## 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 company-enrich-agentdiet-dev-rag-token-diet-bm25-budget-controlled-6153568e -d '<json body>'
```

Example prompt: Distill the page at https://stripe.com/docs/payments into clean Markdown with a strict 1500-token budget, focused on the query 'how does payment intent work', using budget mode.

## When to prefer this

Choose this endpoint when you need to feed web content into an LLM but want to minimize token spend and noise. It is especially valuable in RAG workflows where you need BM25-ranked, query-focused excerpts under a strict token budget. Prefer it over generic scrapers when compression ratio and cost-savings proof matter, or when you need structured JSON tables and metadata rather than raw HTML dumps.

## Known failure modes

- URL is unreachable or returns non-200 — distillation cannot proceed
- HTML payload is empty or malformed — returns error status
- mode=budget with no query or max_tokens — BM25 ranking cannot be applied
- Target page is behind a login wall or CAPTCHA — content cannot be fetched
- Token budget too low (below 20) — rejected by schema validation
- Payment not authorized via x402 — 402 response before distillation begins

## How this service works

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

## Output

Returns a 'data' object containing the distilled content in the requested format (Markdown, structured JSON, skeleton, or BM25 excerpt), plus an 'roi_proof' block showing raw vs distilled token counts, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Optionally includes cache hit/miss status and billing details.
