# Commercial Proposal Comparisons — Duplicate Key Report + Equal-Width Histogram

> Commercial Proposal Comparisons — Duplicate Key Report + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Analyzes up to 200 commercial proposal comparison records to produce a duplicate key report and an equal-width histogram for quoted_amount or delivery_days 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 commercial-proposal-comparisons-duplicate-key-report-equal-width-f5fb214b -d '<json body>'
```

Example prompt: Can you run a duplicate key check and a 10-bin equal-width histogram on my commercial proposal data for the quoted_amount field? Here are the rows: row-1, Vendor A, 2026-01-15, $4500, 30 days; row-2, Vendor B, 2026-01-16, $3800, 45 days; row-3, Vendor A, 2026-01-15, $4500, 30 days.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) dual-report analysis of commercial proposal data — specifically duplicate key detection plus histogram bucketing — on a dataset of up to 200 rows, without requiring any external data enrichment, prediction, or professional assessment. Ideal for procurement teams running data quality checks and distribution analysis on vendor bids in a single call.

## Known failure modes

- More than 200 rows submitted — request will be rejected or truncated
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Missing required fields (row_id, company_group, date, quoted_amount, delivery_days) causes rejection
- bins value outside 1–30 range causes validation error
- All values null for selected field results in empty or degenerate histogram
- Payment not included or insufficient USDC causes 402 response

## How this service works

Commercial proposal comparisons — Duplicate key report + Equal-width histogram: Duplicate key report + Equal-width histogram 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 reports: (1) a duplicate key report listing any row_ids that appear more than once along with their associated records, and (2) an equal-width histogram showing the distribution of values (quoted_amount or delivery_days) across the specified number of bins, including bin boundaries and row counts per bin. Both reports are computed locally on the supplied data with no external lookups.
