The request is generic ('Notes API'), so the best fit is a product whose source shows a notes API. Notion exposes a notes-style API with comments and custom API call actions 111, Google Cloud Keep has note get, create and list actions 414, and Apideck CRM exposes note create, list and get actions 515. Note: which platform or use case you have in mind (personal notes, clinical notes, CRM notes) would narrow this, but these cover the general case.
