 "repo_slug": "respanai-respan-gateway",
 "title": "Call any model from the SDK you already use",
 "page_title": "How to call any model from the SDK you already use with Respan Gateway",
 "summary": "Point an existing OpenAI, Anthropic or Gemini SDK at the gateway to reach other vendors' models.",
 "who": "A developer whose app is built on one vendor's SDK and who wants to try or switch to a model from another vendor without rewriting the calls.",
 "problem": "Each vendor has its own API format, so switching models usually means changing client code.",
 "outcome": "The existing SDK keeps working unchanged and reaches a model from another vendor through the gateway's local endpoint.",
 "steps": [
  "Install the gateway with `pip install respan-gateway`.",
  "Set a vendor key in your shell with `export OPENAI_API_KEY=sk-...`.",
  "Start the gateway by running `respan-gateway`.",
  "In your app, create the client with base_url set to http://localhost:8080 and call a model such as gpt-6-luna, as in the README example.",
  "Open http://localhost:8080/ui/ to confirm the request appears in the live log."
 ],
 "agent_prompt": "In the respan-gateway repo, start the gateway with the OPENAI_API_KEY from the environment, then send one chat request through http://localhost:8080 using the Anthropic SDK with model <target-model>. Return the reply text, and verify that the request appears in the live log at localhost:8080/ui/.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "The gateway answers only on loopback unless client keys are configured, and it refuses to start on a public address without them.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "rust",
 "requirements": [
  "Python with pip, or a Rust toolchain with cargo, or Docker",
  "An API key for at least one model vendor, such as OPENAI_API_KEY",
  "An existing app or SDK that accepts a custom base URL",
  "Optional: a Respan API key for tracing and a tool vendor key for MCP tools"
