# API Contracts — Duplicate Key Report + Daily Sum Series

> API Contracts — Duplicate Key Report + Daily Sum 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).

Analyzes up to 200 rows of API contract records to produce a duplicate key report and a daily sum time series for fields_checked or incompatible_fields.

## 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-duplicate-key-report-daily-sum-series-0a9688cb -d '<json body>'
```

Example prompt: Can you run a duplicate key report and daily sum series on my API contract records for the fields_checked metric? I have about 150 rows with dates, row IDs, and component names — let me know which rows are duplicates and what the day-by-day totals look like.

## When to prefer this

Choose this endpoint when you need two specific analytical outputs — duplicate key detection and daily sum aggregation — on a small-to-medium batch of API contract records (up to 200 rows) in a single low-cost call. Ideal when you want local, offline-style computation without external lookups, predictions, or live data dependencies. Best suited for data quality audits and time-series summaries on contract monitoring data.

## Known failure modes

- Fewer than 1 row provided — returns validation error
- More than 200 rows submitted — exceeds maxItems limit
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Missing required fields (row_id, component, date) — rejected input
- Numeric values out of allowed range (±1 trillion) — validation error
- Invalid field selector value — must be 'fields_checked' or 'incompatible_fields'

## How this service works

API contracts — Duplicate key report + Daily sum series: Duplicate key report + Daily sum 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 independent reports: (1) a duplicate key report identifying rows with repeated key combinations from the supplied API contract records, and (2) a daily sum time series aggregating the selected numeric field (fields_checked or incompatible_fields) by date — both computed locally on up to 200 input rows.
