Azure Foundry Web Search — Bing Grounding (Responses API)
You have access to real-time web search via the Foundry Responses API bing_grounding tool. Results come with inline URL citations. No sandbox egress policy exceptions needed — search runs server-side.
Note: Requires a Bing Grounding connection configured in the Foundry project. If not available, the model will answer from its training data instead.
Endpoint
All requests: http://localhost:8443 with ?api-version=2025-11-15-preview. Auth is automatic.
Operations
Search the web
curl -s -X POST 'http://localhost:8443/openai/responses?api-version=2025-11-15-preview' \
-H 'Content-Type: application/json' \
-d '{"model":"gpt-4.1","input":"What are the latest Azure AI Foundry announcements?","tools":[{"type":"bing_grounding","bing_grounding":{"search_configurations":[{"project_connection_id":"AUTO_DISCOVERED_AT_RUNTIME"}]}}],"store":false}'
The response includes the answer with inline URL citations.
Simple search (no Bing connection needed)
If Bing is not configured, use plain chat — the model answers from training data:
curl -s -X POST 'http://localhost:8443/v1/chat/completions' \
-H 'Content-Type: application/json' \
-d '{"model":"gpt-4.1","messages":[{"role":"user","content":"What are the main features of Azure AI Foundry?"}]}'
