How do I get an App ID?

You must register a developer account on the UnionPay International Developer portal. Once your business is verified, you can create an app to obtain credentials.

Does KYC card checking cost money?

Yes, depending on your contract with UnionPay, calls to identity verification and risk assessment endpoints may incur minor micro-transaction fees per successful hit.

Can I use RSA Certificates instead of App Secret?

This MCP wrapper abstracts away the complex RSA `.pfx` certificate signing by requiring standard API Key interaction, which is securely transformed in the agent execution runtime.
