API If you’ve used the Application Programme Interface (API) for our Pricing Tool previously, it will be well worth migrating over to the new version 5, which has a range of exciting new features and capabilities that you can access. If you haven’t used the API before, try it out now. It’s easy - you won’t have to log onto another BT system to access the Pricing Tool. To access the new version, email wholesale.pem@bt.com (see ‘PEM’ for more details).   Access Pricing Offers We regularly have special offers across our wide range of industry-leading Etherway access options.
