## 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 workflows-agentdiet-dev-web-url-to-markdown-distiller-with-bm25-b0189ffb
```

Example prompt: Distill the Stripe documentation page at https://stripe.com/docs/api/charges into compact markdown using budget mode, focused on 'charge creation parameters', and keep it under 500 tokens.

## When to prefer this

Choose this endpoint when your AI agent needs to read and process web pages or documentation but must stay within a token budget or minimize LLM input costs. It is especially valuable when working with large documentation sites, API references, or any HTML-heavy content where only a portion is relevant. The BM25 budget mode makes it uniquely suited for targeted Q&A over web content. Prefer this over generic scrapers when you need both compression metrics (ROI proof) and multiple extraction modes (markdown, structured, skeleton, budget) in a single call.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- Invalid or malformed URL string — validation error on the url parameter
- max_tokens set below minimum of 20 — schema validation failure
- mode=budget used without a query parameter — may return unfiltered or empty excerpt
- Raw HTML provided but also a URL — ambiguous input, behavior may default to URL fetch
- Payment not processed (402) — request blocked until x402 micropayment is completed
- Webpage with heavy JavaScript rendering may not be fully captured by server-side fetch

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://workflows.agentdiet.dev/v1/docs-to-markdown)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), plus an 'roi_proof' block showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Optionally includes cache hit/miss status and billing details.
