Content, sources and update rules

The goal of this set of documentation is to help users verify configurations, not to replace technical descriptions with unverifiable blurbs.

Content scope

These docs serve AIFast Link GPT, Claude and Gemini API users. They cover usage-based funding, group-specific monthly plans, OpenAI-compatible endpoints, Anthropic Messages and Gemini protocol boundaries. Accounts, model access and billing refer to Link; a listed model is not automatically covered by every plan.

fact check

For client fields, please refer to the public documentation of the corresponding product first; for HTTP status codes, refer to the standard RFC; for AIFast addresses, models and authentication methods, refer to the API documentation and console.

Dynamic information

Link plans currently reset daily; a 30-day term does not mean unlimited usage. Check both plan settings and billing preferences for exhaustion behavior. Price snapshots include their verification date; balances, keys and test records from other sites do not directly apply to Link.

How we write a tutorial

First give the scope of application and the prerequisites of the agreement.
Verify authentication, address, and model using minimal requests.
Distinguish between basic chat, streaming output, tool invocation, and multimodal capabilities.
Specifies the status code, response body, and request ID that should be saved on failure.
Attached are verification dates and public sources.

Documentation does not make promises

There is no promise that all models will be permanently available or that prices will never change.
Don't write "OpenAI Compatible" as "fully compatible with all OpenAI features."
Agents, tool calls, and long tasks are all available without inferring the success of a single chat.
It is not recommended to save API Keys in public code, front-end pages, or screenshots.
