# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/url/clean?url=https%3A%2F%2Fexample.com&format=markdown'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/url/clean?url=https%3A%2F%2Fexample.com&format=markdown' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):

#     --experimental-strip-types scripts/x402-pay.ts \
#     'https://2s.io/api/url/clean?url=https%3A%2F%2Fexample.com&format=markdown'
