Native Orbit API - Orbit

The native chat route is useful for simple HTTP clients. For most apps, prefer the OpenAI or Anthropic SDKs.

Chat

POST https://api.tryorbit.cloud/api/v1/models/{slug}/chat
Authorization: Bearer $ORBIT_API_KEY

{slug} can be a catalogue slug (claude-sonnet-5) or the catalogue UUID.

curl https://api.tryorbit.cloud/api/v1/models/claude-sonnet-5/chat \
  -H "Authorization: Bearer $ORBIT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "messages": [{ "role": "user", "content": "Hello!" }],
    "stream": false
  }'
