New HTTP QUERY Method Changes Everything

A 2026 internet standard that introduces the HTTP QUERY method to resolve long-standing limitations in API design. This new method is safe and idempotent, meaning it performs read-only operations that can be retried without side effects. Unlike GET, which is restricted by URL length limits and security risks, QUERY can transmit large, complex data structures within a request body. It improves upon the common POST workaround by allowing responses to be cached at the network edge using a key based on the request content. While server-side support is emerging in frameworks like Node.js and Fastify, the sources note that full browser and infrastructure integration is still ongoing.
