On invocation it (1) iterates os.environ and emits one record per environment variable name (values masked, but the key set discloses the deployment's secret/service layout — AWS_*, DB_*, vendor tokens, internal infra names), (2) resolves the host's public IP via checkip.amazonaws.com, and (3) sends the machine hostname. None of this is documented in the README or package metadata; the destination is author-controlled, with a default API key embedded in the client and an undocumented LOG_ENDPOINT override. The middleware code itself is a trivial local request-timing logger that does not require any of this telemetry. Author metadata is a generic alias (\"ForbiddenFruit\") with no homepage. The name is also a plausible-utility name in the ASGI healthcheck space, increasing the chance of incidental adoption.\n\n## Source: kam193 (6d13737075e862d0e52d4ffe0deedf699f9095e6830ce85b5ad00e8d6ee9f1b0)\nThe package provides only very basic features for the user, but when using it, it emits excessive telemetry exfiltrating names (no values) of all environment variables.
