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 workflows-agentdiet-dev-agentdiet-rag-token-diet-web-url-distiller-072a71dc
```

Example prompt: Fetch https://stripe.com/docs/payments and distill it into compact markdown using budget mode with a max of 500 tokens, focused on the query 'payment intents'.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM context window efficiently and cheaply — especially when the raw page is too large, when you want BM25-focused excerpts around a specific query, or when you need ROI proof on token compression. Prefer over generic scrapers when token budget control and compression metrics matter, or when you need structured/skeleton output rather than raw HTML.

## Known failure modes

- Invalid or unreachable URL returns an error status
- mode=budget without a query or max_tokens may produce unconstrained output
- Raw HTML too large may exceed processing limits
- Paywalled or JavaScript-rendered pages may return incomplete distillation
- Missing required 'url' parameter returns a validation error
- x402 payment failure or insufficient funds blocks execution

## How this service works

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

## Output

Returns a distilled version of the webpage in the requested format (Markdown, structured JSON, skeleton outline, or BM25 budget excerpt), along with ROI proof metadata including raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and a billing summary. Cache hit/miss status and latency are also included.
