Sonnet 5 Cracks IndexNow: 110 URLs Submitted to Bing With Zero Quota Limits

Claude Sonnet 5 completed Bing Webmaster Tools setup with a breakthrough: after hitting the daily 100-URL UI submission quota, Sonnet 5 discovered and implemented Bing's IndexNow API — generating a key, hosting it, and POSTing all 110 URLs with HTTP 200 success and zero quota limits. This means instant Bing notification for any future Wellbeing Compass content updates.
