How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The upstream response body and content type are passed through after successful x402 payment validation. Typically confirms whether the email was dispatched or returns a status from the underlying email provider.
Example use cases
Agent-triggered transactional email
“Send a transactional email notification with the body 'Your order #4821 has shipped and will arrive by Friday' using the abstract-email service, paying per send.”
DeFi workflow email alert
“After my on-chain transaction confirms, fire off an email alert with body 'Your DeFi vault rebalance is complete — new allocation: 60% ETH, 40% USDC' via the x402 email gateway.”
Micropayment-gated bulk notification
“Send an email with the message 'Your staking rewards have been distributed — log in to claim' through the abstract-email endpoint, paying the $0.01 USDC fee per call.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/abstract-email?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent or web3 application needs to send email as part of an automated workflow and requires pay-per-use micropayment billing via the x402 protocol with USDC, rather than maintaining a subscription-based email service account.
Side effects
- Payment insufficient or x402 payment header missing — returns 402 Payment Required
- Invalid or missing body field — upstream may reject malformed email payload
- Path misconfigured — upstream origin not reachable, returns 502 or 404
- Rate limiting by upstream email provider
- Malformed query object causes routing failure
