# Webpage Distiller with BM25 Budget Control

> Webpage 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 and distills a URL or raw HTML into compressed Markdown, structured JSON, a skeleton outline, or a BM25-ranked token-budgeted excerpt

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-webpage-distiller-with-bm25-budget-control-1de00897 -d '<json body>'
```

Example prompt: Distill the content at https://openai.com/research/gpt-4 into clean markdown using BM25 budget mode, focusing on 'model capabilities and benchmarks', and keep it under 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM and want to minimize token consumption — especially in budget mode with BM25 query ranking to extract only the most relevant content. Prefer it over raw fetch+parse pipelines when you need built-in compression metrics, ROI proof, and token ceiling enforcement. It is particularly valuable for agents that need to process many pages cheaply or need to stay within context window limits.

## Known failure modes

- Invalid or unreachable URL returns a fetch error
- HTML too large to process within budget may return truncated output
- mode='budget' without a 'query' parameter may return unranked content
- max_tokens set too low (< 20) is rejected by schema validation
- Paywalled or JS-rendered pages may return incomplete distillation
- Payment failure via x402 returns HTTP 402 with payment details

## 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/webpage-distiller)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), an ROI proof object showing raw vs distilled token counts, compression ratio, and estimated LLM cost savings, plus optional billing and cache metadata.
