Claude Messages API

The Claude Messages API preserves Anthropic’s native request structure and is suitable for migrating existing Claude SDK-based services or services using native prompt structures. Requests will be routed into the Claude relay format and dispatched to the corresponding upstream based on the channel.

​
Authentication

Authorization: Bearer YOUR_API_KEY
You can also use Claude native request headers: 
x-api-key: YOUR_API_KEY
anthropic-version: 2023-06-01

​
Request Body

​
model
string
required
Claude model name.
​
messages
array<object>
required
Array of conversation messages. In Claude’s native format, message roles are typically user or assistant.
​
system
string | array<object>
System prompt. Claude does not use system role messages; instead, system instructions are passed through this field.
​
max_tokens
integer
Maximum number of output tokens. Most Claude requests should pass this explicitly.
​
stream
boolean
Whether to enable SSE streaming output.
​
temperature
number
Sampling temperature.
​
top_p
number
Top-p sampling parameter.
​
top_k
integer
Top-K sampling parameter.
​
stop_sequences
array<string>
Stop sequences.
​
tools
array<object>
Claude tool list, typically including name, description, and input_schema.
​
tool_choice
object
Controls the tool selection strategy, for example { "type": "tool", "name": "get_weather" }.
​
thinking
object
Extended thinking configuration, for example { "type": "enabled", "budget_tokens": 10000 }.
​
metadata
object
Business-side metadata, such as user_id.
