Should the API host include /chat/completions?

No. Use https://omnimodel.me/v1; the app adds the endpoint path itself.

The app shows no models. What should I check?

GET /v1/models returns only models your key can call. Check the key's allowed models, or type the model ID manually.

Can I use my key in a web page or extension?

In personal clients and extensions, yes, but never in publicly shipped frontend code. Give each app its own key with a spend limit.

Apps

Updated 2026-09-23

Almost any app that speaks the OpenAI-compatible API can connect directly. The app gallery has step-by-step setups for popular chat clients, coding assistants, workflow tools, browser extensions and official SDKs, and fills in your key after you sign in.

The three settings you need

Nearly every app asks for just these:

Setting	Value
API host (Base URL)	`https://omnimodel.me/v1`
API key	A `key_...` key created on the console Keys page
Model	A model ID from the catalog

Choose OpenAI-compatible as the provider type (some apps call it OpenAI API Compatible or Custom OpenAI). For tools that only speak the Anthropic or Gemini protocol, use https://omnimodel.me/anthropic or https://omnimodel.me/v1beta instead.

Choosing by app type

Type	Typical use	Tip
Chat client	Everyday chat, switching models	Give the client its own key and limit its models
Coding assistant	Code generation, refactoring, explanations	Pick a long-context model and set a daily spend limit
Workflow	Batch jobs, automation nodes	Set a monthly limit and watch the failure rate in usage
Browser extension	Page translation, quick explanations	Frequent calls, so prefer cheaper models
SDK	Calls from your own backend	Keep the key in server-side environment variables, never in frontend bundles

When the app cannot connect

Make sure the API host ends with /v1, without /chat/completions.
Make sure the key was copied in full and is not paused or revoked (error auth.invalid_key).
Check the model ID for typos, and that it is in the key's allowed models (model.unavailable, auth.forbidden).
If the app's model list is empty, check the key's allowed models: GET /v1/models returns only models that key can call.
