A computer-implemented method, comprising:

• receiving, by a provider service, transaction data for a particular transaction with an enterprise website, wherein the transaction data is received using a cross-domain communications method;
• scraping, by the provider service, a plurality of transaction facilitation websites to identify a plurality of sets of transaction instrument terms for a plurality of registered transaction instruments;
• transmitting, by the provider service to a client device, a request to invoke an option selection language model stored on the client device, the request comprising the transaction data and the plurality of sets of transaction instrument terms;
• receiving, by the provider service, transaction instrument selection data generated by the option selection language model;
• and
• transmitting, by the provider service, the transaction instrument selection data using the cross-domain communications method.

A system, comprising:

• at least one computing device comprising at least one processor and at least one memory;
• and
• machine-readable instructions stored in the at least one memory that, when executed by the at least one processor, cause the at least one computing device to at least:
• receive transaction data for a particular transaction with an enterprise website, wherein the transaction data is received using a cross-domain communications method;
• transmit, to a client device, a request to invoke an option selection language model stored on the client device, the request comprising the transaction data;
• receive transaction instrument selection data generated by the option selection language model, wherein the transaction instrument selection data specifies at least a subset of a plurality of registered transaction instruments;
• and
• transmit the transaction instrument selection data using the cross-domain communications method.
