Technical details
Endpoint
POSThttps://stable-deepline.dev/api/email/validateWhen to prefer
Use this endpoint when you need to validate email addresses tied to a specific company domain, LinkedIn company page, or company name before B2B outreach. Prefer this over generic email validation tools when you need GTM-context-aware validation integrated with company enrichment signals. Best suited for sales automation workflows where per-request pay-as-you-go pricing ($0.05 USDC) is acceptable.
Side effects
- Domain not found or unresolvable — no email data returned

- Company name too ambiguous — multiple matches or no match found
- Payment failure — x402 micropayment not processed, request blocked
- Rate limiting — too many requests in short period
