X402PaymentRequirements

Defined in: src/x402/types.ts:128

One acceptable payment method, as advertised by the resource server.

Field encoding follows the wire format exactly:

• amount is a decimal string of atomic token units (uint256-safe).
• asset and payTo are 0x-prefixed addresses; case is not normalised at this layer (the verifier MUST checksum-compare).
• maxTimeoutSeconds is the max wall-clock time the client may take to produce a signed payload after receiving the 402 response.

extra is required (matching @x402/core) so that producers always provide the EIP-712 domain hint needed for signature verification. The most common shape is X402ExactEvmExtra.
