Technical details
Endpoint
POSThttps://x402.orthogonal.com/icypeas/api/email-verificationWhen to prefer
Use this endpoint when you need to verify a single email address for deliverability before sending outreach, adding to a CRM, or enriching a contact record. Prefer this over bulk solutions when validating individual contacts in real time. Pair with the Fetch Search Result endpoint to retrieve the final verdict after submitting.
Side effects
- Invalid email format — malformed address rejected before lookup
- Non-existent domain — domain cannot be resolved
- Search ID returned but polling yields no result if verification times out
- Payment failure — 402 if USDC payment not provided
- Rate limiting or quota exceeded
