## 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-html-url-to-markdown-distiller-with-bm25-ad6cb66c -d '<json body>'
```

Example prompt: Fetch the Stripe docs page at stripe.com/docs/payments and distill it into markdown using budget mode, focused on the query 'payment intents', with a max of 500 tokens.

## When to prefer this

Choose this endpoint when you need to convert a live URL or raw HTML into compact, agent-friendly Markdown while staying within a token budget. It is especially valuable when LLM context costs matter, as the BM25 budget mode lets you filter content to only the most query-relevant tokens. Prefer it over generic scraping tools when you need ROI metrics on compression and token savings, or when you want structured JSON tables or skeleton outlines rather than raw HTML.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- Raw HTML is malformed or empty — distillation may produce sparse or empty output
- BM25 query provided without mode=budget — query may be ignored
- max_tokens set below minimum of 20 — request rejected with validation error
- Requested URL is paywalled or bot-blocked — content cannot be fetched
- Token budget too small for meaningful content — minimal output returned

## 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/html-to-markdown)

## Output

Returns a JSON object with a 'data' field containing the distilled Markdown, structured JSON, skeleton outline, or BM25 budget excerpt depending on mode. Also includes an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Optional 'cache' metadata indicates HIT/MISS status and latency. Billing details are included when payment is processed.
