How this service works
Validate a value. Body: {type, value, schema?}. type = luhn (credit-card number), iban (bank account), email, or json_schema (validate value against a provided JSON Schema). Returns {valid, ...}.
Output
Returns a JSON object with a 'valid' boolean field indicating whether the supplied value passed the chosen validation. May include additional details depending on the type — for example, error reasons or parsed components of the value.
Example use cases
Credit card number format check
“Before I process this payment, can you run a Luhn check on card number 4916338506082832 to see if it's structurally valid?”
IBAN validation before wire transfer
“I need to send money to IBAN GB29NWBK60161331926819 — can you verify that's a properly formatted IBAN bank account number?”
JSON payload schema validation
“I have a JSON object {"name":"Alice","age":30} and I want to make sure it conforms to my schema requiring name as a string and age as an integer — can you validate it?”
Technical details
Endpoint
POSThttps://x402.shizu.me/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call validation service in an agent workflow without running local validation libraries. Especially useful for Luhn (credit card), IBAN, and email checks in financial or onboarding flows, or for validating arbitrary JSON payloads against a schema without spinning up a dedicated validator service. The x402 micropayment model makes it ideal for occasional, low-volume checks.
Side effects
- Missing 'type' or 'value' fields in request body returns a 400-level error
- Unsupported type value causes rejection
- For json_schema type, missing 'schema' field causes failure
- Malformed JSON body causes parse error
- Network timeouts on overloaded endpoint
