# OSF Cybersecurity Intelligence Search

> OSF Cybersecurity Intelligence Search is a paid API for AI agents from api.osf-master-server.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Search across CVE vulnerabilities, EPSS scores, CISA Known Exploited Vulnerabilities, GitHub advisories, CWE weaknesses, and MITRE ATT&CK techniques by keyword, vendor, or product

## Facts

- Endpoint: GET https://api.osf-master-server.com/x402/cyber/threats/:query
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/osf-cybersecurity-intelligence-search-c660a90a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_0zkQQY-8IAGRa_RZgedKd

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-cybersecurity-intelligence-search-c660a90a
```

Example prompt: Search for known CVE vulnerabilities, CISA exploited entries, and MITRE ATT&CK techniques related to 'Microsoft Exchange' — I need severity scores and source links for each match.

## When to prefer this

Use this endpoint when you need a broad, multi-source cybersecurity intelligence search across CVE, EPSS, CISA KEV, GitHub advisories, CWE, and MITRE ATT&CK in a single call. Prefer it over single-source CVE lookups when you want aggregated threat context for a vendor, product, or attack technique. For a known CVE ID with targeted exploit-status checking, consider the sibling CVE-specific endpoint instead.

## Known failure modes

- No results found for obscure or misspelled query — returns empty result set
- Query too broad (e.g. 'software') may return too many loosely related results
- Invalid or malformed CVE ID format may return no results
- Network timeout or upstream data source unavailability
- Payment failure (x402) if USDC balance is insufficient

## How this service works

Search cybersecurity intelligence by keyword, vendor, or product: the full NVD CVE corpus since 1988, CVE Program records, EU EUVD vulnerabilities, CISA KEV, 3,900+ CISA ICS advisories, EPSS scores, GitHub advisories, the full CWE catalog, and MITRE ATT&CK. Returns id, title, severity or score, and a provenance URL per match. For threat intel, vulnerability management, DevSecOps.

## Output

Returns a list of matches across CVE (NVD), EPSS exploit-probability scores, CISA Known Exploited Vulnerabilities, GitHub advisories, CWE weaknesses, and MITRE ATT&CK techniques. Each match includes an ID, title, severity or score, and a provenance URL pointing to the original source.
