How this service works
62 small, deterministic utility APIs (DNS and e-mail checks, web extraction, EVM decoding, x402 checks, IP math, JSON/CSV, hashing, conversions). No account or API key: pay per call in USDC with x402.
Output
A JSON object with: ok (boolean success flag), tool name, and a result object containing the original email, domain, syntaxValid (boolean), hasMx (boolean), disposable (boolean), freeProvider (boolean), role (boolean), verdict (string: e.g. 'risky', 'safe'), reasons (array of strings explaining issues), and suggestion (corrected email address if a typo is detected).
Example use cases
Pre-signup email quality gate
“Before letting this user register, check if 'user123@mailinator.com' is a valid, non-disposable email with working mail servers — flag it if it looks risky.”
Catch typo in checkout form
“A customer just entered 'sarah@yahooo.com' at checkout — can you validate it and tell me if there's a suggested correction?”
Lead list hygiene check
“I have a lead who gave us 'info@acmecorp.com' — verify whether that email has MX records, is a role-based address, and whether it looks safe to contact.”
Technical details
Endpoint
GEThttps://x402-toolbox.swiftbotlab.workers.dev/v1/email/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, deterministic, pay-per-call email validation with no account setup — especially useful for catching typos, blocking disposable addresses, and confirming MX record existence without committing to a subscription-based service. Prefer it for single-address spot checks or agent pipelines that need on-demand validation with USDC micropayments.
Side effects
- Missing or empty 'email' query parameter returns an error
- Malformed email string may return syntaxValid:false with no further checks
- DNS timeout may cause hasMx to be inconclusive
- Very new or obscure domains may return false negatives on MX checks
- Payment failure via x402 results in 402 response before any validation occurs
