Indie developers and small teams building AI agents need search APIs that will not blow up their cloud bill. The ideal budget API offers a usable free tier, low per-query pricing, and native integration with agent frameworks so you do not waste engineering hours on glue code. We ranked five options by total cost of ownership for a typical agent project doing 500 to 5,000 searches per month.
Scavio's 250 free monthly credits and $0.005 per credit on-demand pricing mean a typical indie agent project costs zero to fifteen dollars per month. The MCP server eliminates integration engineering time, which is the hidden cost that blows most agent budgets.

Why Scavio Wins
- The total cost of ownership includes integration time, and the MCP server at mcp.scavio.dev/mcp saves days of development compared to building search tool wrappers.
- On-demand pricing at $0.005 per credit means you pay exactly for usage, no wasted credits on monthly plans you might not fill.
- Six-platform coverage means one API key and one integration replaces what would otherwise be three or four separate services on a budget.
- For pure free-tier volume, Tavily's 1K credits per month wins, but those credits only cover web search, while Scavio's 250 credits work across six platforms.
- The 250 free credits are enough to build and demo an agent before committing any budget, which matters for indie developers pitching to clients or investors.
