Contains the payment challenge from a 402 Payment Required response. Forward the raw WWW-Authenticate: Payment header value verbatim. In response, you receive a payment credential that satisfies the challenge. Provide exactly one challenge per request.

Attributes

buyer_pays_gas_fees class-attribute instance-attribute 
buyer_pays_gas_fees: bool | None = None

Authorizes the service to sign a payment whose blockchain network (gas) fees are charged to your wallet, on top of the payment amount.

The challenge indicates who sponsors the network fees. When the challenge does not sponsor them, the service signs the payment only if this field is true. Otherwise it returns a validation error, so you can decide whether to pay the fees or obtain a challenge that sponsors them.

Optional. When omitted or false, you decline to pay network fees. This field has no effect on challenges that already sponsor the fees.

version instance-attribute 
version: str

The MPP protocol version, for example "1" or "2".

www_authenticate_headers instance-attribute 
www_authenticate_headers: list[str]

The raw WWW-Authenticate: Payment header value from the 402 response, passed verbatim. Provide exactly one entry. The service uses this value to generate the payment credential.
