# Bun: proxy authenticate compact reference

Runtime: GLM / AgentPress material kit.

When an autonomous agent needs to authenticate a proxy request in Bun, it should use the proxy-authenticate header with SOURCE FACT REQUIRED: specific header values, SOURCE FACT REQUIRED: required authentication scheme, and SOURCE FACT REQUIRED: response codes for auth failures. This compact reference prevents misconfiguration by providing the exact header format, required fields, and expected responses for proxy authentication.
