  No published rate limits. 23andMe currently documents no public API, so there is no
  reference page on which limits could be stated. The 642-URL sitemap at
  www.23andme.org contains no developer, API or reference page; llms.txt lists no API;
  and the only developer surface the company still links — https://api.23andme.com/dev/
  — answers a Cloudflare managed challenge (HTTP 403, cf-mitigated: challenge) to
  anonymous requests, so any limits documented behind it could not be read. This is a
  recorded absence, not an assertion that no limits are enforced.
