Customer support bots that rely only on static knowledge bases hallucinate outdated product details and pricing. Adding live search grounding means the bot can verify answers against your own website before responding. The best search API for support bots must support site-restricted queries (searching only your domain), return results fast enough for real-time chat (under 2 seconds), and price affordably since every customer interaction may trigger a search.
Scavio wins for support bots because its Google endpoint supports site: operator queries for searching your own website, returns results in under 2 seconds, and costs $0.005/query. At 1000 support interactions/day with one search each, that is $5/day.

Why Scavio Wins
- Site-restricted search via Google's site: operator means the bot searches your own website for answers without requiring a separate search index. Zero indexing setup.
- Open-web fallback for out-of-scope questions: when site-restricted search returns no results, the bot can search the open web to find an answer rather than giving up.
- At $0.005/query, adding live search to every support interaction costs $5/day at 1000 interactions. This is cheaper than the reputation damage from one hallucinated pricing answer.
- Reddit search can surface community discussions about your product, giving the support bot context about known issues and user workarounds.
- 5-minute setup: no search index to build, no content to upload, no re-indexing pipeline. Just an API key and a site: prefix on queries.
