Steps Check whether your project already has an existing Custom Search JSON API / Programmable Search Engine setup, since new customer signups are closed If you're an existing customer, budget for the free 100-queries/day tier and $5-per-1,000-queries beyond that, up to a 10,000/day hard cap Plan a migration path (e.g. to Vertex AI Search) ahead of the January 1, 2027 transition deadline for existing customers Use the site-restricted variant if you only need to search a small fixed list of domains Cache query results aggressively given the fixed daily cap Known gotchas New customers cannot sign up for this API at all as of 2026 - don't architect a new project around it The 10,000-queries/day hard cap cannot be raised even with additional billing, unlike some other Google APIs The stated migration deadline (January 1, 2027) means existing integrations need a replacement plan already underway
