What it does
Last night Pay-per-Crawl was a WordPress plugin that started as a comment on TikTok, with two real payments behind it. This afternoon the same gate runs on WordPress, Drupal, Laravel, Next.js, Node, Cloudflare, nginx, Caddy, Traefik and Python, and it is published on npm, PyPI, Packagist and drupal.org. Every edition settled two real payments on Base mainnet before we released it. We are proud of this one, so here is exactly what shipped and what it took. The behaviour is identical on every stack. Humans and reverse-DNS-verified search engines read free. AI crawlers, SEO crawlers and scripts get an HTTP 402 carrying an x402 v2 header, a v1 body and an MPP challenge. They pay USDC on Base,…from forgemesh.io

Crawlie – Free open-source SEO audit tool for humans and agentsJun 2026 · github.com · ▲20With AI, it's faster than ever to ship a marketing site... but most of what gets generated is slop that was never built to be found. Plus the tools meant to catch that fall short: most SEO auditors cost money, don't play nicely with your agents, or tell you what's wrong without telling you how to actually rank for SEO and GEO (Generative Engine Optimization: being cited by AI search like ChatGPT, Perplexity, and Google AI Overviews). crawlie fixes that! It's 100% free, it's local-first, it's agent-native (MCP baked in!), and every issue it finds comes with why it matters and how to fix it.
