# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://api.xona-agent.com/base-main/image/flux-2-pro" \
-H 'content-type: application/json' \
-d '{"aspect_ratio": "1:1", "prompt": "", "referenceImage": []}'
# 2) Paying + retrying requires an x402 client that can sign the USDC
# authorization (curl alone cannot). See the JS / Python tabs below.
