reverse-proxy-api keeps one base_url and one key in front of 300+ models — USD settlement, pay-as-you-go, $1 minimum top-up.
reverse-proxy-api indexes reverse-engineered and official routes side by side: the -ext IDs are the reverse-engineered upstream label, every other model is routed officially at a discounted unit price. One key covers both.
