# Web URL Distillation to Agent-Ready Tokens (RAG Chunk)

> Web URL Distillation to Agent-Ready Tokens (RAG Chunk) is a paid API for AI agents from github-audit.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches and distills a web URL or raw HTML into compact, token-efficient markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt for AI agent consumption.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 github-audit-agentdiet-dev-web-url-distillation-to-agent-ready-tokens-59b3acd7
```

Example prompt: Distill the webpage at https://stripe.com/docs/payments into compact markdown, keeping it under 800 tokens and focusing on the topic 'payment intents'.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web content but must stay within a token budget or reduce LLM costs. It is particularly well-suited for RAG pipelines that fetch live web pages, agent workflows that need structured or skeleton views of documentation, and scenarios where BM25-ranked excerpts allow focusing on a specific query topic. Prefer it over generic scraping tools when token efficiency and cost-ROI proof are important.

## Known failure modes

- URL is unreachable or returns non-200 status — fetch fails with error status
- URL contains no extractable text (e.g. pure JS SPA with no SSR) — returns empty or minimal distillation
- max_tokens set too low — may return truncated or near-empty output
- mode=budget without a query string — BM25 ranking has no focus, falls back to generic truncation
- Raw HTML payload malformed — parser may produce garbled output
- Payment not authorized (HTTP 402) — request blocked until payment fulfilled

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://github-audit.agentdiet.dev/v1/rag-chunk)

## Output

Returns a JSON object with a 'data' field containing the distilled content in the requested mode (markdown text, structured JSON tables/metadata, skeleton outline, or BM25 excerpt), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes optional cache hit/miss status and billing details.
