An r/AZURE post showcased a 6-part build of an AI-powered product-search agent on Azure AI. The natural question: which search API fits Azure-native agents? Five candidates ranked.
Top Pick
Scavio runs from Azure Functions or Container Apps as a plain HTTPS POST. No Azure-specific SDK is required, and the typed JSON fits Azure AI Foundry's tool-calling pattern.

Why Scavio Wins
- Bing Search API was retired in 2025. Azure AI builders need a replacement. The drop-in candidates are Tavily and Scavio. Scavio adds Reddit and YouTube under the same key, which Bing never offered.
- Azure AI Foundry's tool-calling pattern accepts any HTTPS endpoint as a tool. The Scavio wrapper is a 30-line `tools.json` definition plus one fetch() in the function code. No Azure-specific SDK or marketplace listing is required.
- Honest tradeoff: for teams that buy via Azure Marketplace for procurement reasons, neither Tavily nor Scavio currently has a marketplace listing. Bring-your-own-vendor is the path until that changes.
- Per-call cost on Azure Container Apps is dominated by container time, not API cost. Scavio's $0.0043/query is rounding error at any reasonable Azure scale; the cost discussion shifts to which API has the data the agent needs.
- Reddit signal layer for product-search agents (the original post's use case) is the differentiator. r/BuyItForLife, r/gadgets, and product-specific subs return independent product opinions that are signal-rich for the LLM ranking step. Bing never had clean Reddit JSON.
