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 token-intel-agentdiet-dev-web-content-distiller-with-bm25-budget-37ceec4b -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/payments and distill it in budget mode focused on the query 'payment intents API' with a max of 1500 tokens, so I can pass just the relevant section into my prompt.

## When to prefer this

Choose this endpoint when you need to inject web content into an LLM prompt but must control token spend — especially in RAG pipelines, agent research loops, or summarization chains. The BM25 budget mode is uniquely suited for pulling only the most topically relevant passages from long documents when you have a specific query. Prefer this over generic scraping tools when token efficiency and LLM cost reduction are priorities.

## Known failure modes

- URL is unreachable or returns non-200 — fetch failure with error status
- max_tokens set below 20 — validation error
- mode=budget used without a query field — may return unranked or degraded output
- Raw HTML too large to process within limits — truncation or timeout
- Payment not completed — HTTP 402 returned, endpoint requires x402 payment
- Invalid URL format — schema validation error

## How this service works

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

## Output

Returns a distilled representation of the webpage or HTML in the chosen mode (markdown, structured JSON, skeleton outline, or BM25 budget excerpt), along with ROI proof metrics showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
