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 whale-momentum-agentdiet-dev-markdown-distill-with-bm25-budget-control-1d53db00 -d '<json body>'
```

Example prompt: Can you fetch https://docs.stripe.com/api and distill it into clean markdown, keeping it under 2000 tokens and focusing on 'authentication' using BM25 budget mode?

## When to prefer this

Choose this endpoint when you need to reduce token consumption before sending web content to an LLM, especially when working with long documentation pages, product catalogs, or research articles. The BM25 budget mode is uniquely suited for query-focused extraction with a hard token ceiling — ideal for RAG pipelines, agent memory, or cost-sensitive LLM workflows. Prefer it over generic scrapers when you need both content cleaning and token-budget enforcement in one step.

## Known failure modes

- URL unreachable or returns non-200 — fetch fails with error status
- HTML payload too large or malformed — parser error returned
- max_tokens below minimum of 20 — validation error
- query missing when mode=budget — BM25 ranking cannot proceed
- Payment not included or insufficient — HTTP 402 returned
- Rate limit exceeded — request throttled

## How this service works

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

## Output

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