Also recent KEV additions and a pre-KEV EPSS watchlist. REST + MCP server.

Send up to 20 CVE IDs and get a patch-priority verdict for each, with the evidence behind it: CISA KEV status and due date, ransomware use, FIRST EPSS, CVSS and CISA's SSVC exploitation call. For security teams, MSPs, scanners and AI agents. Free tier, no key; plans from $5 (one-time pack) or $19/month.

## API (free tier without a key; paid API keys for more)
- [/api/priority](https://kevscope-api.cybermaxtools.com/api/priority?cve=CVE-2024-3400,CVE-2024-6387,CVE-2019-0001): Patch-priority verdict for up to 20 CVEs, with evidence
- [/api/kev/recent](https://kevscope-api.cybermaxtools.com/api/kev/recent?days=14): CVEs added to CISA KEV in the last N days, with EPSS
- [/api/watchlist](https://kevscope-api.cybermaxtools.com/api/watchlist?limit=10): Early warning: highest-EPSS CVEs that are not in CISA KEV yet
- GET for simple calls, POST a JSON body for lists. Same field names as the bulk version's dataset records.
- OpenAPI 3.1: https://kevscope-api.cybermaxtools.com/openapi.json

## MCP (remote, streamable HTTP, no auth)
- Endpoint: https://kevscope-api.cybermaxtools.com/mcp
- `cve_priority`: Patch-priority verdict for 1-20 CVE IDs with evidence: CISA KEV status (date added, due date, ransomware use), FIRST EPSS probability, CVSS (CNA or CISA-ADP), CISA SSVC exploitation/automatable/impact, vendor, product and links. Sorted most urgent first.
- `kev_recent`: CVEs added to the CISA Known Exploited Vulnerabilities catalog in the last N days, newest first, with due date, ransomware use and EPSS. Optional vendor/product text filter.
- `epss_watchlist`: The highest-EPSS CVEs (most likely to be exploited in 30 days) that are not in CISA KEV yet. Defaults to this year's CVE IDs.

## Limits
- Up to 20 CVEs per call; 10 calls a minute per IP on the free tier.
- Free tier: 200 calls a day per IP, no key. Paid keys from $5 (one-time pack) or $19/month (see Get an API key).
- Sources are asked live and cached up to 1 hour: CVE Program records (incl. CISA-ADP), FIRST EPSS (updated daily) and the CISA KEV catalog.
- The verdict is a transparent rule set on public data, not a guarantee; your own exposure and compensating controls still decide.

- https://kevscope-api.cybermaxtools.com/x402/api/priority: same as /api/priority, always pay-per-call (an unpaid call returns HTTP 402 with the payment requirements).

- https://kevscope-api.cybermaxtools.com/x402/api/watchlist: same as /api/watchlist, always pay-per-call (an unpaid call returns HTTP 402 with the payment requirements).
- Plain endpoints keep the free tier and API keys; with no key, they also answer 402 (instead of 429) once the free daily quota is used.
- Send the signed payment as X-PAYMENT (v1) or PAYMENT-SIGNATURE (v2); the receipt comes back in X-PAYMENT-RESPONSE / PAYMENT-RESPONSE. Failed calls are not charged.
