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 industrial-platform-web-tools-url-code-encoder-decoder-dc4b653c -d '<json body>'
```

Example prompt: Take this string 'Hello World! 你好 & more?' and URL-encode it so I can safely include it as a query parameter — use encode mode.

## When to prefer this

Choose this endpoint when you need a quick, machine-payable URL encoding or decoding operation without standing up your own infrastructure. Ideal for AI agents operating in x402-enabled payment flows that need to encode/decode strings on the fly as part of a larger workflow (e.g., constructing URLs, processing API responses).

## Known failure modes

- Input text exceeds 250,000 character limit — request rejected
- Missing required 'text' field in body — validation error
- Invalid 'mode' value (must be 'encode' or 'decode') — enum validation failure
- Malformed JSON body — parse error
- Payment not received or insufficient USDC — x402 payment required error

## How this service works

Machine-payable x402 utilities for hashing, Base64, UUID generation, unit and timezone conversion, realtime crypto market data, webpage/document extraction, URL-to-Markdown, metadata, RAG ingestion and deterministic website change detection.

## Output

Returns a JSON object containing the transformed text — either the URL-encoded (percent-encoded) version of the input string, or the decoded plain-text version, depending on the chosen mode.
