# Commercial Proposal Comparisons — Numeric Interval Filter + Equal-Width Histogram

> Commercial Proposal Comparisons — Numeric Interval Filter + 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).

Applies a numeric interval filter and generates an equal-width histogram for up to 200 commercial proposal comparison records (quoted_amount, delivery_days) in a single call, returning 2 analytical reports.

## 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-numeric-interval-filter-equal-width-a962286b -d '<json body>'
```

Example prompt: I have 150 vendor proposal records with quoted_amount and delivery_days fields — can you run a numeric interval filter keeping amounts between 500 and 5000, then build a 10-bin equal-width histogram on quoted_amount so I can see how bids are distributed?

## When to prefer this

Choose this endpoint when you have up to 200 commercial proposal records and need both a numeric range filter and a frequency histogram on quoted_amount or delivery_days in a single cheap call ($0.01 USDC). Ideal for procurement analytics, RFP bid analysis, or supplier comparison workflows where you want a quick distributional view without setting up a local analytics stack. Not suitable for real-time lookups, predictive modeling, or datasets exceeding 200 rows.

## Known failure modes

- Rows array empty or missing — validation error returned
- More than 200 rows submitted — request rejected
- Bins value outside 1–30 range — validation error
- quoted_amount or delivery_days values outside ±1,000,000,000,000 — rejected
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Minimum greater than maximum — may produce empty filter result
- Null values in the target field — excluded from histogram computation silently

## How this service works

Commercial proposal comparisons — Numeric interval filter + Equal-width histogram: Numeric interval filter + 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 2 analytical reports: (1) a numeric interval filter report showing which of the supplied rows fall within the specified [minimum, maximum] range for the chosen field, and (2) an equal-width histogram report dividing that field's values into the requested number of bins with counts per bin — all computed locally on the submitted data, up to 200 rows.
