Endpoint

Choose this endpoint when you need to batch-classify up to 500 email addresses as international or local in a single paid API call. It is well suited for CRM enrichment, marketing segmentation, or compliance auditing workflows where geographic email classification is needed at scale and per-call micropayment pricing (USDC on Base) is acceptable.
Side effects
- Empty emails array returns validation error
- Emails array exceeding 500 items rejected
- Malformed email strings may return error or be flagged invalid
- Payment failure via x402 protocol blocks request
- Network timeout for large batches near the 500-item limit
