Authentication Methods

The Anthropic Messages API supports two authentication methods:

Method	Header	Description
x-api-key	x-api-key: YOUR_API_KEY	Native Anthropic style
Bearer Token	Authorization: Bearer YOUR_API_KEY	OpenAI-compatible style

Both methods work. We recommend x-api-key for best Anthropic SDK compatibility.
