# API Contracts — Exact Row Deduplication + Base-100 Series

> API Contracts — Exact Row Deduplication + Base-100 Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Deduplicates rows in API contract records and computes a Base-100 index series for a chosen numeric field, returning two analytical reports for up to 200 rows.

## 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 api-contracts-exact-row-deduplication-base-100-series-56ca7c42 -d '<json body>'
```

Example prompt: Can you deduplicate these api contract rows and generate a Base-100 series for the fields_checked column, starting from row index 0? I have 4 rows with components group-a and group-b dated from 2026-10-01 to 2026-10-04.

## When to prefer this

Choose this endpoint when you need both exact duplicate row detection and Base-100 normalization of a numeric series in a single call on api contract data. It is ideal for software teams analyzing API contract compliance metrics (fields_checked, incompatible_fields) over time across components, where you want a cleaned dataset and a normalized trend index together without setting up a local analytics pipeline. It processes up to 200 rows per call at minimal cost ($0.01 USDC for both reports).

## Known failure modes

- Exceeds 200 row limit — request rejected or truncated
- Invalid date format not matching YYYY-MM-DD pattern — validation error
- Missing required fields (row_id, component, date, fields_checked, incompatible_fields) — schema error
- base_index out of range (0–199) — error or unexpected indexing
- Numeric field values outside allowed range (-1e12 to 1e12) — validation failure
- Empty rows array (minItems:1 not met) — schema rejection

## How this service works

API contracts — Exact row deduplication + Base-100 series: Exact row deduplication + Base-100 series for supplied api contracts records (fields_checked, incompatible_fields). 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: (1) a deduplicated version of the submitted rows with exact duplicate records removed, and (2) a Base-100 index series for the selected numeric field (fields_checked or incompatible_fields), anchored at the specified base_index row. Both reports are computed locally from the supplied data with no external lookups.
