Service overview

What is PostAgent?

Print and mail physical US letters (PDF, HTML, Markdown, DOCX, or image) and postcards via USPS, paid in USDC — with certified/registered proof options and standalone address verification at POST /v1/verify. Integration flow: POST /v1/documents to upload, POST /v1/quotes to lock a fixed USDC price for a recipient, then pay the returned per-quote x402 URL to create and mail the piece. Price is fixed per quote.

Level up your agent by giving it access to thousands of services. All payable per-request via x402. No API keys, no accounts.

Paste into your agentic chat and let your agent guide you.
