FAQ
APIMart is a unified AI API platform providing access to 500+ AI models through a single API. Access Chat APIs (GPT-5, Claude Sonnet 4.5), Video APIs (Sora 2, Veo 3), and Image APIs (Flux.1, Nano Banana) with OpenAI-compatible integration and lower costs than competitors.
APIMart offers up to 70% cost savings compared to Fal.ai, Replicate, and direct providers. Pay-as-you-go pricing with no monthly minimums or hidden fees. Volume discounts apply automatically based on usage.
Simple integration: 1) Sign up and create an API key (no credit card required), 2) Update your base_url to APIMart's endpoint, 3) Start using the OpenAI-compatible format. For OpenAI users, it's just a one-line code change with comprehensive documentation and examples.
With APIMart, you only need to manage one account and one invoice to access 500+ AI models. No more maintaining separate API keys for Claude, OpenAI, and Google. Plus, we offer more competitive pricing than official providers.
Your keys are encrypted in our database. You can generate new keys or revoke old ones at any time in the console to keep your account secure.
APIMart supports multiple mainstream payment channels: Antom (Visa, Mastercard, Alipay), Crypto, PayPal, and Creem. After selecting a plan in the console, you can pay through the channels available in your region. All top-up records can be queried and exported from the billing page. For official electronic invoices or corporate bank transfers, please contact our support team for assistance.
APIMart is fully compatible with the OpenAI API specification, so the official OpenAI client libraries (Python, Node.js, Go, Java, PHP, C#, Ruby, etc.) work out of the box—just swap the base_url, no extra dependencies required. We also support mainstream frameworks like LangChain, LlamaIndex, and Vercel AI.
Default accounts come with generous RPM/TPM quotas, and enterprise accounts can request dedicated quotas and isolated channels. We commit to 99.9% availability, using multi-region multi-provider automatic routing and failover to mitigate single-point risks, with a real-time status page and usage monitoring.
No. APIMart only forwards your request to the selected model provider for the current inference; we never retain your inputs or outputs to train any model. We also pass through each provider's zero data retention (ZDR) agreements, and enterprise accounts can sign a DPA to meet GDPR, SOC 2, and other compliance requirements.
