Kenward Uptime Check API
x402
Kenward Uptime Check API is a paid API for AI agents from pay.kenwardai.my.id, paid per call via x402, $0.025/call, status unknown (last checked 2026-10-21).
Performs a live HTTP probe against a public URL and returns reachability, HTTP status, TLS status, and latency — settled per-call in USDC via x402.

How this service works
Pay-per-call data settled in USDC on Base. No account, no API key, no human in the loop. Measured 2026-10-05: p50 89-105 ms end-to-end over the public internet; our own handling cost is reported per response in the X-Kenward-Serve-Ms header. Safe by construction: the server holds no private key (/health reports holds_keys=false), a signed payment is delivered once, and an unmeasured market answers UNKNOWN instead of a guess. Launch price: 0.025 USD (50% off 0.05) for the first 100 unique paying wallets (excluding the operator's own wallet).
Output
A JSON object with fields: url (the probed endpoint), reachable (boolean), http_status (integer), tls (boolean for HTTPS validity), latency_ms (round-trip latency in milliseconds), as_of (ISO 8601 timestamp of the probe), and boundary (a plain-language description of the measurement scope, e.g. 'active HTTP probe from one vantage point'). If the endpoint cannot be measured, the service returns UNKNOWN rather than guessing.
Example use cases
Pre-deploy health check for a staging endpoint
“Before I push my release, can you probe https://staging.myapp.com/healthz and confirm it's returning 200 with TLS working?”
Incident triage for a suspected outage
“Our users are reporting issues — can you check right now if https://api.mycompany.com/status is reachable and what HTTP status it's returning?”
Third-party dependency availability check
“I need to know if https://data.partner-service.io/v2/ping is currently up and how fast it's responding before I run my batch job.”
Technical details
Endpoint
GEThttps://pay.kenwardai.my.id/v1/uptime?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, single-shot HTTP reachability probe with no account setup or API key — paid per call in USDC via x402. Ideal for agent workflows that need on-demand uptime verification without subscribing to a monitoring SaaS. Best for confirming live status before critical operations, not for continuous scheduled monitoring at high frequency.
Side effects
- Target URL is unreachable — reachable returns false, http_status may be absent
- Invalid or non-public URL provided — likely a 4xx error from the API
- TLS certificate invalid — tls returns false
- Payment not settled or x402 flow fails — request is rejected before probing
- Unmeasured/unknown state — service returns UNKNOWN rather than fabricating a result
