## 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 virustotal-url-comments-via-locus-x402-dc91b710 -d '<json body>'
```

Example prompt: Can you pull up the VirusTotal community comments for https://suspicious-site.example.com — grab the top 10 most recent ones so I can see what security researchers are saying about it?

## When to prefer this

Choose this endpoint when you need qualitative, human-authored community intelligence about a URL — specifically analyst annotations and researcher notes from the VirusTotal community — rather than raw scan verdicts from antivirus engines. This is ideal when you want to supplement automated scan results with contextual commentary, or when investigating a URL that may have been discussed or annotated by security professionals. Prefer this over full scan endpoints when you already have AV verdicts and want the human intelligence layer.

## Known failure modes

- URL not found in VirusTotal database — empty or null data returned
- Invalid URL format — request rejected or no results
- Payment failure — USDC transaction not settled, request not processed
- Rate limiting — too many requests in a short window
- Network timeout — the upstream VirusTotal API is unresponsive
- Limit parameter out of range — may default or return error

## How this service works

Threat intelligence platform — scan files by hash, URLs, domains, and IPs against 70+ antivirus engines and security tools.

## Output

Returns a data object containing community-submitted comments associated with the queried URL on VirusTotal, along with payment settlement details (amount charged in USDC) and a request tracking ID. The comments include annotations, notes, and observations posted by security researchers and the VirusTotal community about the URL's threat profile.
