# Integration Guide There are two approaches available for integrating with the CrossCurve MetaLayer service. Choose the one that best fits your tech stack and transaction control requirements. #### Direct Integration with REST API Use this method if you need full control over the process or are using a language other than TypeScript/JavaScript. #### Simplified Integration with SDK A client library designed for quick integration into JS/TS projects. It abstracts interaction with the MetaLayer API, provides type safety, and simplifies standard swap scenarios. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.crosscurve.fi/developer-documentation/integration-guide-old.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
