# AgentDiet Web Distillation API

> AgentDiet Web Distillation API is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.001/call, status unknown (last checked 2026-10-21).

Fetches and compresses a URL or raw HTML into compact, agent-ready tokens using BM25 budget control and multiple extraction 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 whale-momentum-agentdiet-dev-agentdiet-web-distillation-api-d83536fc
```

Example prompt: Can you distill https://stripe.com/docs/api into compact markdown and tell me how many tokens you saved compared to the raw page?

## When to prefer this

Choose this endpoint when an AI agent needs to ingest live web content but must stay within a token budget — especially when raw HTML is too large for direct LLM context. It is ideal for agentic pipelines that need to read documentation, news, or product pages on the fly and pass only the essential content downstream. The BM25 budget mode makes it uniquely suited for targeted topic extraction from long pages.

## Known failure modes

- URL is unreachable or returns a non-200 status — distillation fails with a fetch error
- Malformed or empty HTML input returns empty or error data object
- max_tokens set below the minimum of 20 returns a validation error
- mode=budget without a query may return unfocused or degraded output
- Payment failure via x402 prevents the call from being processed
- Rate limiting or timeouts on large or slow-loading pages

## How this service works

Distill a URL or raw HTML payload with BM25 budget control (Live x402 v2, IETF MPP & MCP endpoint at https://whale-momentum.agentdiet.dev/api/diet)

## Output

Returns a distilled version of the webpage or HTML in the chosen format (Markdown, structured JSON with tables/metadata, skeleton outline, or BM25-focused excerpt), plus an ROI proof object showing raw vs distilled token counts, tokens saved, compression ratio, LLM cost saved in USD, and optional billing and cache hit/miss metadata.
