## 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 signaldesk-ai-url-decode-2e33dbb6 -d '<json body>'
```

Example prompt: Can you decode this URL-encoded string for me: 'hello%20world%3F' — I need to see what it actually says in plain text.

## When to prefer this

Use this endpoint when you need a quick, paid, on-demand URL decoding operation via the x402 micropayment protocol — especially in agent workflows already integrated with the SignalDesk AI platform or using Cloudflare Workers-hosted tooling. At $0.001 USDC per call it is appropriate for occasional, low-volume decoding tasks rather than high-throughput batch processing.

## Known failure modes

- Malformed percent-encoding (e.g. incomplete sequences like '%2') may result in an error or partial decode
- Input exceeding 4096 characters will be rejected
- Invalid JSON body returns an error response
- Empty or missing 'text' field may return an error or empty decoded result

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object with a 'decoded' field containing the plain-text, human-readable version of the input URL-encoded string, with all percent-encoded sequences (e.g. %20, %3F) replaced by their literal characters.
