Struct X402V2PaymentRequirements 

pub struct X402V2PaymentRequirements {
    pub amount: String,

    pub scheme: X402v2PaymentRequirementsScheme,
}

The x402 v2 payment requirements. Uses CAIP-2 network identifiers and supports exact, upto, and batch-settlement schemes. Carries only the payment fields (no resource metadata — that is in the enclosing x402V2PaymentPayload.resource).

Fields

amount: String

The amount to pay for the resource in atomic units of the payment asset.

asset: BlockchainAddress

The asset to pay with.

    For EVM networks, the asset will be a 0x-prefixed, checksum EVM address.

    For Solana-based networks, the asset will be a base58-encoded Solana address.

extra: Map<String, Value>

The optional additional scheme-specific payment info.

max_timeout_seconds: i64

The maximum time in seconds for the resource server to respond.

network: X402v2Network

The network of the blockchain to send payment on in CAIP-2 format.

pay_to: BlockchainAddress

The destination to pay value to.

    For EVM networks, payTo will be a 0x-prefixed, checksum EVM address.

    For Solana-based networks, payTo will be a base58-encoded Solana address.

scheme: X402v2PaymentRequirementsScheme

The scheme of the payment protocol to use. Supported schemes are exact, upto, and batch-settlement.
