## 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-url-token-optimizer-distiller-1ed73517
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 800 tokens focused on the query 'payment intents' using budget mode?

## When to prefer this

Choose this endpoint when your agent needs to read a webpage but must minimize token consumption before passing content to an LLM — especially when context windows are tight, LLM costs matter, or you need only a focused excerpt via BM25. It is preferable over raw web fetching because it handles fetching, cleaning, and compression in one step with quantified ROI proof. Use it over generic scrapers when you need structured output modes (markdown, JSON tables, skeleton, budget-capped excerpt) rather than raw HTML.

## Known failure modes

- Invalid or unreachable URL returns an error status
- HTML too large or malformed may yield poor distillation quality
- mode=budget without a query or max_tokens may fall back to defaults
- Payment failure (HTTP 402) if x402 micropayment not completed
- Cache miss on first fetch may increase latency
- Paywalled or JavaScript-rendered pages may return incomplete content

## 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/token-optimizer)

## Output

Returns a data object containing the distilled content (markdown, structured JSON tables/metadata, skeleton outline, or BM25-ranked budget excerpt), plus an roi_proof block showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and ROI multiplier. Also includes optional cache status (HIT/MISS) and billing details.
