# Webpage Distiller – BM25 Budget-Controlled Web Content Extraction

> Webpage Distiller – BM25 Budget-Controlled Web Content Extraction is a paid API for AI agents from json-repair.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a URL or raw HTML and distills it into compact, agent-ready tokens using markdown, structured, skeleton, or BM25-budget modes with measurable token compression.

## 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 json-repair-agentdiet-dev-webpage-distiller-bm25-budget-controlled-dec2ddba
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 2000 tokens and focusing on the BM25 query 'payment intents'?

## When to prefer this

Choose this endpoint when you need to inject live web content into an LLM prompt but want to minimize token usage and cost — especially when the raw page would exceed your context window. It is superior to raw fetch-and-paste when token budget control matters, when you need BM25-focused relevance filtering on a specific query, or when you want structured JSON tables extracted from HTML rather than unformatted markup. It is also ideal when you need measurable compression ROI proof for cost accounting in agent pipelines.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML too large or malformed may produce incomplete distillation
- mode=budget without a query or max_tokens may fall back to default behavior
- Paywalled or JavaScript-heavy pages may yield minimal or empty content
- Payment failure (x402) if agent_id or USDC balance is insufficient
- Rate limiting if called too frequently without valid billing credentials

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://json-repair.agentdiet.dev/v1/webpage-distiller)

## Output

Returns a JSON object containing the distilled content (in the requested mode: markdown text, structured JSON tables/metadata, skeleton outline, or BM25-filtered excerpt), an ROI proof block showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD, plus optional billing and cache hit/miss metadata.
