## 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 domain-osint-agentdiet-dev-web-content-distiller-with-bm25-budget-d4e5dfee -d '<json body>'
```

Example prompt: Distill this page — https://stripe.com/docs/payments — into clean markdown and keep it under 800 tokens, focused on the query 'payment intents API', using budget mode.

## When to prefer this

Choose this endpoint when you need to reduce LLM context costs by compressing web pages before feeding them to a language model, especially when you want BM25-ranked relevance filtering with a strict token budget. Prefer it over generic scrapers when you need both clean content extraction AND proof of token savings. Ideal for agentic pipelines that need to process many URLs efficiently without blowing token limits.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Token budget too small (below 20) returns a validation error
- HTML payload too large may cause timeout or truncation
- BM25 query with no matching content returns minimal excerpt
- Payment failure via x402 returns 402 Payment Required
- Rate limiting may occur for high-frequency calls without idempotency key

## How this service works

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

## Output

Returns a JSON object containing distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an ROI proof block showing raw vs. distilled token counts, tokens saved, compression ratio percentage, LLM cost saved in USD, and a ROI multiplier. Also includes cache status (HIT/MISS) and billing details.
