## 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 agentdiet-dev-agentdiet-web-distillation-with-bm25-budget-control-738ac386 -d '<json body>'
```

Example prompt: Distill https://stripe.com/docs/payments/accept-a-payment into Markdown using budget mode, focused on 'payment intent API', keeping it under 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost — especially when the target page is long, noisy, or ad-heavy. The BM25 budget mode is uniquely suited for precision extraction when you only care about a specific topic within a large document. Prefer it over raw HTTP fetching whenever token efficiency matters, or when you need structured JSON tables extracted from HTML rather than raw text.

## Known failure modes

- URL unreachable or returns non-200 status — endpoint may return an error status
- HTML payload too large or malformed — distillation may fail or produce incomplete output
- mode=budget with no query or max_tokens — BM25 filtering cannot execute without focus parameters
- Invalid or expired payment — x402 payment required before content is returned
- max_tokens set below 20 — rejected by schema validation
- Idempotency key reused with different parameters — may return cached prior result

## How this service works

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

## Output

Returns a 'data' object containing the distilled content (Markdown text, structured JSON tables/metadata, 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, ROI multiplier, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
