Once a session is open, you talk to the proxy-router exactly like you would talk to OpenAI: same routes, same body schemas. The only difference is the session_id header and the BasicAuth header for the local API.

​
Headers

HeaderRequiredPurpose
Authorization: Basic <base64(user:pass)>YesAuth to your local proxy-router. See API auth.
session_id: 0x...Yes (for remote)Which open Morpheus session to route through. Omit for the bundled local model.
Content-TypeAs neededapplication/json or multipart/form-data.

​
Chat completions

Streaming, OpenAI-compatible, model field is set by the provider based on session_id: 
curl -X POST 'http://localhost:8082/v1/chat/completions' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Basic YWRtaW46YWRtaW4=' \
  -H 'session_id: 0x8e12df2f764b416c0ea1936a253c2a4be01005651c2d73f22dd0d72520f93ca1' \
  -d '{
    "messages": [
      {"role": "system", "content": "You are a helpful assistant."},
      {"role": "user", "content": "Tell me about AI."}
    ],
    "stream": true
  }'
Streaming responses are SSE (text/event-stream); non-streaming returns application/json.

​
Audio transcriptions

POST /v1/audio/transcriptions — multipart form-data; the body is forwarded to the provider, so any field the provider accepts will pass through. Common fields: file, language, response_format, timestamp_granularities[], enable_diarization. 
curl -X POST 'http://localhost:8082/v1/audio/transcriptions' \
  -H 'Authorization: Basic YWRtaW46YWRtaW4=' \
  -H 'session_id: 0x...' \
  -F 'file=@harvard.wav'

​
Audio speech (TTS)

curl -X POST 'http://localhost:8082/v1/audio/speech' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Basic YWRtaW46YWRtaW4=' \
  -H 'session_id: 0x...' \
  -d '{"input": "Hello world.", "voice": "af_alloy"}'
Response is audio/mpeg (or whatever response_format you specified).

​
Embeddings

curl -X POST 'http://localhost:8082/v1/embeddings' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Basic YWRtaW46YWRtaW4=' \
  -H 'session_id: 0x...' \
  -d '{"input": "The quick brown fox jumped over the lazy dog", "encoding_format": "float"}'

​
Closing a session early

Always close manually if you are finished well before the session timer expires. Unused stake returns to your wallet on close. 
curl -X POST 'http://localhost:8082/blockchain/sessions/<sessionId>/close' \
  -H 'Authorization: Basic YWRtaW46YWRtaW4=' -d '{}'
