## 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 json-repair-agentdiet-dev-web-url-distiller-bm25-budget-extractor-25790302
```

Example prompt: Fetch the page at https://stripe.com/docs/payments and distill it into clean markdown, keeping it under 500 tokens using budget mode focused on 'payment intents'.

## When to prefer this

Choose this endpoint when your agent needs to read web pages while controlling token costs — especially in budget mode with a keyword query and max_tokens ceiling. It is ideal for RAG pipelines, research agents, and any workflow where raw webpage HTML would otherwise blow a context window. Prefer it over general-purpose scrapers when you need BM25-focused excerpts or token-efficient markdown distillation with provable ROI metrics. The structured and skeleton modes are particularly useful when you want JSON tables or a navigable outline rather than full prose.

## Known failure modes

- Invalid or unreachable URL returns an error status
- max_tokens below minimum of 20 causes validation failure
- BM25 query parameter ignored when mode is not 'budget'
- Paywalled or bot-blocked pages may return incomplete content
- Raw HTML too large may be rejected or truncated
- Network timeout for slow remote pages
- Missing required 'url' parameter returns 400-level error

## How this service works

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

## Output

Returns a status field, distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), cache hit/miss info with latency, billing details, and an ROI proof object showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and ROI multiplier.
