Example use cases
On-chain paid data retrieval
“Pull the monthly observations from Vauban Pay using my Base mainnet wallet — pay the $0.05 USDC fee automatically and save the receipt so I can verify the transaction later.”
Testing x402 micropayment flow
“I want to test Vauban Pay's pay-per-call API on Base mainnet — fetch the monthly observations endpoint, pay the 5-cent USDC fee, and show me what the receipt looks like.”
Automated agent data subscription
“Every month, have my agent call Vauban Pay's monthly observations endpoint on Base, pay the $0.05 USDC fee each time, and log the returned data along with the on-chain payment receipt.”

Endpoint
GEThttps://pay.vauban.tech/x402-base-mainnet/v1/observations/monthly-v1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to retrieve monthly observations data and want on-chain payment proof via the x402 protocol on Base mainnet. It is ideal for AI agents that need to autonomously pay for data access using USDC micropayments and retain verifiable receipts, especially in blockchain-native workflows where auditability of each API call matters.
