# Commercial Proposal Comparisons — Numeric Interval Filter + Two-Measure Correlation

> Commercial Proposal Comparisons — Numeric Interval Filter + Two-Measure Correlation 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).

Filters commercial proposal rows by a numeric interval on a chosen field and computes correlation between quoted_amount and delivery_days across up to 200 rows, returning two analytical reports.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-two-measure-2619dc87 -d '<json body>'
```

Example prompt: I have 150 commercial proposal rows with quoted_amount and delivery_days — filter them to only those with quoted_amount between 5000 and 50000, then run a two-measure correlation between quoted_amount and delivery_days across all filtered results and give me both reports.

## When to prefer this

Choose this endpoint when you need to simultaneously filter a commercial proposal dataset by a numeric range on one measure and compute a statistical correlation between quoted_amount and delivery_days — all in a single $0.01 call covering up to 200 rows and two reports. Prefer it over general analytics tools when working specifically with vendor/supplier proposal data that has these two standard numeric fields, and when you need both a filtered view and a cross-measure relationship in one operation without any external API dependencies.

## Known failure modes

- Empty rows array or rows below minItems=1 returns a validation error
- Minimum value greater than maximum value may yield an empty filtered set with no correlation computable
- Non-conforming date strings (not YYYY-MM-DD) trigger schema validation failure
- Rows exceeding maxItems=200 are rejected
- Null values in quoted_amount or delivery_days may reduce effective sample size for correlation
- Invalid field enum value (not 'quoted_amount' or 'delivery_days') causes a schema error

## How this service works

Commercial proposal comparisons — Numeric interval filter + Two-measure correlation: Numeric interval filter + Two-measure correlation 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 independent analytical reports: (1) the subset of input rows whose chosen numeric field (quoted_amount or delivery_days) falls within the specified minimum-maximum interval, and (2) a correlation analysis between quoted_amount and delivery_days computed over the supplied rows, all processed locally without external data lookups.
