## 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 llms-generator-agentdiet-dev-web-url-html-distiller-with-bm25-budget-9c254370 -d '<json body>'
```

Example prompt: Fetch and distill https://stripe.com/docs/payments into compact markdown, keeping it under 800 tokens and focusing on the query 'payment intents API'.

## When to prefer this

Choose this endpoint when an AI agent needs to inject live web content into a limited LLM context window and must control token cost precisely. It is especially valuable over generic scrapers when you need BM25-ranked relevance filtering (mode=budget with a query), or when you want ROI proof of compression. Prefer it over raw HTML fetching when the downstream consumer is an LLM that needs clean, structured, or outline-form content rather than full HTML. The $0.001/call pricing and built-in caching make it cost-effective for repeated lookups.

## Known failure modes

- URL unreachable or returns non-200 status — distillation fails with error status
- max_tokens set below 20 — rejected by schema validation
- mode=budget used without a query field — BM25 ranking has no focus term
- HTML field empty and URL field missing — required 'url' field not satisfied
- Page behind auth wall or CAPTCHA — fetch returns empty or blocked content
- Token budget too tight for meaningful content — output may be truncated to near-empty

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt depending on mode), an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier, plus optional cache status (HIT/MISS) and billing details.
