Doubao Provider

May 10, 2026 · View on GitHub

Doubao tracks Volcengine Ark request-limit headers by probing the chat-completions endpoint with a configured API key.

Setup

  1. Enable Doubao in Settings → Providers.
  2. Paste an API key in the provider settings, or set ARK_API_KEY, VOLCENGINE_API_KEY, or DOUBAO_API_KEY.
  3. Refresh provider usage.

Behavior

  • Endpoint: POST https://ark.cn-beijing.volces.com/api/coding/v3/chat/completions
  • Probe models: doubao-seed-2.0-code, doubao-1.5-pro-32k, doubao-lite-32k
  • Reads x-ratelimit-remaining-requests, x-ratelimit-limit-requests, and x-ratelimit-reset-requests when returned.
  • If the key is valid but rate-limit headers are missing, CodexBar shows the key as active and links to the dashboard for details.
