> Web URL Distiller with BM25 Budget Control is a paid API for AI agents from x402broker.com, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a webpage URL (or processes raw HTML) and distills it into compact, agent-ready tokens with configurable modes including markdown, structured JSON, skeleton outline, or BM25-focused budget excerpts

## 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 x402broker-com-web-url-distiller-with-bm25-budget-control-6322fc8e
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, keeping it under 2000 tokens using budget mode focused on the query 'payment intents'?

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token consumption and cost. It is ideal when the source page is long or noisy and you only need the semantically relevant portion (use budget+query mode), or when you want structured tables and metadata rather than raw HTML. Prefer it over generic scrapers when you care about token ROI and need a ready-to-use compressed representation rather than raw page content.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Token budget too small (max_tokens below 20) causes validation failure
- BM25 query mode used without providing a 'query' parameter may return unfiltered content
- Rate limiting or payment failure via x402 causes request rejection
- Raw HTML input is malformed or empty, resulting in empty distilled output
- Target page blocks automated fetching (e.g. bot detection, CAPTCHA walls)

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/pdf-extract)

## Output

Returns a 'data' object containing the distilled content (markdown text, structured tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), along with an roi_proof block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing metadata.
