# Context Bloat Eliminator – URL & HTML Distiller with BM25 Budget Control

> Context Bloat Eliminator – URL & HTML Distiller with BM25 Budget Control is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches a URL or accepts raw HTML and distills it into clean markdown, structured JSON, a skeleton outline, or a BM25-ranked token-budgeted excerpt for LLM context efficiency

## 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 whale-momentum-agentdiet-dev-context-bloat-eliminator-url-html-24dc188c -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/payments/checkout and distill it into clean markdown using BM25 budget mode, focused on 'payment intents', with a max of 500 tokens — I need a lean version for my LLM context window.

## When to prefer this

Choose this endpoint when you need to shrink a webpage or raw HTML payload before passing it to an LLM, especially when token costs or context window limits are a concern. It is uniquely suited for agentic pipelines where a web page must be fetched and condensed in a single step, with BM25 relevance ranking to focus the output on a specific query — something generic scrapers or markdown converters do not offer. Prefer it over raw fetch+parse approaches when you need ROI metrics (tokens saved, cost saved) or when you need structured JSON table extraction or skeleton outlines in addition to plain markdown.

## Known failure modes

- URL unreachable or returns non-200 — fetch failure with error status
- HTML too small or already minimal — low compression ratio, roi_multiplier near 1
- BM25 query provided without mode=budget — query may be ignored
- max_tokens set below content minimum — truncation may lose critical content
- Invalid URL format — schema validation error on 'url' field
- Payment/402 failure if x402 USDC payment not attached — billing error

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an 'roi_proof' block showing raw vs distilled token counts, compression ratio percentage, tokens saved, estimated LLM cost saved in USD, and a cache status object indicating HIT/MISS and latency.
