# Web URL Distiller – Compact Agent-Ready Token Extraction

> Web URL Distiller – Compact Agent-Ready Token Extraction is a paid API for AI agents from onchain-risk.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a target webpage and distills it into compact, token-efficient representations (markdown, structured JSON, skeleton outline, or BM25-focused budget excerpt) for LLM/agent consumption.

## 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 onchain-risk-agentdiet-dev-web-url-distiller-compact-agent-ready-578de775
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown — I want the token-efficient version so I can feed it to my LLM without blowing my context window.

## When to prefer this

Choose this endpoint when an AI agent needs to ingest a live webpage but wants to minimize LLM token consumption and cost. It is especially useful when the raw HTML would exceed context limits, when only a structural outline or targeted excerpt is needed, or when you want to feed structured tables/metadata rather than raw HTML to a downstream model. Prefer the budget+query mode when you have a specific question about the page content.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Paywalled or bot-blocked pages may return incomplete or empty content
- mode=budget without a query parameter may produce suboptimal excerpts
- max_tokens set too low may truncate meaningful content
- Payment failure via x402 prevents the call from completing
- Timeout on slow or large pages may result in partial distillation

## How this service works

Distill a web URL into compact agent-ready tokens (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/webpage-distiller)

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt), an ROI proof block showing raw vs. distilled token counts, compression ratio, and estimated LLM cost saved, plus optional cache hit/miss status and billing details.
