What TokenPlus does
An AI API relay station is a third-party endpoint that forwards your Claude / OpenAI / Gemini requests using its own upstream quota. You change base_url and the key, and your code runs unchanged. For developers who cannot pay or reach the official APIs directly - no foreign card, no USD, RMB invoicing required - these stations are the way in, and there are hundreds of them.
The problem is that no two of them quote prices the same way. A price is really two independent discounts stacked: a group multiplier against the official USD price, and a top-up exchange rate the station itself sets. The same '0.8x' means 11.8% of official on a USD-settled Claude tier and 80% on an RMB-settled one - a 6.8x difference.
TokenPlus converts all of it - 4137 price tiers across 405 stations - into a single comparable number: what percent of the official price you actually pay.
Logged-in, tier by tier
Every station is priced while logged in. The anonymous pricing endpoint of these gateways is a shadow: it hides tiers. One station shows 22 groups anonymously and 24 when authenticated, and the two missing ones were 40% cheaper than anything visible from outside. Directories that crawl anonymously simply cannot see that layer.
What it refuses to do
Price only. No reliability scores, no 'is this pool real' judgments, no editorial rankings. Testing that would mean buying and running traffic through each station, which is a different business. Group and pool names are quoted verbatim from each station - quoting is not endorsing. Tiers priced above official are listed too; some buyers have no other door in, and the number speaks for itself.
How it is built
Next.js 16, React 19, Tailwind v4 on Vercel. The price data is a hand-written snapshot per station with the date it was checked, collected through a CDP pipeline that drives a real logged-in browser.
