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

Fetches a URL or raw HTML and distills it into compact, agent-ready tokens using BM25 budget control and multiple extraction modes

## 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 shopify-spy-agentdiet-dev-agentdiet-web-distillation-api-9c590b3d
```

Example prompt: Can you fetch https://stripe.com/docs/payments and distill it into compact markdown, keeping it under 500 tokens and focusing on the query 'payment intents'?

## When to prefer this

Use this endpoint when an AI agent needs to feed web page content into an LLM context window and wants to minimize token usage and cost. It is especially valuable when dealing with long pages, documentation sites, or HTML-heavy content where only the relevant portion matters. Prefer it over raw fetch+parse approaches when you need BM25 query-focused excerpting, clean Markdown output, or strict token budget control. The built-in ROI proof makes it easy to justify token savings.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Token budget too low (below 20) rejected by schema validation
- Raw HTML too large may timeout or exceed processing limits
- BM25 query missing when mode=budget may produce unfiltered output
- Payment/402 not fulfilled results in access denied
- Paywalled or bot-blocked pages may return incomplete 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://shopify-spy.agentdiet.dev/api/diet)

## Output

Returns a JSON object with a 'data' field containing the distilled content (Markdown, structured JSON tables, skeleton outline, or BM25 budget excerpt depending on mode), plus an 'roi_proof' block showing raw vs distilled token counts, compression ratio, tokens saved, and estimated LLM cost saved in USD. Also includes cache hit/miss status and billing details.
