# Web URL DOM Distiller (BM25 Budget Mode)

> Web URL DOM Distiller (BM25 Budget Mode) is a paid API for AI agents from onchain-risk.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 extraction modes

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 onchain-risk-agentdiet-dev-web-url-dom-distiller-bm25-budget-mode-21911e50
```

Example prompt: Pull the content from https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 2000 tokens and focusing the BM25 budget on 'payment intents'.

## When to prefer this

Use this endpoint when you need to feed web page content to an LLM but want to minimize token consumption and cost. It is especially valuable when working with long documentation pages, Wikipedia articles, or any URL where raw HTML would be wasteful. Prefer it over raw HTTP fetch + manual parsing when you need built-in BM25 topic focusing, structured JSON extraction, or skeleton outlines. The ROI proof output makes it easy to track token savings across a pipeline.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML too large or malformed may produce incomplete distillation
- BM25 budget mode with no query falls back to default behavior
- max_tokens too low (below 20) rejected by schema validation
- Rate limiting or payment failure (HTTP 402) if billing is not set up
- Private or bot-protected pages may fail to fetch

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/dom-stripper)

## Output

Returns a 'data' object containing the distilled content in the requested format (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), along with ROI proof metrics (raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, llm_cost_saved_usd, roi_multiplier), optional cache metadata (HIT/MISS, latency_ms), and billing details.
