You’ll learn to run Claude Code (and Cursor, and the SDKs) on per-token API billing through UplinkSwitch, in four lessons: the two-variable setup, what a day of use actually costs with prompt caching worked through, how to keep the bill down, and the same key in Cursor and the OpenAI, Anthropic and Gemini SDKs.

Includes $10 of UplinkSwitch prepaid credit, on your balance as soon as the payment clears. After that you pay only for the tokens you use. Claude Sonnet 5.5 is $1.20 in and $3.00 out per million tokens here, against a $2 and $10 list price.

35 million tokens served since launch in October 2026. 81 models are tested every day, with the results public at uplinkswitch.com/proof.

Pay by card or crypto. At checkout, crypto is under “more payment methods”.
