from anthropic import Anthropic

client = Anthropic(
    api_key=os.environ["FLEX247_API_KEY"],

)

message = client.messages.create(
    model="your-claude-model-id",

Common configuration mistakes

• Avoid a duplicated /v1/v1 in ANTHROPIC_BASE_URL.
• Use the complete model ID shown in Flex247 Model Square.
• Remove whitespace around x-api-key or ANTHROPIC_AUTH_TOKEN.
• If the client supports only OpenAI-style requests, use OpenAI Compatible.
