Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.015.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.agentstools.dev/prediction/trades?limit=25&market=0xacec7e5b90ccb1ac4c950e3aff18156d6ce1bb7b0c87c001a281279412dca784'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
