# Web URL Distiller with BM25 Budget Control

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

Fetches and distills any webpage URL (or raw HTML) into compact, agent-ready tokens using configurable extraction modes including BM25-ranked 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 cve-intel-agentdiet-dev-web-url-distiller-with-bm25-budget-control-8e725f02
```

Example prompt: Can you fetch https://techcrunch.com/2024/01/15/openai-update and distill it into a focused excerpt about safety announcements, keeping it under 300 tokens using budget mode?

## When to prefer this

Choose this endpoint when your agent needs to read web pages without blowing through its token budget — especially when you want BM25-ranked excerpts focused on a specific query, or when you need structured/skeleton extraction rather than raw HTML parsing. Ideal for research agents, CVE monitoring pipelines, and any workflow that needs to ingest many URLs efficiently. Prefer this over generic scrapers when token compression ROI and cost savings metrics matter to your workflow.

## Known failure modes

- URL is unreachable or returns non-200 HTTP status — endpoint may return an error status
- URL points to non-HTML content (PDF, binary) that cannot be parsed — distillation may fail or return empty data
- max_tokens set below minimum of 20 — request rejected with validation error
- mode=budget used without providing a query — BM25 ranking has no focus signal
- Raw HTML provided via html parameter is malformed — distillation may produce incomplete output
- Rate limiting or payment failure via x402 — request blocked with 402 Payment Required

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://cve-intel.agentdiet.dev/v1/article-extractor)

## Output

Returns a JSON object with: a 'data' field containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode); an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd; optional 'cache' metadata (HIT/MISS, latency_ms); optional 'billing' metadata; and a 'status' field confirming execution.
