Key features	OpenAI-compatible API for open-source frontier models (DeepSeek, Kimi, GLM, MiniMax) Pay-per-token billing with no subscription or minimum monthly commitment Infrastructure hosting removes the need to self-manage GPU deployment for these models Multiple model families available behind a single consistent API interface Pricing starting near $0.105 per million tokens depending on model choice	Single API key across image, video, language and audio models OpenAI and Anthropic SDK compatibility for language models Prepaid USD balance with per-request billing Failed requests are not charged Per-model playground, parameters and docs
Pros	OpenAI-compatible API means minimal code changes for teams already using that interface pattern Pay-per-token pricing avoids paying for idle capacity between usage spikes Access to several current open-source frontier models behind one API instead of managing several accounts	No monthly minimum or subscription Failed requests cost nothing, per the pricing page Model prices are listed on each model page before integrating
Cons	No free tier, every API call consumes paid credit from the first request Usage-based pricing makes monthly cost harder to predict than a flat subscription Limited to open-source model families; no access to closed frontier models like GPT or Claude through this API	Prepaid balance model needs a top-up before any call Third-party routing adds a dependency between the app and the model provider Company details and uptime history are not published on the homepage
