## 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 x402-url-safety-check-d1463677 -d '<json body>'
```

Example prompt: Before my agent visits this link, can you run a pre-flight URL safety check on https://suspicious-promo.example.com and tell me if it's safe, phishing, or malicious?

## When to prefer this

Choose this endpoint when an AI agent needs a lightweight, pay-per-call URL safety gate before navigating to, scraping, or sharing a link — especially useful in agentic pipelines where no API key or signup is desired and a one-off micropayment via x402 is acceptable. Prefer this over full web-crawl safety products when you only need a quick binary or categorical safety verdict on a single URL.

## Known failure modes

- Missing or malformed URL input returns an error status
- Payment of $0.05 USDC not completed results in HTTP 402 and no classification
- Unknown or unresolvable domains may return inconclusive results
- Endpoint hosted on bare IP with sslip.io domain may experience availability issues

## How this service works

Pay-per-call agent utilities: pre-flight compliance classification, pre-flight URL safety, composed company/market research, live web search, page scraping, and keyword planning. Pay $0.001 USDC (research/classify/url_safety/search/scrape) or $0.002 USDC (keyword_plan) per call via x402 -- no API keys, no signup.

## Output

A JSON response indicating the safety status of the submitted URL — whether it is safe, suspicious, or malicious — along with a success/failure status field.
