Reverse Proxy Design for AI APIs
· 9 min read
An autonomous agent wants to update a customer record. Its HTTP request looks ordinary:
PATCH /v1/customers/42
Content-Type: application/json
{"creditLimit": 50000}
A conventional reverse proxy can terminate TLS, authenticate the caller, apply a rate limit, select an upstream, and forward the request. Those are essential controls. But the proxy still faces an agent-specific question: is this request a routine update, an unauthorized financial change, a confused tool call, or an action that should wait for human approval?
