For bulk, some NSS checker API providers offer a batch endpoint taking an array of NSS numbers. Otherwise, parallel async requests with a semaphore to stay within rate limits works fine for 500 records.

I'm looking for an NSS checker API that can quickly validate whether a given NSS is structurally valid (passes the Luhn check) and also verify it exists in IMSS. We run batch imports of employee data and need to catch bad NSS values before they cause payroll issues.
Does any NSS checker API support bulk validation? We might have 500+ records to check on initial import. What rate limits should I expect?
