How it works
3 steps. Seconds.
1

Pay crypto

Send USDT / BTC / ETH for the plan you picked.

2

Get your key

We mint a fresh, isolated key funded to 2× your payment.

3

Use it anywhere

Plug base_url + api_key into any SDK, Cursor, or Claude Code.

Your key is capped & locked — by design

HARD CAP — can't overspend MODEL LOCK — catalog only LIVE METER — cx.tpkcur.click IP BIND — optional

Watch the balance anytime at cx.tpkcur.click. When it runs low, top up. Never pay for more than you use. Full detail on the How it works page.

What builders say
Real users. Real doubles.
"Switched my whole agent stack to Dopp. Same Claude Opus 4, literally half my bill. The key capped itself exactly where I funded it — zero surprise."
@neon_runner · indie dev
"I was burning $400/mo on GPT-5.5 Pro. On Dopp that's $200 and I got the same tokens. Set it up in 2 minutes with the base_url."
@cipher_ko · ML engineer
"The 2× isn't marketing fluff. I counted: $5 gave me 14M Fable tokens vs ~7M on the official API. Staying."
