HTTP

HTTP (Hypertext Transfer Protocol) is the foundation-level protocol for data communication on the World Wide Web, defining how messages are formatted and transmitted between clients and servers. It operates as a request-response protocol enabling browsers, APIs, and other clients to interact with web servers using standard methods like GET, POST, PUT, and DELETE.

HTTP is profiled on the APIs.io network. Tagged areas include Networking, Protocol, Standards, and Web.

The HTTP catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
