APIMart
APIMart is a unified AI API gateway providing access to 500+ models through a single OpenAI-compatible API. It covers chat, image, video, and audio models including GPT-5, Claude, Sora 2, and Veo, with pay-as-you-go credits, health-aware routing, and savings of up to 70% for production teams.
What is APIMart?
APIMart is a discounted AI API aggregator that gives teams access to 500+ AI models through a single OpenAI-compatible endpoint. The platform positions itself as the AI API layer for production teams: instead of maintaining separate accounts, keys, and invoices for OpenAI, Anthropic, Google, and ByteDance, users create one APIMart key and reach every model family through one interface. The model catalog spans chat models like GPT-5, Claude Sonnet 4.5, and Gemini, image models like Nano Banana, GPT-Image-2, and Imagen, video models like Sora 2, Veo 3, and Kling, and audio models, with pricing tables on the site showing per-model rates in credits, where one credit equals roughly $0.10. APIMart markets savings of up to 70% compared to fal.ai, Replicate, and direct providers, with volume discounts applied automatically. The platform includes health-aware provider routing that directs requests to the best available vendor, unified billing where credits are shared by every model family, monitoring, key management, and failover across providers. Integration is designed to be trivial: OpenAI SDK users change the base URL to APIMart's endpoint and keep their existing code, with documentation and examples for multiple languages. The site also publishes an llms.txt prompt that lets coding agents like Codex, Claude, and Cursor read the full API documentation from a single prompt. Signup requires no credit card, and pricing is pay-as-you-go with no monthly minimums or hidden fees; users top up credits and pay only for successful requests. Payment options include Antom, Visa, Mastercard, Alipay, Crypto, PayPal, and Creem, and enterprise users can request official invoices or bank transfers. APIMart is aimed at startups, production teams, and AI agents that want broad model access at lower operating cost with one account and one invoice. The console provides usage monitoring, key rotation, and billing export, and the docs include SDK examples for Python, Node, and other languages. New models are added regularly to the catalog, and the platform's routing layer keeps services stable even when individual providers experience issues.

Who is APIMart for?
APIMart is built for development teams that consume multiple AI models in production and want to consolidate vendors. Startups use it to access frontier models from OpenAI, Anthropic, and Google without juggling five accounts, saving on operating costs while scaling. AI engineering teams use the OpenAI-compatible endpoint to migrate existing integrations with a one-line change and keep their SDKs. Agent developers connect Codex, Claude, Cursor, and other coding agents to the platform through the llms.txt prompt so agents understand every model and endpoint. Indie developers and freelancers use the pay-as-you-go credits with no monthly minimum to keep AI costs aligned with usage. Cost-sensitive teams that benchmark fal.ai and Replicate pricing use APIMart's volume discounts and health-aware routing to reduce per-request spend. Fintech and e-commerce teams use the unified billing and monitoring to govern AI spend across model families. Teams building video and image pipelines use the Sora, Veo, Kling, and Nano Banana endpoints through the same key. Enterprises in regions where certain payment methods are restricted use the multi-channel payments including Alipay and crypto. Non-technical founders prototype through the docs and dashboard, while support handles recharge and service questions in one flow. QA and testing teams also use the platform to evaluate model outputs across providers, and regional startups use the flexible payment channels to fund accounts where international cards are not accepted.
