How this service works
Pay-per-call data and tools for AI agents, $0.002-0.01 per call in USDC via x402 (Base, Polygon or Solana), no account or API key; MAX tiers ($0.05-0.25) run deeper jobs. Agent toolkit: web search, search + read top pages, any page as clean markdown with a prompt-injection check, which-x402-API-to-call recommender, seller check. Data: Google Maps places with contacts, YouTube video data and transcripts, job listings (Indeed, LinkedIn, 13 boards), Google Ads Transparency, TikTok comments, Pinterest, Airbnb, Redfin, AliExpress, app stores, live sports, website and SEO checks, Shopify store tech stacks, and onchain token / address risk checks.
Output
Returns per-address results including: a verdict (valid, risky, or invalid), a confidence score, the detected mailbox provider (e.g. Google, Microsoft, Zoho), flags for disposable/temporary domain, free webmail, and role account, plus a typo suggestion if the domain looks misspelled. No SMTP probing is performed and no email is sent.
Example use cases
Lead list hygiene before campaign
“I have a batch of emails collected from our sign-up form — can you check these 15 addresses and tell me which ones are valid, which are risky or disposable, and flag any obvious typos before I import them into our CRM?”
Catching fake sign-ups in real time
“Someone just registered with burner@mailinator.com — can you verify that email and tell me if it's a temporary or disposable address so I can decide whether to block the account?”
Identifying role accounts in B2B outreach
“Before we send our outreach emails, can you validate these addresses and let me know which ones are role-based like info@ or support@ versus actual personal inboxes, and whether any have typos in the domain?”

Endpoint
GEThttps://agent-data.centorprat.workers.dev/email/verify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, privacy-safe email validation without SMTP probing or sending any mail — ideal for pre-send list hygiene, sign-up validation, or CRM enrichment workflows. It handles up to 20 addresses per call with ~1s latency, covers disposable domain detection (~10k known domains), typo correction, and mailbox provider identification, making it suitable for both single-address real-time checks and small-batch lead list processing.
Side effects
- More than 20 email addresses submitted in one call — request rejected or truncated
- Malformed email input string — validation error returned
- Network timeout or worker error — HTTP 5xx response
- Invalid query parameter format — missing or empty 'email' param returns error
- Unknown or very new domain — MX lookup may be inconclusive, result marked risky
