How this service works
Pay-per-download PDF documents in USDC on Base via the x402 protocol. Settlement runs through the public x402 facilitator; a direct transfer + tx-hash route is also accepted. Failed delivery is refunded.
Output
Returns the raw binary content of the purchased PDF document (binary stream). If payment is invalid or delivery fails, a refund is issued and an error is returned.
Example use cases
Purchasing a gated research PDF
“I want to download the bromley27 research document — please pay the $0.10 USDC fee using my x402 payment and hand me the PDF file.”
Automated document acquisition with tx hash
“I already sent 0.10 USDC to the payTo address for the bromley27 PDF — here's my transaction hash, use it to claim and download the document for me.”
Agent-driven content purchase pipeline
“As part of the research workflow, purchase the bromley27 PDF from the Earn Shop for $0.10 USDC using x402 and save the downloaded file locally.”

Use this endpoint when you need to programmatically purchase and retrieve a specific gated PDF document (bromley27) using a USDC micropayment on Base via the x402 protocol or a direct transfer. Prefer this over manual browser-based purchases when automating document acquisition in an agent workflow. Not suitable for free documents, non-PDF content, or payment methods other than USDC on Base.
