Content negotiation serves raw Markdown to agents, skipping the reconversion tax entirely.
Checks eight layers in one go — from plain HTTP reachability to on‑chain ERC‑8004 lookups and x402 payment detection — and even exposes a /mcp POST API so other tools can trigger programmatic validation. The built-in MCP server and agent-lookup features are clever for this niche ecosystem; what I'd want next is clearer detection heuristics, error modes and false-positive handling so teams can trust automated scans in CI.
Markdown-for-Agents proxy for private/internal sites, but Jina.ai and Firecrawl cover most use cases.
OpenAPI for agent verification with risk scoring before merge — ambitious standardization play.
Returns markdown and element refs instead of raw HTML—one API call beats 25 lines of Puppeteer.
Browser scraper service with warm Chrome pool—but Puppeteer and Playwright do this better.
