# Semantic HTML Pruner with BM25 Budget Control

> Semantic HTML Pruner with BM25 Budget Control is a paid API for AI agents from token-intel.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-23).

Fetches and distills a URL or raw HTML into compact Markdown, structured JSON, skeleton outline, or BM25-ranked token-budget excerpt to minimize LLM token costs

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 token-intel-agentdiet-dev-semantic-html-pruner-with-bm25-budget-control-7816a988 -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/payments/accept-a-payment and distill it into compact Markdown using budget mode focused on 'accept payment integration', keeping it under 2000 tokens.

## When to prefer this

Use this endpoint when you need to feed webpage content to an LLM but want to minimize token consumption and cost. It is especially valuable when working with long documentation pages, news articles, or structured web pages where you only need a relevant excerpt. Prefer the budget+BM25 mode when you have a specific query and a strict token ceiling. Prefer structured mode when you need tabular data extracted. Unlike generic scrapers, this endpoint provides built-in ROI proof showing exactly how many tokens and dollars were saved.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint may return an error status
- HTML payload is empty or malformed — distillation may return minimal or no content
- token budget too low (below 20) — rejected by schema validation
- BM25 query missing when mode=budget — may fall back to default behavior or error
- Rate limiting or payment failure via x402 — 402 response requiring payment
- Target page blocks scraping (bot detection) — may return incomplete or empty content

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://token-intel.agentdiet.dev/v1/semantic-html-pruner)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON, skeleton, or BM25 excerpt), an 'roi_proof' object showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd, plus optional cache status and billing details.
