​
Overview

Your agent can send money to anyone with a Venmo or PayPal account using the /send-payment endpoint. The payment is funded with USDC on Base via x402 and delivered to the recipient on their payment platform.

​
How it works

1

Agent calls /send-payment

Your agent makes an x402 request to GET /send-payment with the amount, platform, and recipient.
2

Payment is queued

Laso Finance accepts the USDC payment and queues the Venmo/PayPal transfer for processing.
3

Recipient gets paid

The recipient receives funds in their Venmo or PayPal balance.
