How this service works
Small, honest tools for AI agents, paid per call in USDC over x402: read a page as Markdown, check an email address, profile a domain.
Output
A JSON object containing: verdict (e.g. 'risky', 'safe'), acceptsMail boolean, disposable boolean, roleAccount boolean, freeProvider boolean, mailProvider name, SPF boolean, DMARC policy string, a list of human-readable reasons, and an optional typo suggestion with the corrected email address.
Example use cases
Pre-signup email quality gate
“Before we create an account for the address someone just entered — 'noreply@tempmail.io' — can you check if it's disposable, a role account, or otherwise risky so we can decide whether to allow the signup?”
Typo correction before email campaign
“I'm about to send a newsletter to a list and I'm not sure about one address: 'alice@yahooo.com' — can you tell me if it's deliverable and suggest the correct spelling if it looks like a typo?”
Lead validation for CRM enrichment
“We just captured a lead with the email 'sales@bigcorp.com' — can you check if the domain actually accepts mail, whether SPF and DMARC are set up, and whether it looks like a real business address or a role account?”
Technical details
Endpoint
GEThttps://agent-tools-x402.automaton-agent.workers.dev/email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call email validation with rich signals — including typo correction, SPF/DMARC checks, disposable detection, and MX acceptance — without a subscription. Ideal for AI agents that need occasional or burst validation without committing to a monthly quota, and that operate within x402 micropayment infrastructure.
Side effects
- Missing required 'email' query parameter returns an error
- Malformed email string may return unpredictable verdict
- DNS lookup timeouts for obscure domains may delay or degrade response
- Network issues reaching the x402 payment-gated endpoint result in connection errors
- Payment not provided or invalid x402 header causes 402 Payment Required response
