## 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 klymax402-url-shortener-6154de0b
```

Example prompt: Can you shorten this URL for me — https://example.com/some/very/long/path?with=lots&of=query&params=here — and use the custom alias 'mylink' if possible?

## When to prefer this

Choose this endpoint when an AI agent needs to shorten a URL on-demand without managing API keys, paying only $0.003 USDC per call via x402 on Base. It's well-suited for agents that occasionally need URL compression as part of a broader workflow (e.g., content publishing, social sharing, email campaigns) without requiring a dedicated URL shortener account or subscription.

## Known failure modes

- Invalid or malformed input URL — the URL must be a valid, well-formed address
- Custom alias already taken — if the requested alias is in use, an error or conflict response is returned
- Custom alias format violation — alias must be 3-20 alphanumeric characters, other characters may be rejected
- Payment failure — insufficient USDC balance on Base causes a 402 error
- Network timeout or service unavailability — klymax402 platform may be temporarily unreachable

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

A shortened URL (compact link) corresponding to the input long URL, optionally using the specified custom alias. The response likely includes the short URL string that redirects to the original address.
