[docs]class StrictSendPathsCallBuilder(BaseCallBuilder): """Creates a new :class:`StrictSendPathsCallBuilder` pointed to server defined by horizon_url. Do not create this object directly, use :func:`stellar_sdk.server.Server.strict_send_paths`. The Stellar Network allows payments to be made across assets through path payments. A strict send path payment specifies a series of assets to route a payment through, from source asset (the asset debited from the payer) to destination asset (the asset credited to the payee). A strict send path search is specified using: - The source asset - The source amount - The destination assets or destination account. As part of the search, horizon will load a list of assets available to the source address and will find any payment paths from those source assets to the desired destination asset. The search's source_amount parameter will be used to determine if there a given path can satisfy a payment of the desired amount. See `Find Payment Paths <>`_ :param horizon_url: Horizon server URL. :param client: The client instance used to send request. :param source_asset: The asset to be sent. :param source_amount: The amount, denominated in the source asset, that any returned path should be able to satisfy. :param destination: The destination account or the destination assets.
