Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

# bash or zsh: see the payment challenge. Nothing is charged.

# To read the header:
curl -sS -g -o /dev/null -D - 'https://api.sitecheck-api.workers.dev/api/solana/quote?amount=1&from=SOL&to=USDC' \
