How this service works
Pay-per-call x402 data services on Base mainnet
Output
Returns the health status of the submitted URL, including whether it is reachable and its HTTP response code or error state.
Example use cases
Pre-flight API dependency check
“Before we start the workflow, can you verify that https://payments.myapp.com/api/v2/status is live and responding?”
Broken link triage in content pipeline
“I have this URL https://blog.acme.com/2023/launch-post — can you check if it's still up or if it's returning an error?”
Third-party service availability check
“Can you quickly check if https://cdn.partner.io/assets/bundle.js is reachable before I deploy — I need to know if the CDN is healthy.”
Technical details
Endpoint
POSThttps://temporary-prompt-onyx-8ryoe7p.vercel.app/v1/url_healthWhen to prefer
Use this endpoint when you need a quick, pay-per-call HTTP health probe of a single URL without setting up persistent monitoring infrastructure. Ideal for lightweight pre-flight checks in agent workflows before calling downstream dependencies.
Side effects
- URL is malformed or missing scheme — returns validation error
- Target URL times out — returns unreachable/timeout status
- Target URL returns 4xx or 5xx — reflected in health result
- Payment not processed — 402 response before health data is returned
- Service temporarily unavailable on provider side
