# AgentDiet Web Distiller with BM25 Budget Control

> AgentDiet Web Distiller with BM25 Budget Control is a paid API for AI agents from agentdiet.dev, paid per call via MPP, $0.001000/call, status unknown (last checked 2026-10-23).

Fetches and distills a URL or raw HTML into compressed Markdown, structured JSON, skeleton outlines, or BM25-ranked token-budget excerpts for LLM-efficient consumption

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 agentdiet-dev-agentdiet-web-distiller-with-bm25-budget-control-aad6a6bc -d '<json body>'
```

Example prompt: Fetch the page at https://stripe.com/docs/payments and distill it into markdown, keeping it under 2000 tokens — only the parts relevant to 'payment intents'.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost. It is especially valuable when you have a specific query and want BM25-ranked excerpts (mode=budget) rather than full-page dumps, or when you want structured JSON tables or skeleton outlines instead of raw HTML. Prefer it over generic scrapers when token ROI and compression ratio matter, or when you need a built-in proof of savings for billing optimization.

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status — endpoint returns an error status
- HTML payload is empty or malformed — distillation may return minimal or empty content
- max_tokens ceiling is set too low (below 20) — rejected by schema validation
- BM25 query is missing when mode=budget — may return unfiltered or fallback content
- Target site blocks automated fetching (bot protection) — fetch fails or returns incomplete HTML
- Token budget exceeded by raw content before distillation — output may be truncated

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured tables, skeleton outline, or BM25 excerpt depending on mode), plus an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, and llm_cost_saved_usd, along with cache status and billing details.
