## 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 agentdiet-dev-agentdiet-web-url-distiller-context-bloat-eliminator-667ce414
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, keeping it under 500 tokens and focused on the query 'payment intents'?

## When to prefer this

Choose this endpoint when your agent needs to read web pages or HTML but wants to minimize token consumption and LLM costs. It is especially valuable when you need to fit web content into a strict context window, when you want only the most query-relevant passages (BM25 budget mode), or when you need structured extraction of tables and metadata rather than raw page content. Prefer it over raw HTTP fetching whenever token efficiency matters.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status
- Raw HTML is malformed or empty
- max_tokens value is below minimum of 20
- mode=budget used without a query parameter
- Target page is behind authentication or CAPTCHA and cannot be fetched
- Payment not authorized (HTTP 402)
- Token budget too small to return meaningful content

## How this service works

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

## Output

Returns a distilled version of the page in the requested format (Markdown, structured JSON, skeleton outline, or BM25 budget excerpt), along with ROI proof metrics (raw tokens, distilled tokens, tokens saved, compression ratio, LLM cost saved in USD), cache status, and billing details.
