# AgentDiet Web Distillation API

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

Fetches a URL 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 agentdiet-dev-agentdiet-web-distillation-api-63e44d86
```

Example prompt: Fetch https://stripe.com/docs/payments/accept-a-payment and distill it into compact markdown, keeping it under 2000 tokens and focusing on the BM25 query 'accept payment intent'.

## When to prefer this

Choose this endpoint when you need to feed live web content into an LLM pipeline without blowing your context window. It is especially valuable when you need BM25-ranked relevance filtering (mode=budget with a query) to extract only the sections pertinent to your task, or when you want structured JSON tables/metadata instead of raw HTML. Prefer it over raw fetch+parse approaches when token cost and context efficiency matter, and when you want built-in ROI metrics proving the compression value.

## Known failure modes

- URL unreachable or returns non-200 — distillation cannot proceed
- Invalid or malformed URL string — request rejected
- Token budget too low (below 20) — validation error
- HTML payload too large — may timeout or be truncated
- BM25 query missing when mode=budget — incomplete results
- Payment failure via x402 — endpoint returns 402 with payment details
- Cached stale content returned for dynamic 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://agentdiet.dev/v1/pdf-extract)

## Output

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