x402Factory.ai - Where everything becomes an endpoint

Base → Solana USDC microbridge discovery. Default example uses 1.00 USDC deposited to the Base bridge wallet. Provide a Solana receiver address and an amount (min 0.01 USDC, max 50.00 USDC, steps of 0.01) to create a concrete bridge quote. The bridge charges a 2.5% commission; the remainder is delivered as USDC on Solana.

Base send endpoint discovery. Example quote uses 1.0 USDC (1,000,000 atomics) paid to the server address for documentation and x402scan registration. For real sends, provide receiver and amountAtomic (and optionally a token contract) so the payment schema targets your chosen receiver and token directly. On Base there is geen ATA-concept; elke 0x wallet kan tokens ontvangen zolang het een geldig adres is en het tokencontract een standaard transfer ondersteunt.
