How this service works
Pay-per-call data services for AI agents: web extraction (text, Markdown, metadata), PDF-to-text, RSS/Atom parsing, FX and crypto prices, weather, DNS and email validation. All paid endpoints use the x402 payment protocol (USDC).
Output
Returns a validation result for the provided email address, typically including format validity, domain existence, MX record check, and an overall deliverability assessment (e.g. valid, invalid, risky, or disposable).
Example use cases
Pre-send email list cleanup
“Before I blast this newsletter campaign, validate these email addresses and flag any that look invalid or undeliverable — start with newsletter@acme-corp.io.”
User registration form validation
“A new user just signed up with the email address user123@tempmail.xyz — can you check if it's a real, deliverable address or a disposable/fake one?”
CRM data hygiene check
“I'm cleaning up our CRM and I want to know if the email address on file for our client — sarah.johnson@bigclient.com — is still valid and deliverable.”
Technical details
Endpoint
GEThttps://agent-data-api-ui1c.onrender.com/net/emailWhen to prefer
Choose this endpoint when you need a quick, pay-per-call email validation check without a subscription commitment, especially inside an AI agent workflow that already handles x402 USDC micropayments. It's ideal for spot-checking individual email addresses at low cost ($0.005 per call) rather than bulk validation via a dedicated email hygiene platform.
Side effects
- Missing 'address' query parameter returns a 400 Bad Request
- Malformed email string may return an invalid format error
- Payment failure via x402 protocol returns a 402 Payment Required response
- Unresolvable domain may return a domain-not-found error
- Network timeout on DNS lookup may cause a 503 or timeout error
