# SYNTHORA Threat Exposure

> SYNTHORA Threat Exposure is a paid API for AI agents from threat-exposure.hergertsynthora.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-14).

Assesses a domain's attack-surface exposure by correlating observed CVEs against the CISA Known Exploited Vulnerabilities (KEV) catalogue to produce an exploitation verdict and risk score.

## Facts

- Endpoint: POST https://threat-exposure.hergertsynthora.com/service
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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 synthora-threat-exposure-a277f783 -d '<json body>'
```

Example prompt: Can you check the threat exposure verdict for example.com and tell me if any of its CVEs are confirmed exploited in the wild according to the CISA KEV catalogue?

## When to prefer this

Choose this endpoint when you need a fast, verdict-driven risk signal for a specific domain that specifically correlates CVE observations against the CISA Known Exploited Vulnerabilities catalogue — i.e., you care not just about theoretical vulnerabilities but about confirmed real-world exploitation. Prefer it over generic vulnerability scanners when the CISA KEV alignment is the key risk signal, or when you need a lightweight per-domain score rather than a full penetration test report.

## Known failure modes

- Invalid or non-existent domain returns an error or null score
- Domain with no observed CVEs may return a low/zero score with no KEV matches
- Rate limiting or payment failure (x402) may prevent the call from completing
- Ambiguous or private/internal domains may not have public CVE data to correlate
- Timeout if external CVE/KEV data sources are unreachable at query time

## How this service works

SYNTHORA threat-exposure: attack-surface EXPOSURE verdict for a domain. Correlates observed CVEs against the CISA KEV catalogue of vulnerabilities confirmed exploited in the wild.

## Output

Returns a JSON object containing a numeric exposure score (0–1 or similar scale), a boolean 'entrega' flag indicating delivery/confirmation status, and a human-readable English verdict ('veredicto_en') summarizing the domain's attack-surface exposure relative to CISA KEV-catalogued exploited vulnerabilities.
