Arrangements for developing an application programming interface (API) are provided. A computing platform may train an artificial intelligence (AI) engine. The computing platform may receive a request to develop a new API. The computing may extract features of the new API. The computing platform may generate one or more similarity scores based on similarities between the extracted features of the new API and corresponding similar historical API features. The computing platform may output the new API based on solving a correlation matrix. The computing platform may test the API and output a validation score. The computing platform may deploy the API based on the validation score being equal to or exceeding a threshold.
