> Web Distillation with BM25 Budget Control is a paid API for AI agents from domain-osint.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches a URL or accepts raw HTML and distills it into clean Markdown, structured JSON, skeleton outline, or a BM25-ranked token-budgeted excerpt

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 domain-osint-agentdiet-dev-web-distillation-with-bm25-budget-control-53eca6e8 -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/payments and distill it into clean markdown with a 2000-token budget, focused on the query 'payment intents', so I can feed just the relevant parts to my LLM.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM and want to minimize token usage through intelligent compression. It is especially useful when you have a specific query and want BM25-ranked excerpts rather than full-page content, or when you need structured JSON tables or a skeleton outline instead of raw HTML. Prefer it over generic scrapers when token cost reduction and ROI metrics matter.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML too large may exceed processing limits
- BM25 budget mode requires both 'query' and 'max_tokens' to produce meaningful results
- Missing required 'url' field returns a validation error
- Rate limiting or payment failure via x402 may block the request

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://domain-osint.agentdiet.dev/v1/docs-to-markdown)

## Output

Returns a JSON object with a 'data' field containing the distilled output (Markdown, structured JSON, skeleton, or BM25 excerpt), plus an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
