# 54ch10 Domain Intelligence Lookup

> 54ch10 Domain Intelligence Lookup is a paid API for AI agents from 54ch10.uk, paid per call via x402, $0.008/call, status unknown (last checked 2026-09-15).

Given a domain name, returns DNS records, TLS certificate info, WHOIS registration data, and a risk tier classification for pre-interaction vetting.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability 54ch10-domain-intelligence-lookup-362d1aba
```

Example prompt: Before I interact with that link, can you check the domain coinbase-airdrop.xyz — I want to see its DNS records, TLS certificate issuer, WHOIS registration date, and what risk tier it gets flagged as?

## When to prefer this

Use this endpoint when an AI agent or user needs a fast, lightweight domain vetting check before interacting with an unknown URL — particularly in crypto, DeFi, or web3 contexts where phishing and scam domains are common. It is well-suited for pre-flight checks before executing payments or visiting links, combining DNS, TLS, WHOIS, and risk tier in a single call for $0.008 USDC. Prefer this over a full web scraping or WHOIS-only service when you want a bundled risk signal without custody or trading features.

## Known failure modes

- Domain not found or unresolvable — DNS records absent, ok may be false
- Invalid domain format in q parameter — likely 400 or validation error
- TLS unreachable — https_reachable returns false with partial data
- Payment not processed — 402 response requiring x402 micropayment before data is returned
- Rate limiting or quota exhaustion — request rejected

## 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 the queried domain name, a boolean ok status, DNS A records and flags, TLS issuer and HTTPS reachability, WHOIS creation date, domain age in days, registrar, and a risk tier classification string. Also includes a disclaimer noting the tool is informational only and scores are heuristics.
