How this service works
Disposable email inboxes for agents — create, receive, read, and send. Pay per call.
Output
Returns a message_id confirming the send, an accepted_at ISO timestamp, and a skipped array listing any recipients who were dropped because they previously unsubscribed from this inbox.
Example use cases
Example prompt
“Send an email from my disposable PayWeave inbox 'agent-notify-42' to hello@example.com with subject 'Your order is ready' and a plain-text body saying 'Hi there, your order has been processed and will ship tomorrow.'”
Technical details
Endpoint
POSThttps://mail.payweave.services/inboxes/%7Bslug%7D/sendWhen to prefer
Choose this endpoint when an AI agent needs to send outbound email from a disposable, agent-owned inbox without managing a full email service provider. Ideal for pay-per-use agent workflows where each email call costs $0.002 USDC and no monthly subscription is needed. Best when the agent has already created a PayWeave Mail inbox (identified by slug) and wants to send HTML or plain-text email with optional CC/BCC/reply-to fields.
Side effects
- Invalid or unknown inbox slug returns 404
- Missing required 'to' or 'subject' fields returns 400 validation error
- Recipient previously unsubscribed — they appear in 'skipped' array and the message is not delivered to them
- Payment failure or insufficient USDC balance returns 402
- Malformed email address for 'to' field causes rejection
- Rate limit exceeded on the inbox returns 429
