> Web URL Token Optimizer & Distiller is a paid API for AI agents from x402-audit.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a URL or raw HTML and distills it 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 x402-audit-agentdiet-dev-web-url-token-optimizer-distiller-6b95a32f
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown and keep it under 2000 tokens, focusing on the query 'payment intents API'?

## When to prefer this

Choose this endpoint when you need to feed webpage content into an LLM context window but want to minimize token usage and cost. It is especially valuable when working with long documentation pages, articles, or HTML dumps where only a portion is relevant. Prefer it over raw web scraping when you need BM25-ranked relevance filtering (budget mode with a query), structured JSON extraction, or a skeleton outline rather than full page text. It provides built-in ROI proof showing exactly how many tokens and dollars were saved.

## Known failure modes

- URL unreachable or returns non-200 status — fetch failure error
- Invalid or malformed URL provided — validation error
- max_tokens too low (below 20) — schema validation rejection
- mode=budget used without providing a query parameter — incomplete request
- Raw HTML too large to process within timeout — processing error
- Target site blocks automated fetching (bot protection) — access denied

## How this service works

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

## Output

Returns a JSON object with distilled content (markdown, structured tables, skeleton, or BM25 excerpt), ROI proof metrics (raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, llm_cost_saved_usd, roi_multiplier), optional cache hit/miss info, and billing details. The data field contains the actual distilled output in the requested format.
