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 agentdiet-dev-agentdiet-web-distillation-with-bm25-budget-control-5028e280 -d '<json body>'
```

Example prompt: Fetch the Stripe documentation page at https://stripe.com/docs/payments and distill it in budget mode focused on 'payment intents', keeping it under 500 tokens, so I can feed it to my LLM without blowing my context window.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost. It's especially valuable when working with long documentation pages, news articles, or any raw HTML where only a subset is relevant to a specific query. The BM25 budget mode makes it uniquely suited for RAG pipelines where you need a focused, token-capped excerpt. Prefer this over generic scrapers when you need built-in compression metrics and LLM cost accounting.

## Known failure modes

- URL is unreachable or returns non-200 status — distillation fails with an error status
- Raw HTML is malformed and cannot be parsed — returns empty or partial data
- max_tokens is set too low to return meaningful content — truncated or empty excerpt
- BM25 query finds no relevant sections — returns minimal or empty budget excerpt
- Rate limiting or payment failure via x402 — request rejected before processing
- URL is blocked by robots.txt or requires authentication — fetch fails

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/a2a)

## Output

Returns a 'data' object containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' object with raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
