# Observed Unit Sales Velocity – One-Input Sensitivity Table

> Observed Unit Sales Velocity – One-Input Sensitivity Table is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Computes a one-input sensitivity table for observed unit sales velocity given varying values of sold_units or observed_days against a retail baseline.

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 observed-unit-sales-velocity-one-input-sensitivity-table-e6703206 -d '<json body>'
```

Example prompt: Run a one-input sensitivity table for my observed unit sales velocity — baseline is 84 units sold over 7 days, and vary the sold_units field across 75.6, 84, and 92.4 to show how velocity changes.

## When to prefer this

Choose this endpoint when you need a fast, affordable one-input sensitivity table specifically for retail unit sales velocity — particularly when you have a fixed baseline and want to see how a single variable (units sold or observation window length) affects the computed velocity across a range of scenarios. It is not suitable for two-input sensitivity, live POS data, order execution, or forecasting beyond the supplied figures.

## Known failure modes

- Missing required baseline fields (sold_units or observed_days) returns a validation error
- observed_days of 0 or negative triggers exclusiveMinimum validation failure
- Values array exceeding 50 items returns a schema validation error
- Non-numeric entries in the values array cause a type error
- Payment of 0.01 USDC not provided or rejected blocks execution

## How this service works

Observed unit sales velocity - One-input sensitivity table: One-input sensitivity table for Observed unit sales velocity. Supplied retail figures only, up to 200 records. No platform access, live rates or order execution. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded one-input sensitivity table report.

## Output

Returns a structured sensitivity table with one row per supplied value, showing the computed unit sales velocity (units per day) for each scenario alongside the fixed baseline inputs. Output is bounded to the supplied retail figures with up to 200 records and up to 50 scenario values per call.
