## 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 delx-pct-of-d5dd49d4 -d '<json body>'
```

Example prompt: What percentage is 47 out of 200? Use the Delx percent calculator to get me that number.

## When to prefer this

Use this endpoint when an agent needs a quick, stateless percentage calculation without any external dependencies or data retention. Ideal for populating dashboard metrics, progress bars, or share indicators in real time where the inputs are already known integers and no local computation environment is available.

## Known failure modes

- whole equals zero — division by zero error
- non-integer values passed for part or whole — schema validation failure
- missing required fields (part or whole) — request rejected
- negative values for part or whole — may return unexpected results depending on server validation

## How this service works

Compute part/whole as percent. Call when you express progress or share for agent dashboards. Returns percent value for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns a single numeric percentage value representing (part / whole) × 100, indicating what fraction the part is of the whole.
