Input

Field	Description
`keyword`	Optional NVD `keywordSearch` (e.g. `openssl`).
`cveIds`	Optional exact CVE IDs. When set, fetches those IDs directly.
`cvssV3Severity`	Optional: `LOW`, `MEDIUM`, `HIGH`, `CRITICAL`.
`pubStartDate` / `pubEndDate`	Publication window (`YYYY-MM-DD`). Defaults to last 7 days (UTC). NVD allows at most 120 days.
`maxItems`	Cap on saved rows (1–2000, default 50).
`resultsPerPage`	Page size 1–100 (default 50).
`requestDelayMs`	Pause between pages (default 6500; unauthenticated ~5 req/30s).
`nvdApiKey`	Optional free key from nvd.nist.gov (secret).

Output

Each dataset item includes: cveId, published, lastModified, vulnStatus, description, cvssVersion, cvssScore, cvssSeverity, cvssVector, cwes, references, nvdUrl, sourceIdentifier.

Local run

cd nist-nvd-cves
python3 -m venv .venv && .venv/bin/pip install -r requirements.txt
apify run --purge -i '{"cvssV3Severity":"CRITICAL","maxItems":5,"requestDelayMs":1000}'

Rate limits

Without an API key, NIST limits unauthenticated clients to about 5 requests per 30 seconds. Use the default delay, keep maxItems modest for demos, or supply a free nvdApiKey.
