# Web URL DOM Distiller with BM25 Budget Control

> Web URL DOM Distiller with BM25 Budget Control is a paid API for AI agents from serp-extract.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a webpage URL (or accepts raw HTML) and distills it into compact, agent-ready tokens using configurable modes including BM25-focused budget excerpts

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 serp-extract-agentdiet-dev-web-url-dom-distiller-with-bm25-budget-ca741f93
```

Example prompt: Grab the content from https://docs.stripe.com/payments/payment-intents and distill it into clean markdown, keeping it under 2000 tokens and focused on the query 'payment intent lifecycle'.

## When to prefer this

Choose this endpoint when you need to read a webpage inside a token-constrained LLM context and want automatic compression with ROI reporting. It is especially valuable when you need BM25-focused excerption (only the parts of the page matching a query), structured extraction of tables/metadata, or when you want to minimize LLM inference costs by reducing input token count before passing content to a model.

## Known failure modes

- Invalid or unreachable URL returns an error status
- max_tokens set below 20 is rejected by schema validation
- BM25 query mode without a query string may return unfiltered content
- Paywalled or JavaScript-heavy pages may yield incomplete distillation
- Rate limits or payment failures (x402) block the request

## How this service works

Distill a web URL into compact agent-ready tokens (Live x402 v2, IETF MPP & MCP endpoint at https://serp-extract.agentdiet.dev/v1/dom-stripper)

## Output

Returns a 'data' object containing distilled content (Markdown, structured JSON, skeleton outline, or BM25-excerpted text depending on mode), plus an roi_proof block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
