How this service works
54ch10: pre-interact URL check. Paste a link, get brief + domain + page. Taste /v1/open/free. 80 calls for $1. Wire in 30s. Analytics-only tooling. Not financial advice.
Output
Returns a JSON object with fields: ok (boolean), tier, domain, age_days (integer days since registration), registrar name, registered (boolean), and a disclaimer. Higher-level risk signals such as phishing, scam, or honeypot flags may be included depending on service tier.
Example use cases
Phishing URL check before wallet connect
“I just got a Discord DM with a link to 'metamask-claim-rewards.net' — can you check if that domain is a known phishing site or scam before I do anything with it?”
Due diligence on a new DeFi protocol site
“I'm thinking about using a DeFi protocol at 'velodrome-finance-v3.xyz' — can you pull a reputation brief on that domain and tell me how old it is and who registered it?”
Automated safety screen for NFT marketplace URL
“Before my agent approves any transaction on 'opensea-special-drop.com', run a domain risk check on it and flag it if it looks suspicious or was registered recently.”
Technical details
Endpoint
GEThttps://54ch10.uk/v1/whoisWhen to prefer
Choose this endpoint when you need a quick, structured pre-interaction reputation brief for a domain before a user clicks a link, connects a wallet, or approves a crypto transaction. It is especially well-suited for web3 and DeFi safety workflows where phishing domains, honeypots, and scam sites are common threats. Prefer this over generic WHOIS tools when you need risk-oriented output (not just registration data) in a machine-readable format suitable for automated agent decision-making.
Side effects
- Domain not found or unregistered — may return registered: false with limited data
- Invalid or malformed domain string — likely 400 or error in ok field
- Payment not included or insufficient — 402 response required for x402 protocol
- Rate limiting or service unavailability — 5xx responses possible
- Domain is very new with no history — age_days near zero, limited signals
