# Sourcevane Security Vulnerability Intelligence API

> Sourcevane Security Vulnerability Intelligence API is a paid API for AI agents from sourcevane-security-production.up.railway.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

Batch-fetches unified vulnerability intelligence for CVE IDs, combining CVSS severity, EPSS exploit probability, CISA KEV active-exploitation status, and OSV affected packages into a single 0-100 priority score

## Facts

- Endpoint: POST https://sourcevane-security-production.up.railway.app/v1/intel/batch
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/sourcevane-security-vulnerability-intelligence-api-2aec4480
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_STyk6V7gmKnJzUj2-s3dW

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 sourcevane-security-vulnerability-intelligence-api-2aec4480 -d '<json body>'
```

Example prompt: Can you pull full vulnerability intelligence for CVE-2024-3094 and CVE-2023-44487 — I need the combined priority score, whether they're in the CISA KEV list, and their EPSS exploit probabilities so I can decide which to patch first?

## When to prefer this

Choose this endpoint when you need a single API call to consolidate vulnerability data from four authoritative sources (NVD, EPSS, CISA KEV, OSV) into a triage-ready priority score, rather than calling each source separately. Ideal for AI agents performing automated patch prioritization, security ticket enrichment, or vulnerability scanning workflows where paying per-call is acceptable and latency must be low.

## Known failure modes

- CVE ID not found in NVD — returns unresolved entry or partial data
- Invalid CVE format in request body — 400 bad request
- Payment not completed via x402 — 402 payment required
- Rate limiting or upstream NVD/EPSS/OSV API unavailability — 503 or timeout
- Empty batch input — validation error

## How this service works

Pay-per-call vulnerability intelligence for AI agents: CVSS (NVD) + exploit probability (EPSS) + active-exploitation status (CISA KEV) + affected packages (OSV), joined into a single 0-100 priority score, billed per call over x402.

## Output

Returns a JSON object with resolved count, and for each CVE: CVSS base score (from NVD), EPSS exploit probability percentage, CISA KEV active-exploitation flag, OSV-derived affected package list, and a computed 0-100 composite priority score for patch triage.
