We run the checks
Deterministic validators query live signals - DNS, TLS, GitHub, and the site itself - for exactly the categories your call covers.

Why Validex is different
Deterministic scoring
Every score comes from rule-based validators, not model judgment. The same target run twice produces the same evidence and the same score.
Evidence-backed
Every strength, weakness, and score ties back to a concrete signal - a DNS record, a TLS certificate, a GitHub API response - not a summary of a summary.
Agent-native
Built to be called directly by AI agents via the x402 protocol - no API keys, no signup, no dashboard. Call one category for a few cents or bundle the full analysis. Pay only for the job you run.
On-chain settlement
Payment settles in USDC on Algorand through a facilitator that co-signs as fee payer - callers only need USDC, no ALGO for gas.
