## 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 nlp-malware-auditor-hash-based-malware-detection-3600bbb7 -d '<json body>'
```

Example prompt: Can you check if the hash d41d8cd98f00b204e9800998ecf8427e is malware — I want to know if this file is safe before I open it.

## When to prefer this

Use this endpoint when you need a fast, low-cost (sub-$0.07) boolean malware verdict for a single hash in an automated pipeline, CI/CD workflow, or SOC triage context where a simple true/false is sufficient and you do not need full threat-intelligence reports or behavioral analysis.

## Known failure modes

- Missing or empty hash field returns a validation error
- Malformed or non-standard hash format may return false negatives or an error
- Hash not found in database returns false (unknown, not necessarily clean)
- Payment failure via x402 returns HTTP 402 before execution
- Network timeout or node unavailability returns a 5xx error

## How this service works

## Output

Returns a JSON object with a single boolean field indicating whether the submitted hash is identified as malware (true = malicious, false = clean/unknown).
