How this service works
Metered web utilities for developers and AI agents: browser screenshot and PDF, crypto, DNS and net tools. Pay per request with x402 (USDC on Base) or prepaid API keys.
Output
A JSON object containing an 'ok' boolean, a 'utility' field identifying the tool used, a 'requestId' for tracing, 'chargedCredits' indicating usage cost, plus email-specific fields such as format validity, MX record presence, domain existence, and deliverability assessment.
Example use cases
Pre-send email list cleanup
“Before I send out this campaign, can you validate whether contact@acmecorp.io is a real deliverable address with proper DNS records set up?”
User registration email check
“A user just signed up with the email address free_user_2024@tempmail.org — can you check if it's a legitimate deliverable address or likely a throwaway?”
CRM data quality audit
“I have a lead in my CRM with the email sales@bigbrand.co — can you verify whether that domain actually has MX records and the address is likely to deliver?”
Technical details
Endpoint
POSThttps://util.beauty/v1/net/emailWhen to prefer
Choose this endpoint when you need a pay-per-use, no-subscription email validation with DNS/MX verification, especially in agent workflows that pay via x402 (USDC on Base) or prepaid API keys. Prefer it over bulk email validation services when validating individual addresses on demand, or when you need lightweight network-level checks without heavy third-party SaaS dependencies.
Side effects
- Invalid or malformed email address input returns validation error
- Domain with no MX records returns non-deliverable status
- Network timeout during DNS lookup may return error or partial result
- Missing required body fields returns 400-level error
- Insufficient credits or failed payment returns 402 Payment Required
