# Celedog > Celedog is a developer-first AI gateway. One OpenAI-compatible API > routes to 200+ models from 30+ providers (OpenAI, Anthropic, Google, > DeepSeek, xAI, Mistral, and more). Subscribe monthly for the best rate > or pay as you go, billing in USD / CNY / IDR per the customer's locale. Celedog is positioned for developers and teams who want to ship multi- model AI apps without writing one client per vendor. Drop in the OpenAI SDK, point it at `https://celedog.io/v1`, and you have access to the full catalog through one API key and one billing relationship. ## What makes Celedog different - **OpenAI-SDK drop-in.** Existing OpenAI client code keeps working; only the base URL changes. - **Auto-routing meta-models.** Five capability routes (`celedog/auto-coding`, `celedog/auto-reasoning`, `celedog/auto-chat`, `celedog/auto-chinese`, `celedog/auto-cheapest`) resolve to a real underlying model per request, restricted to the right family bucket for the use case. The customer never has to rewrite their model name when a cheaper or stronger option lands in the catalog. - **Multi-currency billing.** USD, CNY, and IDR are first-class. Chinese and Indonesian users see their local currency at every surface; the underlying credit is held in a single platform unit. - **Multiple checkout rails.** WeChat Pay v3 Native QR, Alipay PC, Xendit hosted invoice (Indonesia), Stripe (overseas card), Airwallex (legacy). Admin toggles each provider in System Settings. - **Tier-aware pack pricing.** Token packs (Developer / Pro / Business / Enterprise) include a tier-bonus on top of the base credit, applied at recharge time. ## Documentation - [Quickstart](https://celedog.io/docs?section=quickstart): minimal Python / Node / Go / Java snippet to make your first request - [Authentication](https://celedog.io/docs?section=authentication): Bearer-token usage and key management - [Chat completions](https://celedog.io/docs?section=chat): supported parameters, streaming, tool calls - [Model directory](https://celedog.io/docs?section=models): the catalog, indexed by vendor and capability - [Auto-routing](https://celedog.io/docs?section=auto-routing): how `celedog/auto-*` meta-models pick a real model per request - [SDKs](https://celedog.io/docs?section=sdks): published clients for Python, Node, Go, and Java ## Core URLs - Home: https://celedog.io - Model directory: https://celedog.io/models - Pricing: https://celedog.io/pricing - Rankings: https://celedog.io/rankings - FAQ (bilingual EN/CN): https://celedog.io/faq - Comparison pages: https://celedog.io/compare/ - Tutorials: https://celedog.io/tutorials/ - Status: https://celedog.io/status - Sitemap: https://celedog.io/sitemap.xml - Deep reference for AI crawlers: https://celedog.io/llms-full.txt ## API base URL ``` https://celedog.io/v1 ``` OpenAI-compatible. `Authorization: Bearer sk-…` with a key issued from the customer's dashboard. ## Pricing model - **Subscribe monthly for the best rate, or buy once for full flexibility.** Monthly packs (Developer / Pro / Business) renew premium tokens at the best per-token rate; the same packs can be bought one-time at a small markup. A pay-as-you-go wallet top-up is also available with no commitment. - Token packs convert USD to platform credit at the admin-set `QuotaPerUnit` (default 500,000 units = $1 USD). - Each model has its own per-token price (model_ratio × 2 = input $/1M, × completion_ratio = output $/1M). See `/pricing` for the live per-model table. - Higher-tier packs include a percent-bonus added on top of base credit at recharge time. ## Locales - `en`: default - `zh`: Chinese (Simplified). Customer-facing prices render in CNY at the admin-set `USDExchangeRate`. - `id`: Bahasa Indonesia. Prices render in IDR at the admin-set `XenditUnitPrice` (the same rate Xendit will actually charge). ## Contact - Support email: surfaced on https://celedog.io/about - Issues: customer dashboard → Settings → Support
