## 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-file-report-via-locus-x402-c0580045 -d '<json body>'
```

Example prompt: Can you check VirusTotal to see if this file hash is malicious — SHA-256: 275a021bbfb6489e54d471899f7db9d1663fc695ec2fe2a2c4538aabf651fd0f?

## When to prefer this

Use this endpoint when you need to check whether a specific file is malicious using its hash and want results from 70+ antivirus engines simultaneously without uploading the actual file. Ideal for security pipelines, incident response triage, SIEM enrichment, or any workflow where you already have a file hash and need a quick threat verdict. Prefer over direct VirusTotal API access when you want pay-per-call micropayment billing via x402 with no API key management.

## Known failure modes

- Hash not found in VirusTotal database — file may never have been submitted for analysis
- Invalid hash format (not a valid MD5, SHA-1, or SHA-256) returns an error
- Payment failure or insufficient USDC balance prevents the request from completing
- Rate limiting if too many requests are made in quick succession
- Network timeout if VirusTotal backend is slow to respond
