Authorization
string
필수
All endpoints require Bearer Token authenticationGet your API Key from the API Key Management PageAdd to request header:
Authorization: Bearer YOUR_API_KEY

​
Body

​
model
string
기본값:"gpt-5.5"
필수
모델 nameExample: "gpt-5.5"
​
messages
object[]
필수
List of conversation messages in chronological order
​
stream
boolean
기본값:false
Whether to enable streaming output (Server-Sent Events)
  • true: Stream tokens incrementally
  • false: Return the complete response at once
​
max_tokens
integer
Maximum number of tokens to generateUses the model’s default limit when not set
​
temperature
number
기본값:1
Sampling temperature, controls output randomness
  • Range: 0 to 2
  • Lower values produce more deterministic output; higher values produce more varied output
​
top_p
number
기본값:1
Nucleus sampling probability thresholdRange: 0 to 1. It is not recommended to modify both temperature and top_p at the same time
​
stop
string | string[]
Stop sequences — generation stops when these strings are encounteredMaximum 4 stop sequences
