SDKs & agents

Anthropic SDK

Use the official Anthropic SDK unchanged. Set the base URL to the Gateway (no /v1 — the SDK appends /v1/messages itself), pass a project API key, and call any model returned by GET /v1/models.

Setting	Value
Base URL	`https://api.atptoken.ai`
Auth	`Authorization: Bearer atp-…` (SDK default)
Model	any id from GET /v1/models

from anthropic import Anthropic

client = Anthropic(base_url="https://api.atptoken.ai", api_key="atp-...")
msg = client.messages.create(
    model="<model from GET /v1/models>",
    max_tokens=256,
    messages=[{"role": "user", "content": "hi"}],
)
print(msg.content[0].text)

Set stream=True for SSE streaming — see Anthropic SSE. Note the top-level system field must be a string; the array form is not yet supported. Full endpoint reference: /v1/messages.
