Monzo released an interim API to comply with the Payment Services Directive (now officially law). While the company plans on adding all functionality of its interim API to its standard developer API, the interim API will ensure immediate compliance for companies managing account information.
ODesk claims to be the future of work, or more recently: "Work 3.0." So it should come as no surprise that the next version of work comes with an API. If you’re not familiar with the platform, oDesk provides contractors and companies with a hourly billing system which both verifies the work done for the company, and guarantees payment to the contractor.
