Requests are forwarded to the upstream providers and billed per token at a published fraction of each model's official list price. The discount comes from the way upstream capacity is purchased, not from serving different or reduced models — the model, context window and speed are the provider's own. ## Endpoints - Base URL for OpenAI-compatible clients: `https://apiclan.us/v1` - Base URL for Claude Code and the Anthropic SDK: `https://apiclan.us` (these clients append `/v1/messages` themselves) - Authentication: `Authorization: Bearer `, keys start with `sk-` ## Key facts - Billing is per token, in USD, with no subscription, no monthly minimum and no per-request token cap. - Each API key belongs to exactly one group. A key made for text models cannot call image models, and vice versa. - Cached input is billed at a fraction of the input rate, so agent tools that resend the same context cost less than raw token counts suggest. - Prices on the site are regenerated automatically from real billing data. ## Pages - [Pricing](https://apiclan.us/pricing): every model, official list price next to what the customer pays, in 14 languages. - [Quickstart](https://apiclan.us/guide): base URL setup for Claude Code, Codex, Cursor, Cline, Roo Code, Cherry Studio, LM Studio and others, plus the model list. - [Legal](https://apiclan.us/legal): terms, refund policy and contact details. ## Per-model pricing pages Each model has its own page at `https://apiclan.us/pricing/`, with the official price, the price here, a cost calculator and a worked example from real billing data. Language variants live at `https://apiclan.us//pricing/` for: zh, zh-Hant, ja, ko, de, fr, es, tr, pt-BR, it, id, vi, ms. ## Contact - Email: support@apiclan.us - Site: https://apiclan.us
