## 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-charges-numeric-row-ordering-base-100-series-02c2f87f -d '<json body>'
```

Example prompt: I have 4 marketplace charge rows for two store groups from October 2026 — row-1 through row-4 with gross amounts 10, 20, 15, 30 and fees 1, 2, 3, 4. Can you give me numeric row ordering and a base-100 index series on the gross_amount field, starting from row index 0?

## When to prefer this

Choose this endpoint when you have raw marketplace charge records and need both a ranked/ordered view of rows and a normalized base-100 progression series for either gross_amount or fee_amount — all in a single cheap call. Ideal for e-commerce or marketplace operators who want to compare charge growth relative to a baseline period without spinning up their own analytics infrastructure.

## Known failure modes

- Empty rows array or missing required fields (row_id, date, gross_amount, fee_amount) causes validation error
- More than 200 rows submitted exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) fails pattern validation
- base_index out of range (>= number of rows) causes indexing error
- null values in the selected numeric field may affect index computation
- Payment not provided or insufficient funds returns 402 error

## How this service works

Marketplace charges — Numeric row ordering + Base-100 series: Numeric row ordering + Base-100 series for supplied marketplace charges records (gross_amount, fee_amount). 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 numeric row ordering of the supplied charge records, and (2) a base-100 index series for the selected field (gross_amount or fee_amount) starting from the specified base_index row. Both reports are computed locally from the supplied data with no external lookups.
