## 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 speer-cyber-defense-claim-verification-fb8817e1 -d '<json body>'
```

Example prompt: Can you verify this security claim — 'Log4Shell affects all Java applications running Log4j 2.x' — against these two sources: https://nvd.nist.gov/vuln/detail/CVE-2021-44228 and https://logging.apache.org/log4j/2.x/security.html?

## When to prefer this

Choose this endpoint when you need to fact-check or validate a specific cybersecurity claim against one or more cited sources, especially when the claim relates to CVEs, threat actors, vulnerabilities, or security advisories. It is pay-per-call ($0.002 USDC) so cost is negligible, and failed analyses are not charged, making it safe for exploratory verification tasks. Prefer it over general web search when you need a structured, summarized verdict on claim accuracy grounded in specific reference URLs.

## Known failure modes

- HTTP 503 returned when security analysis fails (not billed)
- Invalid or unreachable source URLs may degrade verification quality
- Vague or ambiguous claim text may produce inconclusive summaries
- Payment failure via x402 protocol blocks access
- Empty or missing 'text' field causes request rejection
