Each API contract should posses a single image that symbolizes the purpose and intent of the API contract, as well as the interested parties involved in the creation of an API contract, or possibly the target of an API contract. This image will help make an API contract more relevant as part of catalogs, directories, and other discovery mechanisms.
The image for an API contract may be as simple as the logo of a company, but ideally should also reflect the business uses for the APIs an API contract possess. Designing icons and imagery that reflects a domain, line of business, as well as even team involved with an API contract will help make it easy to connect when discovering.
An image goes a long way to formalize and build trust in an API contract. Humans respond to symbology and taking the time to apply a simple yet useful image representation for an API contract can go a long way with stakeholders. Don’t spend too much time here, but a little investment in images will help a contract stand out in a sea of API contracts.
