Overview
One OpenAI Responses-compatible API for all models across providers.
Ramp Router puts one OpenAI Responses-compatible endpoint in front of models from multiple providers. Your application holds a single Router key; Router holds the provider credentials and never asks you to send them.
API surface
| Method | Route | Purpose |
|---|---|---|
GET | /v1/models | List the models available to the current key |
POST | /v1/responses | Create a buffered or streaming model response |
Each request sends exactly one of model (a model ID) or models (an ordered
fallback list).
Start with the quickstart, or go straight to connecting your app if you already call the Responses API.
