How this service works
Pay-per-call utility APIs for AI agents, settled in USDC via the x402 protocol.
Output
A JSON object with: 'ok' (boolean), 'url' (original URL), 'status' (HTTP status code), 'final_url' (after redirects), 'latency_ms' (response time in milliseconds), 'content_type', 'content_length', and 'redirect_chain' (array of intermediate URLs).
Example use cases
Validate affiliate links before publishing
“I'm about to post these product links in my newsletter—can you quickly check if they're all live and not broken, and tell me if any of them redirect somewhere unexpected?”
Monitor competitor website availability
“I need to know if our competitors' homepages are currently up and responding normally. Check each domain, give me the status codes, and let me know if response times seem slow.”
Audit internal service endpoints
“Can you probe these internal API endpoints and tell me which ones are returning errors, how fast they're responding, and if any of them are doing weird redirects that shouldn't be happening?”
Technical details
Endpoint
POSThttps://x402.nichospt.net/http-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, paid-per-call HTTP availability check with latency and redirect chain data for a single public URL. Prefer it over free monitoring tools when running inside an x402-enabled agent payment flow that already handles USDC micropayments automatically.
Side effects
- URL is unreachable or DNS fails — ok: false with error message
- Non-public/private IP URL rejected
- More than 5 redirects causes failure
- Malformed URL input returns validation error
- Payment not settled in USDC causes 402 rejection before processing
