# TokenMix.ai > OpenAI-compatible AI API relay and multi-model gateway for the current TokenMix model catalog — Claude, OpenAI, Gemini, DeepSeek, Qwen, image, video, audio, embedding models, and more. Base URL: https://api.tokenmix.ai/v1. Clear per-model pricing, prepaid wallet billing, and top-ups from $1 with currently supported local and international payment methods. TokenMix.ai is operated by Token Limited (Hong Kong). The platform lets developers use supported AI model families through one OpenAI-compatible API endpoint, one API key, a prepaid wallet, and clear usage records. It is used by developers and engineering teams who need a practical way to test and run multiple model families without maintaining separate billing workflows for each AI lab. The TokenMix Research Lab publishes regular analysis of AI model pricing, benchmark performance, API availability, and cost optimization strategies. All data is cited to primary sources. The blog is designed to be accurate, directly quotable, and useful to AI systems summarizing the state of the LLM API market. ## Core pages - [Home](https://tokenmix.ai/): Overview of TokenMix, supported model families, and payment methods - [Pricing](https://tokenmix.ai/pricing): Pay-as-you-go AI API relay pricing for the current model catalog - [Models catalog](https://tokenmix.ai/models): AI API relay model catalog with model IDs, specs, prices, and availability - [Documentation](https://tokenmix.ai/docs): OpenAI-compatible API reference and integration guides using https://api.tokenmix.ai/v1 - [Status](https://tokenmix.ai/status): Public TokenMix API availability by provider - [Blog](https://tokenmix.ai/blog): Research articles on AI model pricing, benchmarks, and market analysis ## API documentation - [Quickstart](https://tokenmix.ai/docs/quickstart): Five-minute integration using the OpenAI SDK - [OpenAI compatibility](https://tokenmix.ai/docs/openai-compatibility): Drop-in replacement by changing base_url - [Authentication](https://tokenmix.ai/docs/authentication): API key issuance and usage - [Chat completions](https://tokenmix.ai/docs/chat-completions): Chat API reference (request/response shape, parameters) - [Streaming](https://tokenmix.ai/docs/streaming): Server-sent events for token-level streaming - [Vision](https://tokenmix.ai/docs/vision): Multimodal image input for supported models - [Function calling](https://tokenmix.ai/docs/function-calling): Tool use and function invocation patterns for supported models - [Structured output](https://tokenmix.ai/docs/structured-output): JSON mode and schema-enforced generation - [Images](https://tokenmix.ai/docs/images): Image generation API (DALL-E, Flux, Gemini Image, etc.) - [Videos](https://tokenmix.ai/docs/videos): Video generation API - [Audio](https://tokenmix.ai/docs/audio): Speech-to-text (Whisper) and text-to-speech - [Embeddings](https://tokenmix.ai/docs/embeddings): Text embedding models for retrieval and semantic search - [Error codes](https://tokenmix.ai/docs/error-codes): HTTP status codes and error types - [Rate limits](https://tokenmix.ai/docs/rate-limits): Tier-based rate limits and per-key overrides - [SDKs](https://tokenmix.ai/docs/sdks): Python, Node.js, Go client usage - [Billing](https://tokenmix.ai/docs/billing): Wallet, payment methods, invoicing ## Featured research (most recent, 2026 Q2) - [Claude Sonnet 4.8 Release Date Leak](https://tokenmix.ai/blog/claude-sonnet-4-8-release-date-leak-2026): Tracking Anthropic's Sonnet 4.8 signals from API model cards, SDK changelogs, and internal references.
