How this service works
86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.
Output
Returns a JSON object with the original email, a breakdown of validation checks (format_valid, domain_has_mx, is_disposable, is_role_address), the domain, local part, list of MX records, and an overall is_valid boolean.
Example use cases
Pre-send email verification
“Before I send this campaign, can you validate 'newsletter-signup@tempmail.org' and tell me whether it's a disposable address or actually deliverable?”
Signup form fraud filtering
“A new user just registered with 'admin@fakeburner.xyz' — can you check if that email is valid, has real MX records, and isn't a role or throwaway address so I can decide whether to approve their account?”
CRM contact list hygiene
“I'm cleaning up my contact list — can you validate 'sales@bigcompany.com' and tell me whether it's a role address, whether the domain has MX records, and whether the overall email looks legit?”
Technical details
Endpoint
POSThttps://agentsvc.io/api/v1/proxy/email-validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, per-call email validation without setting up an account or API key, and want to pay only $0.002 USDC per check via x402 on Base. It is ideal for agents that need to validate individual emails on-demand — e.g. at signup, before outreach, or during list hygiene — and need both syntax and deliverability signals including MX records and disposable-address detection.
Side effects
- Invalid or malformed email format provided — API may return format_valid: false or an error
- Domain does not exist or has no MX records — is_valid will be false with domain_has_mx: false
- Network timeout when performing MX lookup for obscure domains
- Empty or missing email field in request body — likely returns a validation error
