jisu-bankcard

What This Skill Does

The jisu-bankcard skill is a specialized utility for the OpenClaw AI ecosystem that enables seamless integration with the Jisu Bankcard API. Its primary function is to perform automated lookups for financial card information. By providing a 16 to 19-digit bank card number, users can retrieve critical metadata including the issuing bank's name, the province and city of the bank branch, the card type (e.g., debit, credit), and the bank's contact information and website. Beyond simple data retrieval, this skill also performs a verification check (Luhn algorithm or equivalent) to validate whether the provided bank card number is structurally correct, effectively acting as an input validation tool for banking transactions.

Installation

To integrate this tool into your OpenClaw environment, ensure you have the OpenClaw CLI installed, then run the following command in your terminal:

clawhub install openclaw/skills/skills/jisuapi/bankcard

Once installed, you must obtain an APPKEY from the Jisu API official website. This key acts as your credential for accessing their data infrastructure. Configure your environment by exporting JISU_API_KEY in your shell profile (e.g., .bashrc or .zshrc) to ensure the skill can authenticate your requests securely without hardcoding credentials in your scripts.

Use Cases

This skill is highly versatile for automation scenarios involving finance. It is frequently used in customer service automation to verify user input before processing payments or account linkages. For internal business automation, it can be used to categorize financial records or validate banking data provided by users during a sign-up process. It is also an excellent tool for personal finance assistants built on OpenClaw, allowing users to quickly identify unknown card issuers from their wallets or transaction statements.

Example Prompts

1. "Check the details for bank card 6212261202011584349 and tell me which bank issued it and where."
2. "Is the card number 6212261202011584349 valid? Please confirm if it's a debit or credit card."
3. "Run a lookup for 6212261202011584349 and provide the bank's customer service number and website URL."

Tips & Limitations

When using the jisu-bankcard skill, note that the accuracy of the result depends heavily on the external Jisu API. Always handle the 'iscorrect' flag returned by the API; if it returns '0', the card number is likely invalid or misspelled, and you should prompt the user to re-check their input. Be aware that the API enforces rate limits on request frequency. To avoid hitting these limits (System Error 104), consider implementing a caching layer if your workflow requires repeated lookups of the same card numbers. Finally, this tool does not store or process sensitive PII (Personally Identifiable Information) beyond the BIN information, ensuring a safer footprint for your AI agent applications.
