How long does the integration take?

Change one base URL in an OpenAI-compatible client, or install the Python or TypeScript SDK; the quickstart routes a first request in a few minutes.

Will this lock us into another vendor?

No. The router is Apache-2.0 open source, your provider keys stay yours, and the API is OpenAI-compatible, so leaving is a change of base URL.

What happens when a provider fails?

The router falls back to the next model your policy allows and records the fallback in the trace, so an outage costs a retry, not an incident.

If you write the code

One call, the whole decision, in your language.

“How do I send one request and see why it went where it went?”pip or npm install, or just point your OpenAI client at a new base URL. Every answer carries the target, the confidence, the alternatives, the cost and a trace id; report the outcome and the next decision moves. Claude, Cursor and VS Code can call the same router over MCP.

Your existing client - one base URL changedpython

from openai import OpenAI

client = OpenAI(
    base_url="https://opensmartroute.ai/v1",
    api_key=os.environ["OSR_API_KEY"],
)
reply = client.chat.completions.create(
    model="auto",                 # the router picks
    messages=[{"role": "user", "content": prompt}],
)

What comes back next to the answerjson

{
  "model": "gpt-oss-20b",
  "osr": {
    "target": "llm-small",
    "confidence": 0.94,
    "cost_usd": 0.0021,
    "reason": "short rewrite, general domain, no PII",
    "trace": "/platform/dashboard/activity/req_8f3a"
  }
}

No application rewrite. The same call also speaks the Anthropic Messages API, and the Python and TypeScript SDKs return the full decision - ranked candidates, policy rejections, prices - when you want more than the answer.
