Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://perp-gap-api.perpgap.workers.dev/history?from=2026-10-07T00%3A00%3A00Z&interval=1h&ticker=TSLA&to=2026-10-14T00%3A00%3A00Z'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://perp-gap-api.perpgap.workers.dev/history?from=2026-10-07T00%3A00%3A00Z&interval=1h&ticker=TSLA&to=2026-10-14T00%3A00%3A00Z' \
