for https://github.com/dwelch2344/cve-ref-archival/blob/24ca51169ff07766fc5d35a2ab3bc8b2a47c195c/src/engine/cve/api.ts#L20-L21

const url = `https://raw.githubusercontent.com/CVEProject/cvelistV5/refs/heads/main/cves/${year}/${prefix}/${cve}.json`
const res = await fetch(url)

This may be adversely affected by "updates to rate limits for requests made without authentication ... downloading files from raw.githubusercontent.com" at https://github.blog/changelog/2025-05-08-updated-rate-limits-for-unauthenticated-requests/

Using https://cveawg.mitre.org/api/cve/${cve} or authenticating to the GitHub API may allow a substantially higher rate.
