The Problem
AI agents fail silently when their search provider goes down. Gemini API returned frequent 429 and 503 errors in May 2026. Agents without fallback chains hallucinated responses during the outage because they had no grounding data.
The Scavio Solution
Chain 2-3 search providers in priority order. Wrap each call with timeout, retry (exponential backoff), and fallback logic. Track provider health scores over time. Route queries to the cheapest healthy provider. Use cached results as the final fallback.
Before
Before the fallback chain, a customer support agent used Gemini grounding exclusively. During a 3-hour Gemini outage, the agent confidently told users incorrect product prices because it hallucinated without grounding data. 847 queries went ungrounded.
After
After implementing the fallback chain (Gemini -> Scavio -> cache), the same outage routes 847 queries through Scavio at $4.24. Zero users see hallucinated responses. The chain auto-recovers when Gemini comes back online. Monthly fallback cost averages $12 for near-100% search availability.
Who It Is For
Agent developers building production systems who need search availability guarantees even when individual providers have outages.
Key Benefits
- Zero search failures during single-provider outages
- Automatic routing to cheapest healthy provider
- Exponential backoff prevents thundering herd on recovery
- Health score tracking detects degradation before full outage
- Fallback costs are marginal (under 5% of queries typically)
