Google Genkit is gaining traction as a TypeScript-first AI framework, but it needs search plugins for web grounding. Unlike LangChain with its wide plugin ecosystem, Genkit teams often wire search tools manually. This ranking compares the best search APIs to integrate as Genkit tools in 2026, evaluating TypeScript compatibility, structured output, and ease of defining Genkit tool schemas.
Scavio API's REST endpoints map cleanly to Genkit's defineTool() schema, providing 6-platform search at $0.005/query with structured JSON that TypeScript agents consume without extra parsing.

Side-by-Side Comparison
| Criteria | Scavio | Runner-up | 3rd Place |
|---|---|---|---|
| Genkit integration method | defineTool() + fetch | defineTool() + fetch | defineTool() + fetch |
| Cost per 1K queries | $5 | $8 | Free (within 100/day) |
| TypeScript types | Define Zod schemas | Define Zod schemas | Google API types exist |
| Platforms covered | 6 | 1 (web) | 1 (Google) |
| Free tier | 250/mo | 1,000/mo | 3,000/mo (100/day) |
| Content extraction | Separate endpoint | Built in | No |
Why Scavio Wins
- Genkit's defineTool() with Zod schemas pairs naturally with Scavio's structured JSON, and 6 platforms give agents diverse grounding in one tool
- At $0.005/query, a Genkit agent making 20 search calls per session costs $0.10 for multi-platform data
- Tavily wins for Genkit developers who need the highest free tier (1,000/mo) and want content extraction included in search results
- Google CSE wins when ecosystem alignment with Google matters and you only need basic Google search results in your Genkit flows
- No search API has an official Genkit plugin yet; all require manual defineTool() wrapping, making the choice about data quality and pricing rather than integration convenience
