Fecha de publicación: 13/12/2018 Fuente: WIPO "apis" The invention relates to providing API interoperability. An embodiment of the present invention is directed to increasing API productivity by chaining (or sequencing) APIs together to accomplish multiple operations. The innovative system enables APIs to be strung together, in a way that eliminates or reduces a user's need to visit and/or invoke multiple applications and/or APIs. An embodiment of the present invention is directed to expanding a traditional usage of point-to-point API invocation. The innovative system may define a classification protocol to enable API providers and/or creators to register an API by a command type (e.g., entitlement, query, data, etc.). Each command type may have a minimum set of mandatory operations that an API may be required to expose. By adhering to the contract, APIs may be handled generically, without knowing which system and/or app created the API.
