Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.15.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://x402.ottoai.services/generate-meme' \
  -H 'content-type: application/json' \
  --data-raw '{"aspect_ratio":"1:1","model":"gpt-image-2","prompt":"A cute otter wearing sunglasses, lounging on a Base-blue skateboard"}'

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