Technical details
Endpoint
GEThttps://app.cusethejuice.com/api/bots/email-open-relayWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use SMTP relay without managing your own mail server infrastructure, especially in agentic workflows where email sending is an occasional action billed via x402 USDC micropayments on Base.
Side effects
- Invalid or malformed email address causes recipient to appear in 'rejected' array
- Payment failure via x402 results in 402 response before email is sent
- Missing required fields (from, to, subject, body) returns a 400-level error
- SMTP relay rejection due to spam filtering or domain reputation issues
- Network timeout during relay causes delivery failure
