Here's the updated README with the additional information on manual authentication using JSON payload:

# Suno API

This is the Suno API built with FastAPI. The API includes endpoints for generating music, fetching feeds, generating lyrics, and handling user credentials through sessions (cookies) or direct payload.

```json
{
  "data": {
    "cookie": "string",
    "session_id": "string"
  },
  "model": {
    "field": "value"
  }
}
```
