GatewayAgent Frameworks

Strands Agents (gateway)

Route Strands Agents model calls through the Respan gateway to use models and provider credentials configured in Respan. The OpenAI-compatible model adapter points at Respan’s gateway endpoint with RESPAN_API_KEY.

Setup

1

Install packages

$pip install "strands-agents[openai]"
2

Set environment variables

$export RESPAN_API_KEY="YOUR_RESPAN_API_KEY"
$export RESPAN_BASE_URL="https://api.respan.ai/api"
$export RESPAN_MODEL="gpt-5-mini"

No provider credentials are needed in your application; the Respan gateway handles provider authentication.
