Quick API health check for agents: send one public API endpoint URL and get a 3-sample spot check for $0.09 USDC on Base: grade A-F, score, production-ready yes/no, median/p95 latency, success rate and the top 3 issues w...
Use when an agent needs base block number. Returns Fetch the current Base mainnet block number from redundant public RPCs and return structured JSON with source and freshness metadata. $0.002.
Real-time L2 sequencer health across 12 chains (Base, Arbitrum, Optimism, zkSync, Blast, Linea, Mantle, Mode, Scroll, Taiko, Polygon zkEVM, Casper). Returns kernel-level P99/P95 RTT from eBPF probes, revert ratios (Base...
Which Base public RPCs serve a stale chain tip. Every 30s we ask all major public RPCs for eth_blockNumber in parallel and record how many blocks behind the fastest peer each was, plus latency and error rate. An RPC neve...

API/URL health check: up or down, HTTP status, latency, and whether the endpoint is a valid x402 paid endpoint.
Detect material public DNS answer changes with a deterministic hash. TTL-only changes do not count and no arbitrary resolver or AXFR operation is exposed. Base mainnet USDC
Liveness/latency pre-flight for a URL: is it up, HTTP status and class, response latency in ms, whether it redirects (and where), content-type and server.
HTTP ping: up or down, status and timings (DNS, TCP, TLS, TTFB): One live request to a URL with no redirect following: up or down (and why: DNS, timeout, refused, TLS), status, Location, timings in ms for DNS, TCP connec...
Extract page metadata from a public URL: title, meta description, canonical, language, OpenGraph/Twitter card tags, favicon, headings (h1-h3) and up to 200 absolute links.
High-precision network latency benchmark profiler: decomposes microsecond timing for DNS resolution, TCP handshake, TLS 1.3 negotiation, and TTFB roundtrip times for MCP servers and Base RPC endpoints ($0.75 USDC). Input...
AI-agent readiness audit, $0.001 USDC per call: How ready is a website for AI agents? Live checks of /llms.txt, robots.txt rules for 12 AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot…), sitemap.xml...
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 performa...
