URL safety check, scam signals: domain age, redirects and HTTPS

$0.01 per call · failed calls are never charged · no account or API key needed

Check a link before an agent opens or pays it: where it really leads (each redirect hop, the final URL), the destination domain's age, registrar and trust flags, HTTPS and security headers, and named risk signals (days-old domain, bare IP host, punycode look-alike, user@host trick, chains across many hosts). Heuristic signals from public facts, not a phishing blocklist. Use to vet links in emails, chats and scraped pages, or a payee's website.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/pack/url-safety?url=http%3A%2F%2Fgithub.com"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/pack/url-safety?url=http%3A%2F%2Fgithub.com&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
