## 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 commercial-proposal-comparisons-adjacent-row-changes-base-100-series-cd344c53 -d '<json body>'
```

Example prompt: I have a list of commercial proposals with quoted amounts and delivery days for two vendor groups — can you run both an adjacent row change report and a base-100 index series on the quoted_amount field, starting from row index 0? Here are the rows: [{"row_id":"r1","company_group":"vendor-a","date":"2026-01-01","quoted_amount":5000,"delivery_days":10},{"row_id":"r2","company_group":"vendor-b","date":"2026-01-02","quoted_amount":5500,"delivery_days":12},{"row_id":"r3","company_group":"vendor-a","date":"2026-01-03","quoted_amount":4800,"delivery_days":9}].

## When to prefer this

Choose this endpoint when you have a structured list of commercial proposal records (with quoted amounts and/or delivery days) and need both a sequential row-change report and a base-100 indexed series in a single API call for under $0.01. Ideal for procurement analytics, vendor bid comparison, or any scenario requiring normalized trend analysis across proposal rows without external data dependencies.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, company_group) cause validation errors
- base_index out of range (>= number of rows) causes indexing failure
- Null values in quoted_amount or delivery_days may produce null deltas in row change report
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Field enum value not 'quoted_amount' or 'delivery_days' causes rejection

## How this service works

Commercial proposal comparisons — Adjacent row changes + Base-100 series: Adjacent row changes + Base-100 series for supplied commercial proposal comparisons records (quoted_amount, delivery_days). 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 analytical reports for the supplied rows: (1) an adjacent row change report showing the numeric difference between each consecutive row for the selected field, and (2) a base-100 series report normalizing all row values relative to the chosen base index row. Both reports operate locally on the supplied data with no external lookups.
