Schwab requires an HTTPS callback. The usual answer is https://127.0.0.1:8182 behind a self-signed certificate, which means clicking through a browser warning on every re-authentication — and the refresh token expires weekly. There are also reports of Schwab refusing to register apps whose callback is a loopback address. This app already terminates real HTTPS, so it can take the redirect itself. Unauthenticated by necessity: the provider redirects a browser here and cannot attach the chart token, so it sits alongside /health and /version. It is inert — nothing is stored, and the page echoes only the query string of the request that produced it, which the caller already has in their address bar. Retaining the code would let a later anonymous visitor read it. The path and the page are both deliberately unrevealing. That is not a security control; it just avoids advertising which brokerage this host talks to. Treat the path as fixed — changing a registered callback means editing the app, which can send it back through approval. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
