# Web URL & HTML Distillation with BM25 Budget Control

> 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 accepts raw HTML and distills it into compact, agent-ready tokens using markdown, structured, skeleton, or BM25-focused budget modes

## 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-f80b20bd
```

Example prompt: Can you distill https://stripe.com/docs/payments into compact markdown, using budget mode focused on 'payment intents' and keeping it under 500 tokens?

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM and want to minimize token consumption with measurable ROI metrics. It is especially valuable when you have a strict token budget (use mode=budget with a query and max_tokens), need structured table/metadata extraction from HTML (mode=structured), or want a fast outline of page structure (mode=skeleton). Prefer it over generic scrapers when you need built-in BM25 relevance filtering, compression ratio reporting, and LLM cost savings quantification. It also accepts raw HTML directly, making it useful when you already have scraped content and just need distillation without an extra fetch.

## Known failure modes

- URL unreachable or returns non-200 status — endpoint cannot fetch content
- HTML payload too large for processing within token constraints
- Invalid mode enum value provided — falls back to markdown or returns error
- max_tokens set below minimum of 20 — validation error returned
- BM25 query provided without mode=budget — query may be silently ignored
- Payment not completed (HTTP 402) — response blocked until x402 payment fulfilled
- Malformed URL string that fails minLength or format validation

## 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/clean-html)

## Output

Returns a 'data' object containing distilled content (markdown text, structured JSON tables/metadata, skeleton outline, or BM25-focused excerpt depending on mode), alongside 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 cache status (HIT/MISS) and billing details.
