Header formatlink

Public endpoints accept Authorization: Bearer YOUR_API_KEY and the Anthropic-standard x-api-key: YOUR_API_KEY. If both headers are sent, they must contain the same key.

# Anthropic SDKs and Claude Code
x-api-key: YOUR_API_KEY

Key safetylink

Do not ship keys in browser code, public repositories, client bundles, or logs.

Key managementlink

Use the API page to create, pause, rename, and delete keys, and to inspect usage records.

Hosted credentialslink

When hosted credentials are enabled, that key only uses your credentials and does not fall back to the public pool.
