Agreements provide an opportunity for institutions to negotiate to protect their customers' interests and offer aggregators the opportunity to provide a robust service. Aggregators who agree with information providers to extract data without using an OFX standard may reach a lower level of consensual relationship; therefore, "screen scraping" may be used to obtain account data, but for business or other reasons, the aggregator may decide to obtain prior consent and negotiate the terms on which customer data is made available. "Screen scraping" without consent by the content provider has the advantage of allowing subscribers to view almost any and all accounts they happen to have opened anywhere on the Internet through one website.
