Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Wayback Machine
Query the Internet Archive's Wayback Machine for archived web pages.
When to Use
- User wants to see an old/archived version of a web page
- Checking if a URL/domain was previously active
- Retrieving historical page content
- Searching for all snapshots of a URL
- Comparing page content over time
Requirements
No API key required — Wayback Machine is free and public.

./scripts/wayback_search search "https://example.com" [-n 25] [--from 20200101] [--to 20231231]
check — Quick availability check
./scripts/wayback_search check "https://example.com"
latest — Fetch latest snapshot content
./scripts/wayback_search latest "https://example.com" [-f json]
