## 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 cve-intel-agentdiet-dev-semantic-html-pruner-with-bm25-budget-control-c7be9ae3 -d '<json body>'
```

Example prompt: Can you distill https://stripe.com/docs/payments into clean markdown using budget mode, focused on 'payment intents', and keep it under 2000 tokens?

## When to prefer this

Choose this endpoint when you need to reduce LLM token consumption by compressing live web content or raw HTML before feeding it into a language model. It is especially valuable when you have a specific query focus and want BM25-ranked pruning to extract only the most relevant content within a strict token ceiling. Prefer it over generic scraping tools when you need provable token savings with ROI metrics.

## Known failure modes

- URL is unreachable or returns non-200 — fetch failure error
- Invalid or empty HTML provided when using html parameter — parsing error
- Token budget too small (below 20) to produce meaningful output
- BM25 query missing when mode=budget — validation error
- Timeout fetching large or slow-loading pages
- Payment not completed via x402 — 402 Payment Required response

## How this service works

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

## Output

Returns a data object containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), plus ROI proof fields showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing info.
