Vercel Experiments developer resources
This page is the developer portal for Vercel Experiments: programmatic access to the experiment catalog, agent-readable files, and tooling that sits beside the HTML docs. Use it when integrating the catalog into scripts, IDEs, or AI agents instead of scraping the marketing site.
The hub API exposes catalog metadata only. Individual experiment Route Handlers remain inside each standalone app under apps/experiments/<slug>/ on GitHub. Start with the documentation when you need human-oriented guides.
- Public REST API
List and fetch published experiment metadata as JSON. Read-only, no auth required.
- OpenAPI specification
Machine-readable schema with operationIds, typed parameters, and JSON error models for function calling.
- MCP server
Model Context Protocol endpoint for listing pages, fetching docs, and searching the catalog.
- llms.txt
Agent entry file with when-to-use guidance and curated links to Markdown resources.
- Markdown negotiation
