## 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-distillation-with-bm25-budget-control-079ac2a2 -d '<json body>'
```

Example prompt: Distill https://stripe.com/docs/payments into markdown mode and tell me how many tokens you saved compared to the raw page.

## When to prefer this

Choose this endpoint when you need to compress a webpage or raw HTML into a token-efficient form before feeding it to an LLM, especially when you want BM25-focused budget excerpts that surface only query-relevant content within a strict token ceiling. It is ideal for agents that need to read documentation, news articles, or data pages without blowing up context windows or LLM costs. Prefer it over generic scraping tools when token savings metrics and cost ROI reporting are needed alongside the content.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint may return an error status
- Raw HTML provided is malformed or empty — distillation may produce minimal output
- mode=budget used without a query parameter — BM25 focus cannot be applied
- max_tokens set below 20 — rejected by schema validation
- Paywalled or JavaScript-rendered pages may yield incomplete content
- Payment via x402 fails — call is not executed

## 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/distill)

## Output

Returns a data object containing the distilled content (Markdown string, structured JSON tables/metadata, skeleton outline, or BM25-filtered excerpt), plus an roi_proof block showing raw token count, distilled token count, tokens saved, compression ratio percentage, estimated LLM cost saved in USD, and ROI multiplier. Also includes optional cache hit/miss status and billing details.
