Web Capability API for AI Agents
AmbassadorNice8641 · reddit · 2026-07-19
The author developed a web capability API for AI agents that converts web pages into a structured JSON manifest. It returns clickable/fillable/submittable elements along with their parsed locators, and uses a requires field to express cross-action dependencies.
He argues that this approach is more reliable than simply returning page content or providing browser access, serving as a great supplement to existing browser tools. The project offers a hosted API, Python SDK, MCP server, and LangChain integration, along with a live demo and 50 free API calls per month.
