Connect the ZaitXCode AI API
One endpoint, one key, and every model behind it: 29 free providers plus OpenRouter, with your plan's limits applied automatically. The API speaks the OpenAI format, so the official SDKs and every editor that speaks OpenAI work with it unchanged.
1 · Get your key
Sign in on zaitxcode.com, open your account page and create a key in the API Keys section. The key is an AI API key: it can only reach the AI endpoints (chat, models and usage) — never your account, the admin API or the billing. Copy it when it is shown: it is never displayed again.
Open the account page2 · The base URL
Every request goes to this base URL with the key in the Authorization header.

}'4 · Use it in your editor
Every editor that speaks the OpenAI API works with the same base URL and key (VS Code with Continue or Cline, JetBrains, Cursor, Zed, …). Set:
Base URL: https://api.zaitxcode.com/v1 API Key: sk_gw_… (the key from your account page)
5 · The plans
One subscription covers the chat on the site and this API — the same plan, the same limits. The free providers are always tried first; a paid model is only reached by the paid plans.

The maximum: 4K media, the strongest models
6 · A few rules
- Never put the key in the browser of a public app — put it on your server.
- The key is scoped to the AI API: it cannot reach anything else.
- The free providers are tried first; the paid ones only for the paid plans.
- Every plan has a daily request cap and a token budget — /v1/plan shows yours.
