## 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 polymarket-odds-agentdiet-dev-web-url-distiller-with-bm25-budget-1d4f6aeb
```

Example prompt: Distill the URL https://stripe.com/docs/payments/accept-a-payment into compact markdown using budget mode, focused on the query 'payment intent setup', with a max of 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM context window efficiently, especially when token costs matter. It excels over plain scraping when you need BM25-focused relevance trimming (budget mode), structured table extraction, or skeleton outlines. Prefer it over generic scrapers when you need built-in ROI metrics showing compression gains. Ideal for RAG pipelines, agent research tasks, and any workflow where raw HTML would be too token-expensive to process directly.

## Known failure modes

- Invalid or unreachable URL returns a fetch error
- max_tokens below minimum of 20 is rejected
- mode=budget without a query may produce unoptimized results
- Raw HTML input ignored if URL is also supplied and conflicts
- Rate limiting or payment failure via x402 returns 402 status
- Paywalled or JavaScript-heavy pages may yield incomplete distillation

## How this service works

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

## Output

Returns a distilled representation of the webpage (markdown, structured JSON, skeleton, or BM25 budget excerpt) alongside ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache status and billing details.
