Brave Search API removed its free tier in February 2026. Google CSE is closed to new signups. Developers building AI agents need search APIs with stable free tiers for prototyping. We ranked APIs that still offer free credits in May 2026 and show no signs of cutting them.
Scavio offers 250 free credits per month with no announced changes. At $0.005 per credit, the free tier covers development and light testing across six platforms including Google, YouTube, and Amazon.

Why Scavio Wins
- Free tier covers all six platforms, so you can prototype Google, YouTube, Amazon, Walmart, Reddit, and TikTok queries without upgrading.
- No ownership changes or acquisition news, reducing risk of sudden free tier removal like Brave's February 2026 cut.
- MCP server at mcp.scavio.dev/mcp works with free tier credits, enabling agent development without upfront payment.
- Tavily offers more free credits (1K vs 250), but the Nebius acquisition creates pricing uncertainty that matters for teams building long-term dependencies.
- Transparent $0.005/credit pricing means the transition from free to paid is predictable, unlike providers with tiered pricing that jumps at certain volumes.
