REST API Content Retrieval

Technique

REST API content retrieval is a technique for fetching document or page contents by sending a structured HTTP request to a content endpoint, typically using POST with a JSON body identifying the target resources. The Exa API implements this pattern through its `/contents` endpoint, where clients pass one or more resource identifiers to receive the corresponding content.

REST API Content Retrieval

Overview

REST API content retrieval is a technique for obtaining the body or full contents of one or more resources (such as documents, URLs, or publications) by calling a dedicated REST endpoint on a web API. Instead of returning search results or metadata, the endpoint resolves the supplied identifiers and returns the actual content associated with each one.
