Microsoft Security Response Center (MSRC) API not working for you?

  1. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
  2. If calls fail only in the browser with a CORS error, Microsoft Security Response Center (MSRC) may not allow cross-origin requests. Call it from your server instead.
