01 / THE PLATFORM

From idea to
production response.

OneModelAPI removes the integration tax between your product and the intelligence it needs. Keep your request format, switch models in seconds, and ship with confidence.

One gateway, every route

OpenAI-compatible endpoints for chat, responses, streaming, embeddings and image generation. One key, one base URL, zero provider rewrites.

Read the quick start

$ curl onemodelapi.com/chat/completions -H "Authorization: Bearer om_live_..." -d '{"model":"claude-sonnet"}'

Smart fallback

Route around rate limits and provider failures automatically, with predictable retries and transparent request history.

Built for control

Per-key model access, IP rules, quotas, concurrency and spending limits keep production usage in your hands.
