What to Expect During the maintenance window: - Requests to logo.clearbit.com will return an error. - No logo assets will be served from calls made to logo.clearbit.com during this period. Why This Is Happening Clearbit announced in March 2025 that the free Logo API will be fully discontinued on December 8, 2025. Despite ongoing communications, usage remains high. This planned brownout is a proactive step to ensure developers notice the deprecation before service ends permanently. Need Help?
