# -i = print status line + response headers (required to see 402 + PAYMENT-REQUIRED)

# Expect: HTTP/2 402 and header PAYMENT-REQUIRED: <base64…>
# JSON body is often {} — the priced offer is in that header (x402 v2).
# Decode: copy the header value, then: echo '<paste>' | base64 -d | jq .

# After you have a payment proof, retry with PAYMENT-SIGNATURE (what @x402/fetch sends).
