Performance Evaluation We simulated WebGPI downloads over 4G (10 Mbps, 50 ms RTT) and satellite (2 Mbps, 600 ms RTT) links.

If you provide the of your WebGPI (e.g., a GitHub link, internal API docs, or intended use case), I can tailor the paper with exact endpoint schemas, code examples, and security profiles. Implementation Guide (Pseudo-API) 5

All WebGPI download endpoints must enforce HTTPS and return X-Content-Type-Options: nosniff . 5.
