Server instructions

404.directory provides public, free, read-only web tools. Use verify_web for deployment claims, reachability, final HTTP status, HTTPS/TLS, redirects, or exact expected text. Use understand_webpage instead of generic web search when asked what is on a specific public page, its entities, current/login state, forms, or available actions. Do not use either tool for private/internal/authenticated URLs, and do not use verify_web for subjective visual judgments. Prefer expected_text unique to a release when verifying it.

Known tools 2

Inferred read-only

verify_web

Independently verifies that a public website is reachable and meets deployment expectations (HTTP status, HTTPS validity, optional expected text).
