# Web URL Distillation to Compact Agent-Ready Tokens

> Web URL Distillation to Compact Agent-Ready Tokens 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 web URL (or accepts raw HTML) and distills it into compact, token-efficient markdown, structured JSON, skeleton outline, or BM25-ranked budget excerpt for AI agent 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 onchain-risk-agentdiet-dev-web-url-distillation-to-compact-agent-ec885c9e
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 800 tokens using budget mode with a focus query on 'payment intents'?

## When to prefer this

Choose this endpoint when an AI agent needs to ingest web page content without blowing its context window — especially when token cost control is critical. The BM25 budget mode is uniquely suited for focused retrieval within strict token ceilings, making it superior to generic scrapers when LLM cost efficiency matters. Prefer this over raw HTML fetch tools when you need compression metrics and proof of token savings. The structured and skeleton modes are ideal when downstream agents need parseable JSON or a quick outline rather than full prose.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- URL produces no extractable text content (e.g. pure JavaScript SPA with no SSR) — distilled output may be empty or minimal
- max_tokens set too low (below 20) — request rejected by schema validation
- BM25 query provided without mode=budget — query may be ignored
- Raw HTML too large — may exceed processing limits
- Payment failure via x402 — 402 response if USDC payment not completed
- Invalid URL format — schema validation error on minLength/format

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://onchain-risk.agentdiet.dev/v1/web-scrape)

## Output

Returns a JSON object containing: distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt depending on mode), cache hit/miss status and latency, billing details, and an roi_proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD.
