# Web Content Distillation with BM25 Budget Control

> Web Content Distillation 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 compresses a URL or raw HTML into Markdown, structured JSON, skeleton outline, or a BM25-ranked token-budget excerpt optimized for LLM consumption.

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-web-content-distillation-with-bm25-budget-d0ecea1f -d '<json body>'
```

Example prompt: Fetch https://stripe.com/docs/payments and distill it into clean Markdown using budget mode, focusing on 'payment intents' and keeping it under 2000 tokens — I need to see how many tokens we're saving.

## When to prefer this

Choose this endpoint when you need to reduce token consumption from web pages or HTML before passing content to an LLM, especially when working with strict context windows or cost budgets. The BM25 budget mode is uniquely valuable when you have a specific query and want only the most relevant passages within a hard token ceiling. Prefer this over generic scrapers when you need built-in ROI proof (tokens saved, cost saved) and multiple distillation modes (Markdown, structured, skeleton, budget) in a single call priced at $0.001.

## Known failure modes

- URL is unreachable or returns non-200 — endpoint cannot fetch and will return an error status
- HTML payload is empty or malformed — distillation returns empty or minimal output
- max_tokens set too low (below 20) — rejected with validation error
- mode=budget used without a query — BM25 ranking has no focus signal, may return degraded results
- Payment not provided or fails — x402 payment required error before processing
- Rate limit or timeout on the target URL — fetch failure propagated in 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://token-intel.agentdiet.dev/v1/context-compress)

## Output

Returns a 'data' object containing the distilled content (Markdown text, structured JSON tables/metadata, skeleton outline, or BM25-ranked excerpt), plus an 'roi_proof' block showing raw_tokens, distilled_tokens, tokens_saved, compression_ratio_pct, roi_multiplier, and llm_cost_saved_usd. Also includes cache status (HIT/MISS) and billing details.
