How this service works
Autonomous infrastructure for AI agents — pay with USDC on Solana or Base via x402.
Output
A confirmation object containing the sent message ID, delivery status, and timestamp indicating the email was successfully posted to the specified inbox.
Example use cases
Autonomous customer support agent
“Send a follow-up email from our support inbox to customers who haven't replied within 48 hours, letting them know we're here to help and asking if they need anything else.”
AI-powered newsletter distribution
“Have my agent send this week's newsletter from our marketing inbox to all subscribers on our list, personalizing each message with their company name and keeping track of delivery confirmations.”
Workflow automation for deal closes
“When a deal is signed, have my agent automatically send a confirmation email from our sales inbox to the client with the contract details and next steps, then log the message ID for our records.”
Technical details
Endpoint
GEThttps://palmyr.ai/email/inboxes/%7Bid%7D/messagesWhen to prefer
Choose this endpoint when an AI agent needs to programmatically send email from a Palmyr-managed inbox and can pay per-message via USDC micropayments on Solana or Base using the x402 protocol — particularly in autonomous agent workflows where traditional OAuth email APIs are unsuitable.
Side effects
- Invalid or non-existent inbox ID returns 404 not found
- Insufficient USDC balance or failed x402 payment returns 402 payment required
- Malformed message body or missing required fields returns 400 bad request
- Unauthorized access to inbox returns 401 or 403
- Rate limiting on message sending returns 429 too many requests
