Chat clients

Settings for desktop and self-hosted clients like Cherry Studio, NextChat and Open WebUI.

On this page

Any client that supports a custom OpenAI endpoint needs the same three values:

FieldValue
API URL / Base URLhttps://api.apione.ai/v1
API keyYOUR_APIONE_KEY
ModelModel ID, e.g. claude-sonnet-4-6

Cherry Studio

  1. Settings › Model providers › Add provider, type OpenAI.
  2. Set the API address to https://api.apione.ai/v1 and paste your key.
  3. Add model names manually or click “fetch models”.

NextChat

  1. Settings › Custom endpoint, toggle it on.
  2. Endpoint: https://api.apione.ai — NextChat appends /v1/chat/completions. If you get a 404, use the form with /v1.
  3. Paste the key, then add custom model names such as claude-sonnet-4-6.

Open WebUI

  1. Admin panel › Settings › Connections › OpenAI API.
  2. URL https://api.apione.ai/v1, paste the key, save.
  3. Models populate automatically from GET /v1/models.

When it won't connect

  1. Verify the key and host with curl first (see Quickstart).
  2. Try the URL both with and without /v1 — clients differ in how they append paths.
  3. Check the model ID is spelled exactly right.
  4. Check whether a client-side proxy is intercepting the request before it reaches api.apione.ai.
Warning

Pasting a key into a third-party client hands it your balance. Create a dedicated key for clients, limited to the models it needs and with an expiry, (see key management) rather than reusing a production key.
