One OpenAI-compatible gateway for 40+ AI providers, 200+ models

[Lyllaisthinking]

SmartAPI: a unified AI model API gateway for developers. Call OpenAI, Anthropic, Gemini, and 40+ providers through a single endpoint and one API key — drop-in compatible with the official OpenAI and Anthropic SDKs.

Why SmartAPI

• One key, many models — a single API key can call any listed model across providers
• Drop-in compatible — reuse the official OpenAI / Anthropic SDKs; only base_url and api_key change
• Built-in routing & failover — requests route to healthy upstream channels, with retries on transient errors
• Transparent proxy — request/response bodies follow upstream provider specs
• Zero data retention — proxy only; prompts and completions are not stored
• Usage-based billing — $1 = 100 credits; chat billed by tokens, image/video by generation (priced per model)
• Low latency — smart routing and connection reuse; P99 < 200ms, 99.9% uptime SLA
