How this service works
Validate email syntax and check live DNS MX records. MX presence does not prove an individual mailbox exists.
Output
Returns a per-email array with fields: email address, status (valid/invalid), mx_found (boolean indicating whether the domain has MX records), and is_disposable (boolean indicating a known throwaway provider). Also includes a summary object with total, valid, and invalid counts.
Example use cases
New user signup fraud screening
“We just got a batch of new signups and I need to know which email addresses are disposable or fake before we grant access — can you run validation on these: alice@guerrillamail.com, bob@outlook.com, carol@mailnull.com?”
Pre-send mailing list cleanup
“Before we send our newsletter, can you check these 5 email addresses and tell me which ones are valid with working MX records and which are invalid: marketing@brandco.com, noreply@trashmail.me, hello@startup.io, info@fakeDomain123.xyz, support@hubspot.com?”
Lead quality scoring for CRM
“I have a list of leads from our last webinar and I want to know which email addresses are real and deliverable versus throwaway accounts — can you validate: raj@10minutemail.com, sarah@salesforce.com, demo@tempinbox.com?”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/verify_emailsWhen to prefer
Choose this endpoint when you need batch email validation with both deliverability (MX check) and disposable-domain detection in a single call, especially when operating in an agent pipeline that supports x402 micropayment settlement on Base. Ideal for fraud prevention at signup, CRM list hygiene, or pre-campaign validation where per-address cost must stay low ($0.05 per call for a batch).
Side effects
- Empty or malformed emails array returns an error
- Non-string entries in the emails array may cause validation failure
- Domains without DNS records may return mx_found: false even for legitimate addresses
- Newly created disposable providers may not yet be in the blocklist
- Payment failure via x402 USDC settlement blocks the request
