# Synthr Cyber Security Intelligence

> Synthr Cyber Security Intelligence is a paid API for AI agents from synthr.online, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Provides agent-native cybersecurity intelligence including vulnerability data (OSV, EPSS, KEV), dependency audits, stack security briefs, and web reconnaissance for packages and ecosystems.

## Facts

- Endpoint: POST https://synthr.online/v1/cyber/research
- Price: $0.005/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 synthr-cyber-security-intelligence-d1c7a912 -d '<json body>'
```

Example prompt: Can you audit the npm package 'axios' version 1.6.0 for known vulnerabilities — pull real OSV, EPSS, and KEV data and tell me if it's actively exploited or high priority to patch?

## When to prefer this

Use this endpoint when you need real, authoritative vulnerability data from OSV, EPSS, and CISA KEV for a specific package or ecosystem — especially when building autonomous security pipelines, CI/CD dependency audits, or when you need exploit probability scoring and known-exploited classification rather than a generic security scan.

## Known failure modes

- Unknown or misspelled package name returns empty or irrelevant results
- Unsupported ecosystem may yield no vulnerability data
- Missing required 'query' field returns a validation error
- LLM synthesis (useLlm=true) costs extra and may time out under load
- Very new packages may have no OSV data yet

## How this service works

Agent-native cybersecurity intelligence. Real OSV + EPSS + KEV data. Stack briefs, dep audits, advice, web reconnaissance. Prioritized for autonomous builders and harnesses.

## Output

Returns a timestamped analysis object with a queryId, the list of sources consulted (OSV, EPSS, KEV), a written analysis of the security posture, and an array of prioritized security recommendations.
