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 defi-yield-agentdiet-dev-web-distillation-with-bm25-budget-control-2b229ddf -d '<json body>'
```

Example prompt: Can you fetch the Stripe pricing page at https://stripe.com/pricing and distill it into clean Markdown, keeping it under 1000 tokens using budget mode with the query 'pricing tiers'?

## When to prefer this

Choose this endpoint when you need to ingest web content into an LLM prompt and want to minimize token consumption via compression or BM25-ranked excerpting. Ideal for documentation ingestion, RAG pipelines, and any scenario where raw HTML is too verbose. Prefer over generic scrapers when you need built-in token budgeting, ROI reporting, or structured/skeleton output modes rather than raw HTML or unprocessed text.

## Known failure modes

- URL is unreachable or returns non-200 status — endpoint may return an error status
- Raw HTML is malformed and cannot be parsed — distillation may produce empty or degraded output
- max_tokens set too low (below 20) — rejected by schema validation
- mode=budget requested without a query parameter — BM25 ranking has no focus term
- Target page blocks scraping via robots.txt or CAPTCHA — fetch fails
- Payment not provided or insufficient — HTTP 402 returned

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the distilled output (Markdown text, structured JSON, skeleton outline, or BM25-ranked excerpt depending on mode), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes optional cache hit/miss status and billing metadata.
