Live Deduplicated, quality-scored data feeds for AI agents and developers: the MCP server registry and the live x402 service catalog, with change-deltas and liveness probes. Free previews; full data paid per call via x402.

Live A URL in, clean LLM-ready markdown out — a free, agent-native web reader. Call it over plain HTTP or install it as an MCP server (read_url / read_url_preview). A polite reader by design: respects robots.txt, identifies honestly, never bypasses anti-bot, CAPTCHA or paywalls.
Free · MCP server · no account, no API key 04 Agent Risk
Live Verify an ERC-8004 agent on Base before you pay it: pass an agentId, get a 0–100 risk score, a low/medium/high band, and the reasons — owner mismatch, inconsistent registrations, orphaned identity, dead endpoints. Read-only on-chain checks, no key. Free HTTP endpoints plus an assess_agent_risk MCP tool.

Live Scan a URL for WCAG 2.2 (ADA) accessibility issues — missing alt text, unlabeled form fields, heading order, zoom blocking and more — each mapped to its Success Criterion with a fix. Honest about coverage: it states what automated testing cannot catch and never claims compliance. Free HTTP /scan endpoint plus an MCP server.

Live Scan a URL for GDPR / CCPA / ePrivacy privacy signals — which third-party trackers are present, whether a consent banner, a privacy-policy link and a CCPA "Do Not Sell" link exist, cookie attributes and HTTPS — each tied to its regulation with a fix. Honest about coverage: it cannot confirm pre-consent tracker firing and never claims compliance. Free HTTP /scan endpoint plus an MCP server.
