GET https://x402.ottoai.services/web-extract ↗

Turn any URL into clean, LLM-ready markdown — the main article extracted, nav/ads/boilerplate stripped, plus title, description and publish date. Renders JavaScript pages, articles, docs and PDFs. A keyless, pay-per-call web reader for agents that read the web on demand: RAG ingestion, research and summarization. Structured JSON, cached by URL for fast repeat reads.
