The full API endpoint reference is included at the end of the documentation; the product APIs represent typical integrations for various use cases. If you fit one of the use cases, after reading through the introductions start with the relevant product APIs. Any Questions about the Crypto api can be directed to Fundamental Interactions support email: [https://fundamental-interactions-inc.gitbook.io/websocket-api/](https://fi-crypto-api.gitbook.io/crypto-api/) ### APIs INTRODUCTION APIs allows authorized individuals to automate many tasks related to Crypto API calls of various types. This means being able to initiate various calls. ### REST-ISH Crypto APIs are "REST-ish" APIs that conform as strictly as possible with the [JSONAPI](http://jsonapi.org/format/) specification. It's important to note that while we strive to be as strict as possible in our adoption of the JSONAPI specification, for the sake of convenience, there are places where slight deviations are made. In general, and in our own experience writing front-ends with these APIs, said deviations aren't particularly difficult to work with. ### LANGUAGE-SPECIFIC SDKS No language-specific SDKs are available nor is there any plan to create them. The reason JSONAPI is being used and being implemented as strictly as possible is to allow developers to use common, generic libraries to consume API resources and relationships. ### GETTING STARTED Requests should use `https://mid-crypto-dev-enc.fi-edition.com/api/v1`.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://fi-crypto-api.gitbook.io/crypto-api/master.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
