# Web URL Distillation to Compact Agent-Ready Tokens

> Web URL Distillation to Compact Agent-Ready Tokens is a paid API for AI agents from x402broker.com, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a webpage (or processes raw HTML) and distills it into compact, token-efficient Markdown, structured JSON, outline skeleton, or BM25-focused budget excerpt for AI 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 x402broker-com-web-url-distillation-to-compact-agent-ready-tokens-ba2fc6b8
```

Example prompt: Grab the content from https://stripe.com/docs/payments and distill it into budget mode focused on the query 'webhook events' with a max of 500 tokens, so I can fit it into my context window.

## When to prefer this

Choose this endpoint when an AI agent needs to read web content but must stay within a strict token budget — especially for LLM pipelines where context window cost matters. Prefer over generic scrapers when you need built-in BM25 relevance filtering, multi-mode output (Markdown, structured, skeleton, budget), and token savings metrics. Ideal for RAG ingestion, competitor research, documentation lookup, and any workflow that needs clean, boilerplate-free web content at minimal token cost.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Paywalled or bot-blocked pages may return incomplete or empty content
- max_tokens too low for meaningful extraction may truncate all content
- query field required but missing when mode=budget
- Raw HTML too large may hit processing limits
- Payment/402 authentication failure prevents endpoint access

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://x402broker.com/v1/paywall-clean-extract)

## Output

Returns a status field, distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-filtered excerpt depending on mode), ROI proof metrics (raw vs distilled token counts, tokens saved, compression ratio, estimated LLM cost saved), optional cache hit/miss info, and billing details showing the fee charged.
