> Web URL & HTML Distillation with BM25 Budget Control is a paid API for AI agents from json-repair.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a URL or raw HTML and distills it into compact, agent-ready tokens using markdown, structured, skeleton, or BM25-budget modes with strict token ceiling control.

## 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-html-distillation-with-bm25-budget-b732dbd8
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown using budget mode, focused on 'payment intents', and keep it under 500 tokens.

## When to prefer this

Choose this endpoint when you need to feed webpage content to an LLM but want to minimize token usage and cost — especially when you have a strict token budget or a specific BM25 keyword focus. It is ideal over raw web scraping when you need clean markdown or structured JSON output rather than raw HTML. Prefer it over generic summarization APIs when you need quantified ROI metrics (tokens saved, compression ratio) and support for multiple distillation modes including skeleton outlines and structured tables.

## Known failure modes

- Invalid or unreachable URL returns an error status
- mode=budget without a query or max_tokens may return unfiltered content
- Very large HTML payloads may exceed processing limits
- Paywalled or JavaScript-rendered pages may return incomplete distillation
- Missing required 'url' parameter returns a 400-level error
- x402 payment not fulfilled results in a 402 Payment Required response

## 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/api/diet)

## Output

Returns a JSON object with a 'data' field containing the distilled content (markdown, structured JSON, skeleton, or BM25 excerpt depending on mode), plus an 'roi_proof' object showing raw token count, distilled token count, tokens saved, compression ratio percentage, ROI multiplier, and estimated LLM cost saved in USD. Also includes optional cache hit/miss status and billing details.
