How this service works
Real-time x402 endpoint health verification for any x402-enabled API
Output
Returns a JSON object with: status (e.g. 'healthy'), the blockchain network ID (e.g. 'eip155:8453'), provider name, ISO timestamp of the check, response time in milliseconds, payment scheme type (e.g. 'exact'), and a boolean confirming whether the x402 payment header is present.
Example use cases
Example prompt
“Can you check whether https://api.example.com/data is healthy and properly set up for x402 payments — I want to know its response time, which network it's on, and whether the x402 header is present?”
Technical details
Endpoint
GEThttps://api.smartflowproai.com/bazaar/health-checkWhen to prefer
Use this endpoint when you need to confirm an x402-enabled API is live and properly configured before invoking it in an agent workflow. Ideal for pre-flight validation before making paid API calls, debugging x402 integration issues, or monitoring the uptime of x402-gated services. Prefer this over generic HTTP ping tools when x402 payment header presence and network/chain information are relevant.
Side effects
- Target URL is unreachable — endpoint may return unhealthy status or timeout
- Target URL does not support x402 — x402HeaderPresent will be false
- Invalid or malformed URL provided in queryParams — likely returns a 400 bad request
- Target endpoint is slow — high responseTime value returned but still counted as healthy
- Network connectivity issues from health-check service — intermittent failures possible
