> Web URL Distiller & Context Trimmer is a paid API for AI agents from mesh.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches a webpage or raw HTML and compresses it into compact, agent-ready tokens using BM25 budget control and multiple distillation modes

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 mesh-agentdiet-dev-web-url-distiller-context-trimmer-d3ce3672
```

Example prompt: Distill the content at https://stripe.com/docs/payments into compact markdown, keeping it under 2000 tokens and focusing on the query 'payment intents API' using budget mode.

## When to prefer this

Choose this endpoint when you need to feed web content to an LLM but want to minimize token usage and cost. It is especially valuable when the target page is large or bloated with HTML, when you need to stay within a strict context window, when you want BM25-ranked relevance filtering against a specific query, or when you need structured/skeleton extraction rather than raw HTML. Prefer it over generic web scrapers when token efficiency and LLM cost savings are a priority.

## Known failure modes

- Invalid or unreachable URL returns an error status
- max_tokens set below minimum of 20 causes validation failure
- mode=budget without a query may return unfiltered content
- Raw HTML too large may hit processing limits
- Payment required (HTTP 402) if x402 micropayment is not configured
- Cache miss on first fetch may add latency

## How this service works

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

## Output

Returns a distilled representation of the webpage in the requested mode (Markdown, structured JSON, skeleton outline, or BM25 budget excerpt), along with an ROI proof object showing raw tokens, distilled tokens, tokens saved, compression ratio, and estimated LLM cost saved in USD. Also includes cache status and billing details.
