Everything about API integration, supported models, billing, and account security.

Product & Features
LingCore is a multi-model AI API gateway that provides unified OpenAI-compatible access to GPT, Claude, Gemini, Grok, Codex, and other AI models. One API key — no need to manage separate accounts for each provider.
Currently: OpenAI (GPT-5.5, GPT-5.4, GPT-5.4-mini, image generation), Anthropic (Claude Opus 4.8, Sonnet 4.6, Fable 5), Google (Gemini 2.5 Pro, 2.5 Flash, 3.x series), and xAI Grok, with more models added continuously.
Fully compatible. Change your base_url to https://api.lingcoreai.com/v1 and your existing OpenAI SDK code works unchanged for GPT, Claude, Gemini, Grok, and all other supported models.
LingCore's core value: one key for all providers, automatic failover, transparent usage tracking, no need to register with each vendor separately.
Integration & Setup
Set two environment variables: export ANTHROPIC_BASE_URL=https://api.lingcoreai.com and export ANTHROPIC_API_KEY=<your LingCore key>. Then use Claude Code as normal — no other changes needed.
Pass base_url when constructing the client: client = openai.OpenAI(api_key="<your key>", base_url="https://api.lingcoreai.com/v1"). All subsequent API calls work identically to the official SDK.
In Cherry Studio's API settings, set the API endpoint to https://api.lingcoreai.com/v1 and enter your LingCore API key. All supported models will be available to select.
Yes. Call https://api.lingcoreai.com/v1/messages with the anthropic-version: 2023-06-01 header and your LingCore key to use Claude models via the native Anthropic Messages format.
Yes. Call https://api.lingcoreai.com/v1beta/models/{model}:generateContent with your LingCore key. The request format is identical to the official Gemini API.
Account & Billing
No. Register for free and top up your balance only when you are ready to make API calls. No payment method required to create an account.
You are charged per token consumed. Prices are listed per million tokens (1M tokens ≈ 750,000 words). Your usage dashboard updates in real time with per-call cost breakdowns.
No. Your top-up balance has no expiry date and remains valid indefinitely.
Alipay, WeChat Pay, and USDT (cryptocurrency) are supported. There is no minimum top-up amount.
Reliability & Security
LingCore routes and automatically fails over across multiple upstream provider nodes. A failure at one provider does not affect your service. The system monitors each model in real time and switches automatically on any anomaly.
LingCore acts as a transparent proxy. Only token usage and model information are recorded for billing purposes. The content of your API requests is not stored.
Log in to the dashboard immediately and disable or delete the compromised key from the API Keys page, then generate a new one. We recommend creating separate keys per project and setting usage limits.
