Example use cases
Pre-send email validation for outreach
“Before I launch this cold email campaign, can you check if alex.turner@acmecorp.com is a valid, deliverable address so I don't waste a send on a bounce?”
New user signup email check
“A user just signed up with the email sarah.jones@freemail.biz — can you quickly verify that it's a real address and not a throwaway or fake one?”
CRM lead email quality screening
“I have a lead in my CRM with the contact email derek.mason@startupxyz.io — can you verify it's legitimate before my sales rep reaches out?”
Technical details
Endpoint
GEThttps://whale-momentum.agentdiet.dev/v1/email-verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email verification check without committing to a bulk subscription service. It is well-suited for agents verifying individual email addresses at point-of-use, such as during lead enrichment, CRM updates, or pre-send validation flows. The $0.005 USDC micropayment model via x402 makes it cost-effective for sporadic or low-volume verification needs.
Side effects
- Missing or malformed email query parameter returns an error
- Unresolvable domain may result in inconclusive or failed verification
- Temporary DNS timeouts may cause lookup failures
- Payment required (HTTP 402) if USDC micropayment not attached
- Rate limiting if too many requests sent in quick succession
