## 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 alpha-stream-agentdiet-dev-agentdiet-web-distiller-with-bm25-budget-d95bc467 -d '<json body>'
```

Example prompt: Distill https://stripe.com/docs/payments into clean markdown with a 500-token budget focused on the query 'payment intents API' so I can fit it into my context window.

## When to prefer this

Choose this endpoint when you need to shrink web pages or HTML blobs into LLM-consumable tokens while maintaining semantic relevance — especially when operating under strict context window constraints. The BM25 budget mode is uniquely valuable when you want to focus distillation on a specific topic query rather than generic summarization. Prefer over generic scrapers when you need token savings proof and cost metrics alongside the content.

## Known failure modes

- URL unreachable or returns non-200 — fetch failure with error status
- HTML too short or empty — minimal or empty distillation output
- max_tokens below minimum of 20 — validation error
- BM25 query missing when mode=budget — may default or return error
- Rate limiting or payment failure via x402 — 402 Payment Required response
- Invalid URL format — schema validation rejection

## How this service works

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

## Output

Returns a distilled representation of the webpage or HTML in the requested mode (Markdown, structured JSON, skeleton, or BM25 budget excerpt), along with ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and optionally cache hit/miss status and billing details.
