## 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-url-decode-safe-510874a9 -d '<json body>'
```

Example prompt: Can you percent-decode this URL-encoded string for me: 'Hello%20World%21%20How%27s%20it%20going%3F' — I need the plain readable text back.

## When to prefer this

Choose this endpoint when you need to safely reverse percent-encoding on a captured URL component, query parameter, or path segment — especially when robustness to malformed input matters. Prefer this over the sibling URL Encode endpoint when the direction is decode-only. Use when you want a stateless, no-retention, local decode with no side effects and a guaranteed sub-cent cost via x402.

## Known failure modes

- Malformed percent sequences (e.g. truncated % escapes) may be passed through as-is or cause an error response
- Empty or null text input may return an error or empty result
- Input that is not actually percent-encoded will be returned unchanged
- Non-UTF-8 encoded sequences may not decode correctly

## How this service works

Percent-decode text. Call when you reverse query encoding from agent-held URLs. Returns decoded text 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

A JSON object containing the decoded plain text string, with all percent-encoded sequences (e.g. %20, %2F, %3A) converted back to their original characters. No network calls are made; the operation is local and stateless.
