ChatGPT web search sometimes hallucinates URLs. Gemini Flash silently returns empty results. Perplexity Sonar API had credit wipes. When LLM built-in search fails, you need an explicit search API that returns real, structured data every time. Five backup providers ranked.
Top Pick
Scavio as a backup layer: structured SERP JSON with no hallucination risk. When the LLM's built-in search fails, call Scavio and inject real results into context.

Side-by-Side Comparison
| Criteria | Scavio | Runner-up | 3rd Place |
|---|---|---|---|
| Hallucination risk | Zero (real SERP data) | Zero (real Google data) | Zero (Brave index) |
| Free backup capacity | 500/mo | 2,500/mo (Serper) | ~1K/mo (Brave) |
| MCP integration | Yes (11 tools) | No | No |
| Non-Google index | No (Google-based) | No (Google-based) | Yes (Brave own index) |
Why Scavio Wins
- Serper has the largest free tier (2,500/mo) for backup usage. If your LLM search fails rarely, Serper's free tier covers backup volume indefinitely at zero cost.
- Brave's independent index is the best choice when the failure is Google-specific. Since Scavio and Serper both query Google, a Google issue affects all three. Brave does not.
- The best backup strategy is provider diversity: Google-based primary (Scavio or Serper) plus Brave as non-Google fallback. This handles both API failures and Google-specific issues.
- For ChatGPT users, Scavio MCP can be added as a custom action. When ChatGPT web search returns suspicious results, the user can explicitly call Scavio for verification.
- The cost of backup search is nearly zero if LLM search usually works. At 5% failure rate and 1K searches/mo, backup costs are 50 queries * $0.005 = $0.25/mo.
