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 api-links-safety-check-onchain-trading-intelligence-suite-b6135efd -d '<json body>'
```

Example prompt: Can you check whether these URLs are safe before I forward them to the trading bot: https://pump.fun/token/xyz and https://raydium.io/swap/?inputCurrency=sol — I want to make sure none of them are phishing or scam links.

## When to prefer this

Use this endpoint when an AI agent needs to pre-screen a batch of up to 50 URLs for safety or validity before acting on them, particularly in onchain/DeFi contexts where scam and phishing links are common. Prefer this over generic web-scraping tools when you need a lightweight, pay-per-call link check without API keys or subscriptions.

## Known failure modes

- Empty or malformed URLs in the array return validation errors
- Arrays exceeding 50 URLs are rejected
- Network timeouts if target URLs are slow to respond
- False negatives on newly registered phishing domains not yet flagged
- Payment failure if USDC balance is insufficient for the $0.003 per-call fee

## How this service works

Batch link-liveness: check up to 50 URLs return 200 (dead-link detection). Send { urls: [..] }.

## Output

Returns a safety or validity status for each submitted URL, indicating whether each link is safe, live, suspicious, or flagged — enabling downstream agents to act only on verified links.
