How this service works
AgentHub provides low-cost x402 utilities for AI agents: security scanning, validation, temporary storage, page hosting, and public endpoint inspection.
Output
A JSON object with a boolean 'ok' field indicating success, the resolved 'host' string, and the HTTP 'status' code returned by the inspected endpoint.
Example use cases
Pre-call validation for external APIs
“Before my agent tries to call that third-party API endpoint, can you quickly check if it's actually up and responding? I need to know the host and status code so we don't waste time on failed requests.”
Website uptime monitoring for alerts
“I want my agent to periodically check if our main website and backup domains are still live and returning normal status codes. If anything goes down, flag it for me right away.”
Dynamic endpoint discovery and health check
“My agent is about to use a URL that a user provided — can you validate that it's a real, responding endpoint first? Just give me the host it resolves to and the HTTP status so I know it's safe to proceed.”
Technical details
Endpoint
POSThttps://3dprintedcat.com/agenthub-link.phpWhen to prefer
Use this endpoint when an AI agent needs a quick, low-cost ($0.003 USDC) check on whether a public URL or host is live and what HTTP status it returns, especially within an x402 micropayment workflow where lightweight utility calls are expected.
Side effects
- Host unreachable or DNS failure — ok: false with error details
- Invalid or malformed URL input — validation error returned
- Target endpoint returns non-2xx status — status reflected in response with ok: false
- Payment not processed — x402 payment required error before execution
- Timeout if remote host is slow to respond
