How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the last 4 digits of the card number (`last4`) and a fully masked string (`masked`) where all digits except the last 4 are replaced with asterisks, plus a schema identifier `delx/util-card-mask/v1`.
Example use cases
Receipt display sanitization
“I need to show a customer their card on a receipt confirmation — can you mask the full number 5500005555555559 so it displays as asterisks with only the last 4 digits showing?”
Audit log card redaction
“Before I write this transaction to my audit log, mask the card number 4012888888881881 so we're not storing full card details.”
UI card display formatting
“I want to show the user which card they used for checkout — take the number 378282246310005 and give me the masked version like ************0005.”
