AI Chat Applications

Overview

Most general AI chat apps connect to TokenLab through the standard OpenAI-compatible chat path. In practice that means:

use https://api.tokenlab.sh/v1 as the base URL unless the app explicitly asks for a full endpoint URL
use your TokenLab API key as the OpenAI-style API key
pick models that the app can use in a standard chat workflow

General chat apps are usually chat-completions oriented, not Codex Responses WebSocket clients. For Codex CLI/App, Cursor, or other coding tools that need Responses-specific behavior, use the dedicated integration guides instead.

customEndpoints:
  - name: TokenLab
    apiKey: '${OPENAI_API_KEY}'
    baseURL: 'https://api.tokenlab.sh/v1'
    models:
      default: ['gpt-5.4-mini', 'gpt-5.4', 'claude-sonnet-5']

Safer Model Defaults

Category	Suggested Models
General default	`gpt-5.4-mini`, `gpt-5.4`, `gpt-5.5`
Anthropic	`claude-sonnet-5`, `claude-opus-4-8`, `claude-fable-5`
Google	`gemini-3.5-flash`, `gemini-3.1-flash-lite`
DeepSeek	`deepseek-v4-flash`, `deepseek-v4-pro`

Tips

Prefer base URL when the app supports it

Most apps are easier to configure and less fragile when you provide https://api.tokenlab.sh/v1 as a base URL instead of a full endpoint URL.

Use smaller models first

Start with gpt-5.4-mini or deepseek-v4-flash for everyday chat, then move heavier reasoning tasks to gpt-5.4 or claude-opus-4-8.

Keep coding tools separate

General chat apps and coding agents often need different endpoint behavior. Keep Codex/Cursor-style tools on their dedicated integration pages.

Troubleshooting

Connection Error

Verify the base URL is exactly https://api.tokenlab.sh/v1
Remove trailing slashes if the app auto-appends paths
If the app wants a full endpoint URL, use https://api.tokenlab.sh/v1/chat/completions

401 Unauthorized

Double-check your API key
Confirm the key is active in TokenLab dashboard
Make sure there are no extra spaces or line breaks

Model Not Available

Verify the model name exactly
Try a widely supported default like gpt-5.4-mini, deepseek-v4-flash, or claude-sonnet-5
Check current availability in TokenLab docs or dashboard
