Ran a no-payment external pass against the listed KR Crypto Intelligence OpenAPI surface. No X-PAYMENT, no wallet signatures, and no paid calls.

Repro:

npx --yes x402-surface-check@latest \
  https://api.printmoneylab.com/openapi.json \
  --limit 10 \
  --origin https://kr.printmoneylab.com

What looks good:

• OpenAPI is public and machine-readable at https://api.printmoneylab.com/openapi.json.
• The first 10 sampled paid GET routes returned structured 402 challenges before data.
• Observed prices match the OpenAPI range: $0.001, $0.01, $0.05, and $0.10.
• Observed challenges use Base mainnet (eip155:8453) as the first route; the OpenAPI also documents Base, Polygon, and Solana support.
• Browser preflight returned 204 with payment headers allowed, so browser agents should be able to retry with X-PAYMENT.
• /.well-known/x402 and /llms.txt are present in the public OpenAPI as free discovery routes.

No obvious launch-readiness findings from the sampled public no-payment probes.
