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 mesh-agentdiet-dev-web-content-distiller-with-bm25-budget-control-7658ca33 -d '<json body>'
```

Example prompt: Can you distill https://stripe.com/docs/payments into clean markdown, keeping it under 2000 tokens and focusing on the topic 'payment intents' using BM25 budget mode?

## When to prefer this

Choose this endpoint when you need to reduce token consumption before inserting web content into an LLM prompt, especially when you have a strict token budget or want BM25-ranked relevance filtering. It is ideal for agentic workflows that repeatedly fetch and process web pages, where saving LLM context cost is critical. Prefer over generic scrapers when you need built-in compression metrics, structured output modes, or raw HTML passthrough without an external fetch.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML payload too large may exceed processing limits
- BM25 budget mode requires both 'query' and 'max_tokens' to be meaningful
- max_tokens set below 20 is rejected by schema validation
- Payment failure via x402 blocks execution
- Rate limiting or bot-blocking on target URL prevents fetching

## How this service works

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

## Output

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