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 delx-pad-right-cb68c102 -d '<json body>'
```

Example prompt: Pad the text 'Status' to a width of 20 characters using a dot as the fill character so I can use it in a fixed-width column.

## When to prefer this

Choose this endpoint when you need a lightweight, stateless, pay-per-call string padding operation without shipping any string-formatting library or writing custom code — especially useful in agent pipelines that produce columnar logs or fixed-width text output and want a deterministic, local-only utility with no data retention.

## Known failure modes

- Width less than or equal to current string length returns the original string unmodified
- Non-integer width value causes a validation error
- Missing required fields (text or width) return a 400-level error
- Fill string longer than one character may cause unexpected behavior or an error

## How this service works

Right-pad a string to a target width. Call when you need fixed-width columns for agent logs. Returns padded text and width 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 JSON object containing the padded string (with fill characters appended on the right until the target width is reached) and the resulting output width as an integer.
