How this service works
Guardian Host Brief — before you pay a resource URL, measure host hygiene (https, IP host, TLD shape, self-pay). No historical blacklist — patterns only. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a host hygiene brief covering pattern-based signals: whether the host uses HTTPS, whether the host is IP-based rather than a named domain, TLD shape assessment, and self-pay pattern detection. No historical blacklist data — purely structural/pattern analysis of the host at call time.
Example use cases
Pre-payment host safety gate
“I'm about to pay the x402 resource at https://someskill.xyz/api/run — can you check whether the host looks safe first? Flag anything weird like an IP address instead of a domain, a dodgy TLD, or missing HTTPS.”
Agentic marketplace URL vetting
“Before my agent pays any skill listed on Agentic Market, I want it to first screen the resource URL's host hygiene — check https://newvendor.io/api/generate using a GET and tell me if the host passes basic safety patterns.”
Self-pay loop detection
“Can you run a host hygiene check on https://pay.myownservice.dev/api/respond to see if it looks like a self-pay setup? I want to catch any circular payment traps before my agent sends funds.”
Technical details
Endpoint
GEThttps://cyre.dev/api/hostWhen to prefer
Use this endpoint when you need a fast, lightweight pre-payment host check based purely on structural/pattern signals (HTTPS, IP vs. named host, TLD shape, self-pay patterns) and do not need historical blacklist data or full counterparty risk scoring. Ideal as a first-pass gate before calling heavier risk endpoints like Guardian Pay-route Oracle or Guardian Bazaar Scan.
Side effects
- Missing or invalid 'url' query parameter returns an error
- Non-HTTP type value rejected by schema
- HTTP method not in allowed enum (GET, HEAD, DELETE) causes validation failure
- Malformed URL that cannot be parsed into host components may return an error or empty signals
- Network timeout if host probe is required
