# AgentDiet Web Distillation API

> AgentDiet Web Distillation API is a paid API for AI agents from agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches and compresses a web page or raw HTML into compact, agent-ready tokens using BM25 budget control and multiple 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 agentdiet-dev-agentdiet-web-distillation-api-640e00c8
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown and keep it under 800 tokens, focusing on the query 'payment intents' using budget mode.

## When to prefer this

Choose this endpoint when your agent needs to read web content but must operate within a token budget — especially for LLM pipelines where raw HTML or verbose pages would be too expensive to process. Prefer it over generic scrapers when you need BM25-ranked excerpts, structured table extraction, or skeleton outlines rather than raw HTML dumps. Best suited for agents doing research, RAG enrichment, or competitive intelligence on live web pages.

## Known failure modes

- Invalid or unreachable URL returns fetch error
- URL blocked by robots.txt or anti-bot protections
- max_tokens below minimum of 20 returns validation error
- mode=budget without a query may return unfiltered or empty excerpt
- Payment failure via x402 returns 402 with payment details
- HTML too large for processing may be truncated or rejected
- Malformed HTML input may produce incomplete distillation

## 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/v1/web-scrape)

## Output

Returns a 'data' object containing distilled content in the chosen format (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' object showing raw vs. distilled token counts, tokens saved, compression ratio percentage, LLM cost saved in USD, and ROI multiplier. Also includes optional cache status (HIT/MISS) and billing details.
