Query NVD API v2.0 in parallel with OSV for broader vulnerability coverage. Results are deduplicated by CVE ID, with NVD providing authoritative CVSS v3.1 scores and CWE classifications. Both sources now cache raw responses per-package (not per-version), so checking multiple versions of the same package reuses API calls. OSV version filtering uses client-side range matching against the affected events data.
