+# API Reference: Vulnerability Prioritization with CVSS Scoring
+
+## CVSS v3.1 Base Metrics
+
+| Metric | Values | Description |
+|--------|--------|-------------|
+| AV (Attack Vector) | N, A, L, P | Network, Adjacent, Local, Physical |
+| AC (Attack Complexity) | L, H | Low, High |
+| PR (Privileges Required) | N, L, H | None, Low, High |
+| UI (User Interaction) | N, R | None, Required |
+| S (Scope) | U, C | Unchanged, Changed |
+| C (Confidentiality) | N, L, H | None, Low, High |
+| I (Integrity) | N, L, H | None, Low, High |
+| A (Availability) | N, L, H | None, Low, High |
+
+## Severity Ratings
+
+| Score Range | Rating |
+|-------------|--------|
+| 0.0 | None |
+| 0.1-3.9 | Low |
+| 4.0-6.9 | Medium |
+| 7.0-8.9 | High |
+| 9.0-10.0 | Critical |
+
+## EPSS API (FIRST.org)
+
+| Endpoint | Description |
+|----------|-------------|
+| `GET https://api.first.org/data/v1/epss?cve=CVE-XXXX` | Get EPSS score |
+| Response: `data[].epss` | Exploit probability (0-1) |
+| Response: `data[].percentile` | Percentile ranking |
+
+## CISA KEV Catalog
+
+| Field | Description |
+|-------|-------------|
+| URL | `https://www.cisa.gov/sites/default/files/feeds/known_exploited_vulnerabilities.json` |
+| `vulnerabilities[].cveID` | CVE identifier |
+| `vulnerabilities[].dateAdded` | Date added to KEV |
+| `vulnerabilities[].dueDate` | Remediation deadline |
+
+## Priority Scoring Formula
+
+```
+priority = cvss_score * 10
+  + 30 if in CISA KEV
+  + 20 if EPSS > 0.5
+  + 10 if EPSS > 0.1
+```
+
+## Python Libraries
+
+| Library | Version | Purpose |
+|---------|---------|---------|
+| `requests` | >=2.28 | Fetch EPSS and KEV data |
+| `math` | stdlib | CVSS score rounding |
+| `json` | stdlib | Report generation |
