# OSF Security Record Lookup (CVE/KEV/EPSS/GHSA/CWE/ATT&CK)

> OSF Security Record Lookup (CVE/KEV/EPSS/GHSA/CWE/ATT&CK) is a paid API for AI agents from api.osf-master-server.com, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-15).

Fetches a single verified security/vulnerability data record by ID, covering NVD CVE, CISA KEV, EPSS exploitation scores, GitHub Security Advisories, CWE weakness classes, or MITRE ATT&CK techniques, with full JSON and a provenance URL.

## Facts

- Endpoint: GET https://api.osf-master-server.com/x402/buy/security/:record_id
- Price: $0.04/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/osf-security-record-lookup-cve-kev-epss-ghsa-cwe-att-ck-178ce001
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_e4VGO3KLwD-9CuTwBxMjy

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 osf-security-record-lookup-cve-kev-epss-ghsa-cwe-att-ck-178ce001
```

Example prompt: Pull the full security record for OSF record ID 4821 in JSON format — I need the CVE details, CVSS score, CISA KEV status, and EPSS exploitation probability, along with the provenance link to the primary source.

## When to prefer this

Choose this endpoint when you need a single, authoritative, provenance-stamped security record from any of the major vulnerability and threat intelligence databases (NVD, CISA KEV, EPSS, GitHub SA, CWE, MITRE ATT&CK) in one unified call. Prefer it over scraping individual databases directly when auditability, provenance, and structured JSON output matter. At $0.04 per call it is the lowest-cost tier in the OSF security data lineup, suitable for high-volume per-record lookups.

## Known failure modes

- Record ID not found — returns 404 or error status
- Payment not completed (x402 flow) — returns 402 Payment Required
- Invalid or missing format query parameter — returns 400 bad request
- Record type not available for the given ID — returns empty data object
- Network timeout on upstream data source — returns 5xx error

## How this service works

Security and vulnerability data, one record per call: NVD CVE with CVSS severity, CISA KEV actively-exploited status, EPSS daily exploitation scores, GitHub Security Advisories, CWE weakness classes, MITRE ATTACK techniques. Full JSON plus a provenance URL to the primary source.

## Output

A JSON object containing the full security record for the requested ID, which may include NVD CVE details and CVSS severity scores, CISA KEV active-exploitation status, EPSS daily exploitation probability scores, GitHub Security Advisory data, CWE weakness classifications, or MITRE ATT&CK technique information — plus a provenance_url pointing back to the authoritative primary source.
