Anthropic SDK Integration

This site speaks the Anthropic Messages protocol: point the official SDK’s base_url at https://api.aiwanai.cc and call Claude models directly.

Python

pip install anthropic

import anthropic

client = anthropic. Anthropic(
    api_key="sk-your-api-key",
    base_url="https://api.aiwanai.cc",
)

message = client.messages.create(
    model="claude-sonnet-4-5-20250929",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Say hello in one sentence"}],
)
print(message.content[0].text)

JavaScript / TypeScript

npm install @anthropic-ai/sdk

import Anthropic from '@anthropic-ai/sdk'

const client = new Anthropic({
  apiKey: 'sk-your-api-key',
  baseURL: 'https://api.aiwanai.cc',
})

const message = await client.messages.create({
  model: 'claude-sonnet-4-5-20250929',
  max_tokens: 1024,
  messages: [{ role: 'user', content: 'Say hello in one sentence' }],
})
console.log(message.content)

Key points

base_url is the site root https://api.aiwanai.cc (the SDK appends /v1/messages itself) — no/v1 suffix

Both the SDK’s default x-api-key header and Authorization: Bearer work

max_tokens is required by the Anthropic protocol

Claude models are also reachable via the OpenAI-compatible endpoint — pick either

Model names come from the Pricing page; for errors see Error codes & troubleshooting
