Endpoint
POSThttps://palmyr.ai/email/attachments/%7BattachmentId%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs to programmatically retrieve a specific email attachment by its ID from the Palmyr email infrastructure, particularly in agentic workflows where attachments must be fetched and processed autonomously using USDC micropayments via x402.
Side effects
- Attachment not found — invalid or expired attachmentId returns 404
- Payment failure — insufficient USDC balance or x402 payment rejected
- Unauthorized access — attachment belongs to a different account
- Attachment too large — timeout or payload size limit exceeded
- Network error — upstream email provider unavailable
