# AgentDiet Web URL Distiller

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

Fetches a URL or raw HTML and compresses it into compact, agent-ready tokens using BM25 budget control and multiple distillation 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 mcp-compiler-agentdiet-dev-agentdiet-web-url-distiller-e940d371
```

Example prompt: Grab the Stripe docs page at https://stripe.com/docs/payments and distill it into compact markdown — use budget mode with the query 'payment intents' and cap it at 500 tokens so I don't blow my context window.

## When to prefer this

Choose this endpoint when an AI agent needs to consume web content without exhausting its context window — especially for documentation pages, news articles, or data-heavy HTML. It is ideal when token cost is a concern and you want measurable compression ratios. Prefer it over generic scrapers when you need multiple distillation modes (markdown, structured, skeleton, budget) or BM25 query-focused extraction. The built-in ROI proof makes it easy to justify token savings in agentic pipelines.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML fetch timeout for slow or blocked domains
- max_tokens set below minimum of 20 causes validation error
- BM25 query missing when mode=budget may return unranked content
- Payment/402 failure if x402 micropayment not resolved
- Raw HTML too large may be truncated or rejected

## How this service works

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

## Output

Returns a JSON object containing distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked budget excerpt depending on mode), along with an ROI proof block showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved. Also includes cache status (HIT/MISS) and billing details.
