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
A binary PDF file is returned directly in the response body upon successful payment verification. If payment settlement fails or delivery cannot be completed, a refund is issued and no file is returned.
Example use cases
Purchase gated research report
“Buy me the PDF research report listed at the Earn Shop for 0.10 USDC using my x402 payment — I want the actual file downloaded so I can read it.”
Automated content delivery bot
“Every time a user submits a valid USDC transaction hash for the /buy/ukrr listing, fetch the corresponding PDF from Earn Shop and deliver it to them automatically.”
Direct transfer PDF purchase
“I already sent 0.10 USDC on Base to the payTo address — here's the tx hash, use it to claim and download the PDF from the Earn Shop.”

Endpoint
POSThttps://46-225-73-168.sslip.io/buy/ukrrWhen to prefer
Use this endpoint when you need to programmatically purchase and retrieve a specific pay-per-download PDF document using USDC micropayments on the Base network via the x402 protocol or a direct on-chain transfer. It is ideal for agents automating crypto-native content purchases where traditional subscription or API-key billing is not available.
Side effects
- Invalid or unconfirmed tx hash — payment not recognized, no file delivered
- Insufficient USDC amount in transfer — settlement rejected
- Malformed x402 payment payload (bad base64 or JSON) — 400 error
- Payment already used (replay) — duplicate payment rejected
- Network or blockchain congestion causing settlement timeout
- File delivery failure triggers automatic refund
