SupaStore
One API key for 40+ AI model providers.
SupaStore is an AI API gateway built on New API that aggregates 40+ upstream AI model providers behind a single, OpenAI-compatible API. Developers manage one API key and one balance instead of juggling dozens of provider accounts, keys, and billing relationships. It is built for developers and teams who want real provider choice, redundancy, and cost control without changing their existing OpenAI-style code.
Key Features & Capabilities
Core highlights, automation workflows, and capabilities offered by this tool
OpenAI
compatible unified API: Access supported models from OpenAI, Anthropic, Google, DeepSeek, and other vendors through one endpoint, reducing the need to maintain separate provider integrations.
Intelligent routing and automatic failover
Configure multiple upstream channels with priorities and weights; SupaStore can retry requests through available channels when an upstream hits rate limits (429) or server errors (5xx).
Native streaming and prompt
cache support: Streams reasoning tokens as they are returned upstream and passes through provider caching mechanisms, including Anthropic Prompt Caching, DeepSeek context caching, OpenAI cached tokens, and Gemini caching.
Team
level governance and token billing: Set user-group channel affinity, maximum token safety limits, and quota allocations, then review granular token-level billing logs alongside measured model latency and success-rate data.
AI product teams, backend developers, agent builders, platform engineers, and organizations managing multi-model LLM usage across applications and developer tools.
How It Works (Step-by-Step)
The end-to-end user journey from input to automated output
Step 1
Generate an API key and point an OpenAI-, Anthropic-, or Gemini-compatible client or framework to SupaStore by replacing its base_url.
Step 2
Send model requests through SupaStore's unified gateway, which routes requests to supported providers such as OpenAI, Anthropic, Google, and DeepSeek.
Step 3
Receive streamed inference tokens while the gateway applies provider prompt caching, load balancing, usage-based billing, and automatic failover for rate-limit or server errors.
