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.
