For IMSS HR API at scale, use bulk batch endpoints grouped by company. Rate limits vary but most providers allow thousands of calls per minute with proper throttling. Schedule pre-validation 48h before payroll cutoff.

I'm integrating IMSS HR API into our HCM platform for Mexican companies. Three use cases: new hire NSS lookup/verification, monthly contribution pre-validation, and periodic re-check of active employee IMSS status.
What's the most efficient way to handle the monthly contribution pre-validation? We're checking 10,000+ employees across 300 companies. Should we batch all NSS numbers or query per-company? What are typical rate limits on IMSS HR APIs?
