> Web URL Context Compressor (BM25 Budget Mode) is a paid API for AI agents from company-enrich.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a webpage or raw HTML and distills it into compact, agent-ready tokens using configurable modes including markdown, structured JSON, skeleton outline, or BM25-focused budget excerpts.

## 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 company-enrich-agentdiet-dev-web-url-context-compressor-bm25-budget-368d0ec5
```

Example prompt: Distill https://stripe.com/docs/payments into compact markdown, keeping it under 2000 tokens and focusing on 'payment intents' — I need it agent-ready without burning my context window.

## When to prefer this

Choose this endpoint when an AI agent needs to read web content but must stay within a strict token budget — especially for LLM pipelines where context window cost matters. Prefer over raw fetch tools when you need the output pre-formatted as markdown, structured JSON, or a skeleton outline. The BM25 budget mode is uniquely valuable when you want only the most query-relevant passages from a page, not the full document. Best for single-URL distillation with measurable token savings.

## Known failure modes

- Invalid or unreachable URL returns fetch error
- HTML too large may exceed processing limits
- BM25 budget mode without a query parameter may return unfiltered content
- max_tokens below minimum of 20 rejected with validation error
- Payment failure via x402 returns 402 status blocking the request
- Mode enum value outside allowed set returns parameter validation error

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://company-enrich.agentdiet.dev/v1/context-compress)

## Output

Returns a 'data' object containing the distilled content in the requested mode (markdown text, structured JSON tables/metadata, skeleton outline, or BM25 budget excerpt), plus ROI proof metrics including raw token count, distilled token count, tokens saved, compression ratio percentage, and estimated LLM cost saved in USD. Also includes cache status (HIT/MISS) and billing details.
