percent)
- Mismatched row count vs benchmark length may affect correlation meaningfulness
- Missing required fields (gross_sale, fee_percent, fixed_fee, refunds) in any row causes validation error
- Non-numeric values in numeric fields cause schema validation failure

## How this service works

Marketplace proceeds from supplied fees - Benchmark correlation: Benchmark correlation for Marketplace proceeds from supplied fees. 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 representing how closely the computed net marketplace proceeds (gross sale minus percentage fee, fixed fee, and refunds) correlate with the supplied benchmark series, along with any scenario analysis output. No live inventory, platform, or account data is included — calculation is local and deterministic.
