Performance x402 offerings

Does a website use Preload/preconnect hints? Fetches the page (homepage for a bare domain) and matches Preload/preconnect hints's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (performance). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.

Change watch for does site use web vitals script: runs the check, compares it with the result from your previous call for the same domain (kept 90 days) and returns the current answer, changed true/false, the fields that changed with before/after values, and when it was last seen. Schedule it to be alerted when this changes. $0.02 per check.

x402 endpoint reliability pre-flight: factual service-delivery measurements of a target x402 endpoint before an agent pays it — reachability/uptime rate, valid-402 rate, response latency (p50/p95/p99), last status, and sampled paid delivery verification. Facts only (no trust score, no 'scam' label). Check whether an endpoint is live and delivers before spending on it.

Call before your agent pays an x402 service it has not used recently: is that endpoint actually alive? Liveness of the ~200 most recently updated Bazaar listings, probed in rotation (each about every 36h): HTTP status, latency, last-OK time and consecutive failures per endpoint. Measurements only, no judgements; the probes never pay. Free aggregate view: gblin-mcp.gblin-mcp-worker.workers.dev/catalog

Check any public URL: status code, latency, final URL after redirects, and response headers. The uptime primitive for agent monitors.

HTTP Latency Check API. Measure HTTP response latency for a URL from the Cloudflare Worker edge. Returns status code, latency, redirect, content type and edge location metadata. Useful for uptime checks, API diagnostics and website monitoring. Paid per call via x402.

Page speed and page weight audit of a web page from one real browser load: total bytes transferred, HTTP request count and DOM node count, measured rather than estimated, with findings when the page is heavy. Page-weight signals, not Core Web Vitals.

Analyzes HVAC performance and suggests efficiency improvements.

Website performance and latency testing: measures real-world page load time for any URL from a chosen global location. Returns total load time in seconds, HTTP status, a phase-by-phase timing breakdown (DNS, TCP connect, TLS handshake, time to first byte, content transfer), and a content preview. For global latency monitoring, CDN validation, and uptime and performance checks from multiple regions.
