In 1995–1998, browser scripting, HTML forms, and CGI quietly acted like early web APIs—revealing integration pain points that later drove SOAP and formal web service contracts. Chapter 77 of our chronological web API history.
From the first HTTP requests to early browsers like Mosaic, the Web’s 1990–1994 era pioneered practical image+text workflows that foreshadowed today’s multimodal APIs.
From HTTP/0.9’s minimalist request format to early proxies and CGI, the Web’s 1990–1994 foundations quietly established patterns that modern edge runtime APIs use to deliver low-latency apps.
XML wasn’t yet a web standard in 1990–1994, but the early Web’s HTTP interfaces, CGI scripts, and MIME content types created the exact need XML later filled: predictable, self-describing data that could move cleanly between systems.
Before REST and JSON, CGI scripts turned early websites into programmable interfaces. From 1990–1994, CGI and server-side integration quietly shaped the first usable patterns of web APIs.
Between 1990 and 1994, CGI scripts turned the early Web from static documents into interactive services. This chapter explains how the first practical HTTP interfaces worked—requests as inputs, script output as responses—and how that pattern became the backbone of modern web APIs.
