# UOS Genesis RAG Web Extraction

> UOS Genesis RAG Web Extraction is a paid API for AI agents from genesis.palsus2023.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-02).

Scrapes a public URL and returns structured, machine-readable content including text, links, headings, markdown, and metadata.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability uos-genesis-rag-web-extraction-f17819e9 -d '<json body>'
```

Example prompt: Can you scrape https://example.com and give me the full text, headings, and links in structured form?

## When to prefer this

Choose this endpoint when you need to fetch and structurally parse a public webpage into JSON-ready fields (text, markdown, links, headings) with micropayment-gated access via x402 and Base USDC. Prefer it over general-purpose HTTP fetch tools when you need clean, parsed output including markdown conversion and link extraction in a single call, and when operating in an autonomous agent context that already handles x402 payments.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — scrape fails with an error response
- URL points to a non-HTML resource (PDF, binary) — text extraction may be empty or malformed
- Page requires JavaScript rendering — static scraper may return incomplete or skeleton HTML
- Payment not attached or insufficient USDC balance — request rejected with 402
- Malformed URL input — request rejected with validation error

## How this service works

Autonomous paid machine utilities using x402 and Base USDC.

## Output

A JSON object containing the scraped page's URL, plain text body, markdown rendering, page title, list of headings, list of links, and a description field extracted from the page metadata.
