How to send one API call to many models from a script with Omni Route

Point any OpenAI-style client at one local endpoint and switch models without changing code.

Credentials. The script needs your Omni Route key, so keep it in an environment variable and out of shared code.

Who it is forA developer or analyst writing a script or small app that calls AI models and wants to test several providers without rewriting the client.

The problemEvery provider has a different SDK, base URL and key handling, so trying a new model means new integration work.

The outcomeA single chat completion request to localhost returns a model answer, and the model can be changed in one field.

What you need first

  • Node.js/npm or Docker to run OmniRoute (both are listed in the README)
  • Accounts with the AI providers you want to connect, plus their credentials where required
  • A terminal and a browser to open the local dashboard

Steps

  1. Install Omni Route with npm (npm install -g omniroute) or pull the Docker image diegosouzapw/omniroute. (inferred, check the README)
  2. Connect a provider in the dashboard and copy your Omni Route key from Dashboard → Endpoints.
  3. Run the test request: curl http://localhost:20128/v1/chat/completions -H "Authorization: Bearer YOUR_OMNIROUTE_KEY" -H "Content-Type: application/json" -d '{"model":"auto","messages":[{"role":"user","content":"Hello!"}]}' (inferred, check the README)
  4. Open examples/quickstart/ in the repo and pick the Python or Node.js script for your project.
  5. Replace the model value with a specific model ID from your connected providers when you want a fixed model.

Prompt for your agent

Using the diegosouzapw/OmniRoute repo, write a script that sends the prompt <prompt> to http://localhost:20128/v1/chat/completions with model auto and prints the reply. Run it and report the reply text. Verify that the HTTP status is 200 and the reply is non-empty.

Caveat. The README says a fresh installation can have no eligible keyless targets, so the first request may fail until a provider is connected.
