## 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 polymarket-odds-agentdiet-dev-web-url-html-distiller-with-bm25-budget-4bf922b2
```

Example prompt: Can you distill https://stripe.com/docs/api into compact markdown and show me how many tokens were saved versus the raw page?

## When to prefer this

Choose this endpoint when you need to reduce a large webpage or HTML document to a token-efficient representation before passing it to an LLM, especially when you have a strict token budget. It is particularly valuable when you have a specific focus query and want BM25-ranked relevance filtering rather than naive truncation. Prefer it over generic scrapers when you need ROI metrics (tokens saved, compression ratio) as part of your agent's reasoning. Best suited for single-URL distillation with configurable output modes; not designed for bulk crawling or full-site indexing.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint may error or return empty content
- HTML payload too large for processing — may hit internal size limits
- mode=budget without a query parameter provided — BM25 ranking has no focus signal
- max_tokens set below meaningful threshold (minimum 20) — very sparse excerpts
- Payment failure via x402 — 402 response requiring USDC payment on Base before content is returned
- Rate limiting or bot-blocking by the target URL — distillation fails silently or returns partial 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://polymarket-odds.agentdiet.dev/v1/context-bloat-eliminator)

## Output

Returns a 'data' object containing the distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), along with an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Also includes optional cache status (HIT/MISS) and billing details.
