Claim This ListingPostalForm is a developer mail API and remote MCP server for creating physical-mail drafts from PDFs, letters, supported form workflows, and AI-agent output. Developers can create hosted-checkout drafts for human review, upload PDFs, quote and track orders, and use x402 or MPP machine-payment flows when direct payment is explicitly authorized. Use it when software needs to turn a digital document into real postal mail without building print, envelope, postage, and carrier-handoff infrastructure.
