Call it from code

The curl command shows the payment challenge.

# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://fittings.sh/v1/crypto/random-bytes?bytes=32&encoding=hex'

# 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://fittings.sh/v1/crypto/random-bytes?bytes=32&encoding=hex' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode

We don't show code that pays this service: it uses a payment scheme other than exact, which needs a different client setup.
