## 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 shopify-intel-agentdiet-dev-web-url-context-distiller-bm25-budget-5759a507
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown, using budget mode focused on 'payment intents' with a strict ceiling of 500 tokens, so I can feed just the relevant content to my LLM without blowing my context window.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token consumption and cost. It is especially valuable when the source page is long, noisy, or filled with boilerplate, and you only need semantically relevant excerpts (use mode=budget with a BM25 query). Prefer it over raw scraping when your pipeline has a strict token budget or when you want structured extraction (tables, metadata) rather than raw HTML.

## Known failure modes

- Invalid or unreachable URL returns fetch error
- HTML too large or malformed may produce incomplete distillation
- mode=budget without a query or max_tokens may fall back to default behavior
- Rate limiting or payment failure (402) blocks the call
- Paywalled or JavaScript-heavy pages may return sparse content
- builtin:// scheme only works for recognized built-in doc targets like stripe-docs

## How this service works

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

## Output

Returns a distilled payload (markdown, structured JSON tables/metadata, skeleton outline, or BM25-ranked budget excerpt) along with ROI proof metrics including raw vs. distilled token counts, compression ratio percentage, tokens saved, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing details.
