Get Connection Proxy Info

Returns the proxy contract for a connection. Use this endpoint before calling [`POST /api/connections/{id}/proxy`](../../../../../api-reference/connections/execute-proxy) when you need to build requests programmatically. The response shows: - the inherited base URL that all proxied requests are sent to - locked headers and query parameters that are attached automatically - blocked request and response headers - allowed HTTP methods and body shapes - timeout, rate-limit, and payload-size limits Sensitive inherited header and query values are redacted in the response. The contract is still useful for discovering which keys are fixed by the connection, even though their raw values are not exposed.
