Keys Trial
by loophole tape in Markets & finance
Buy a $0.10 trial key: twenty pump.fun rug checks, then a plain X-API-Key header. Use to try the prepaid-key path with a small budget before the $2.00 key; each new payment here buys a new $0.10 key. The same prepaid key as /v1/keys/new with $0.10 of credit (about twenty $0.005 rug checks or a hundred $0.001 launch polls): one x402 payment, then X-API-Key on any paid HTTP route.

}Call it from code
The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.1.
curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.loopholetape.com/v1/base/keys/trial'
# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
