## 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-to-markdown-distiller-with-bm25-38a240a0
```

Example prompt: Fetch https://stripe.com/docs/api and distill it into compact markdown using budget mode with a 2000-token ceiling, focused on 'payment intents'.

## When to prefer this

Choose this endpoint when you need to feed live web content to an LLM but want to minimize token usage and cost — especially when the raw HTML is bloated with navigation, ads, or boilerplate. Ideal for agentic pipelines that need to read documentation, competitor pages, or news articles within strict token budgets. The BM25 budget mode is especially useful when you have a specific question and want only the most relevant passages. Prefer this over generic scrapers when you need both content extraction and token-cost optimization in a single call.

## Known failure modes

- Invalid or unreachable URL returns an error status
- max_tokens below minimum of 20 rejected with validation error
- BM25 query mode (budget) with no query string may return unfiltered excerpt
- Raw HTML too large may exceed processing limits
- Paywalled or JavaScript-heavy SPAs may return incomplete content
- x402 payment failure if agent lacks sufficient USDC balance

## 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/spa-markdown-reader)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown text, structured tables/metadata, skeleton outline, or BM25-ranked excerpt depending on mode), plus an 'roi_proof' object showing raw vs. distilled token counts, compression ratio, tokens saved, and estimated LLM cost savings. Optionally includes billing info and cache hit/miss status.
