# Unit Fill Rate – Named Scenario Comparison

> Unit Fill Rate – Named Scenario Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).

Computes and compares unit fill rate metrics across multiple named scenarios using supplied retail figures, with a baseline and up to 20 labeled overrides.

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 unit-fill-rate-named-scenario-comparison-5d439999 -d '<json body>'
```

Example prompt: I have a baseline of 100 ordered units and 95 fulfilled. Compare that to two scenarios: 'Holiday Rush' where 200 are ordered but only 160 fulfilled, and 'Supplier Delay' where 100 are ordered and only 72 fulfilled — what's the fill rate for each?

## When to prefer this

Choose this endpoint when you need to compare unit fill rate performance across multiple explicitly named retail scenarios using your own supplied figures, without requiring live inventory access or platform connectivity. It is ideal for offline planning, budget modeling, and supply chain stress-testing where you control the input data and want labeled, bounded scenario outputs at low cost.

## Known failure modes

- ordered_units of 0 or missing causes a division-by-zero or validation error
- fulfilled_units exceeding ordered_units may return a fill rate above 100% with no warning
- more than 20 scenarios provided causes request rejection
- missing required label or overrides fields in a scenario item causes validation failure
- non-numeric values in unit fields cause schema validation errors

## How this service works

Unit fill rate - Named scenario comparison: Named scenario comparison for Unit fill rate. Supplied retail figures only. Local calculation and scenario analysis; no live inventory, account access, platform fee lookup or order execution. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded named scenario comparison deliverable.

## Output

Returns a structured comparison of unit fill rate (fulfilled_units / ordered_units) for the baseline and each named scenario, labeled according to the supplied scenario names. Each result includes the calculated fill rate percentage for that scenario, enabling side-by-side analysis of fulfillment performance across conditions.
