One OpenAI-compatible API across image, video, chat, music and code models
Reach image, video, chat, music and code models from many vendors through a single API key and an OpenAI-compatible request shape, so existing client code keeps working.
reAPI handles vendor selection and re-routes requests to a redundant provider when one degrades, which the company positions as sub-second failover behind a 99.96% uptime claim.
The platform states that your requests and responses are never stored on its side, which matters for teams with data-handling obligations.
Billing runs on prepaid credits worth $0.001 each, with per-key spend caps, team budget controls and automatic refunds for failed generations.
