API Quick Start
Get your first API call running in minutes. TokenPort uses an OpenAI-compatible endpoint — if you have existing OpenAI SDK code, migration is a two-line change.
Quick Start
Request API Access
Submit your application at tokenport.ai/pricing. Our team will verify your overseas entity status and arrange dedicated private line connectivity.
Receive Your API Key
Once your private line is established, you will receive your API key and base URL via secure email. Store your key securely — it grants access to your account.
Make Your First Call
Update your base URL and API key in your existing code. The endpoint is fully OpenAI-compatible — no other changes required.
Example: cURL Request
Replace YOUR_API_KEY with your TokenPort API key and YOUR_PRIVATE_LINE_HOST with the host provided during onboarding.

Token Calculation
Tokens are the basic unit of text processed by the model. As a rough guide, 1 token ≈ 4 characters in English, or approximately 1.5–2 Chinese characters.
Both your input (prompt + system message + conversation history) and the model's output are counted and billed separately. Check your token usage dashboard for real-time consumption data.
To estimate costs: multiply your expected input tokens by the input token rate, and your expected output tokens by the output token rate. See the Pricing page for current rates.
