Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.005.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://flat-rate-llm.kikoribera03.workers.dev/v1/evm/receipt?chain=base&hash=0x17f99c8d27a22958999b883d27e8a74b23bad5579832b269faf20ab884884ff3'

# 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://flat-rate-llm.kikoribera03.workers.dev/v1/evm/receipt?chain=base&hash=0x17f99c8d27a22958999b883d27e8a74b23bad5579832b269faf20ab884884ff3' \
