One endpoint for OpenAI, Anthropic, Gemini, Mistral and DeepSeek

Operate every model from one refined gateway.

API5D gives your team a single OpenAI-compatible surface for chat, generation, billing, routing and usage analysis without stitching providers together by hand.

Performance

Fast proxy path

Low-latency routing, pooled upstream connections and predictable request flow for production traffic.

Compatibility

OpenAI-style API

Keep existing SDKs and tools. Point them at API5D and switch providers behind the same contract.

Observability

Cost visibility

Track requests, token spend and model-level usage without building a separate internal console.

Quick Start

Drop in one base URL.

Run existing client code against API5D and keep routing, billing and governance in one place.

curl /v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-4o",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Endpoint

Modes

Chat, image, video, TTS and STT from one workspace.

Ops

Keys, balances and usage remain attached to the same account surface.
