How this service works
x402-powered API services for AI agents
Output
A JSON object containing a summary with the total number of emails submitted, the count of valid addresses, and the count of invalid addresses.
Example use cases
Pre-send mailing list cleanup
“I have a list of 75 email addresses I collected from our sign-up form — can you run them all through bulk validation and tell me how many are good and how many I should drop before I send the campaign?”
CRM data quality audit
“We just exported 90 contacts from our CRM and I want to know which email addresses are invalid so we can flag them — please validate the whole batch at once.”
Lead list verification before outreach
“Here are 60 email addresses from a lead generation file — validate them in bulk and give me a count of valid versus invalid ones before our sales team starts outreach.”
Technical details
Endpoint
POSThttps://mach402.dev/validate/email/bulk?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate more than one email address at a time and want a single aggregated summary. It is more cost-efficient than calling a single-email endpoint repeatedly. Choose this over single-address validation when cleaning mailing lists, auditing CRM exports, or scrubbing lead files in one shot. The optional SMTP probe is available but defaults to off for bulk, making it faster for pure format and domain-level checks.
Side effects
- Input list exceeds 100 emails — request rejected
- Malformed email entries in array — may cause individual items to be flagged invalid
- Empty emails array — likely returns error or zero-count summary
- Invalid JSON body — 400 or similar error
- Payment failure via x402 — 402 response, call not processed
