Latency Probe
x402
Latency Probe is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Sends three sequential timed HTTP GET requests to a URL from Cloudflare's edge and reports min/avg/max latency, jitter, per-attempt status, response size, and server/CDN header.

How this service works
Latency probe: three sequential timed requests to a URL from Cloudflare's edge, reporting min/avg/max/jitter in milliseconds, the status of each attempt, response size, and the server/CDN header. Cheap synthetic performance sampling for status dashboards and vendor SLAs. $0.01 per probe.
Output
Returns min, average, and max round-trip latency in milliseconds across three sequential requests, jitter, the HTTP status code for each individual attempt, the response body size in bytes, and the Server or CDN header returned by the target — giving a lightweight synthetic performance snapshot from Cloudflare's edge.
Example use cases
Status dashboard synthetic check
“Run a latency probe on https://status.myapp.com/ping and give me the min, avg, max, and jitter so I can update my status dashboard.”
Vendor SLA verification
“I need to verify our vendor's SLA — probe https://vendor-api.example.com/v1/ping three times from the edge and tell me if their average response time is under 200ms, plus show me the server header.”
Pre-launch performance baseline
“Before we go live, can you measure the latency of https://newproduct.acme.io/api/ready from Cloudflare's edge and report back the min, max, average, jitter, and response size for each attempt?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/monitor/latencyWhen to prefer
Choose this endpoint when you need cheap, quick synthetic latency sampling from a global Cloudflare edge node — ideal for status dashboards, SLA spot-checks, and CDN/server identification. Prefer it over full uptime monitors when you want a one-shot multi-sample benchmark without setting up continuous polling infrastructure. It's particularly useful when you also need jitter data and server header inspection in a single cheap ($0.01) call.
Side effects
- Target URL is unreachable or returns connection errors — individual attempt statuses reflect failures, latency may be null or maxed out
- Invalid or malformed URL input causes a 4xx error from the probe endpoint
- Target server rate-limits or blocks Cloudflare edge IPs, resulting in non-2xx statuses
- DNS resolution failures for the target URL produce error results per attempt
- Probe itself times out if the target is extremely slow, capping reported latency
