# AgentDiet Semantic Distillation

> AgentDiet Semantic Distillation is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-22).

Fetches a URL and strips 85-97% of HTML token bloat, returning semantically distilled content for AI agents

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/distill?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_C5UEZAGOoTMlnDX1iFWzf

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-semantic-distillation-5d87f219
```

Example prompt: Fetch https://en.wikipedia.org/wiki/Artificial_intelligence and strip out all the HTML bloat so I get back just the meaningful text content — I want the distilled version to minimize tokens.

## When to prefer this

Choose this endpoint when an AI agent needs to fetch and process web content but wants to minimize LLM token consumption — ideal for research pipelines, agentic browsing, or any workflow where raw HTML would overwhelm a context window. Particularly useful when cost-efficiency matters and the agent needs clean, readable text rather than structured data extraction.

## Known failure modes

- Invalid or unreachable URL returns an error status
- Target URL blocks bots or returns 403/429, resulting in failed fetch
- Malformed input schema (missing required `type` or `method` fields) causes validation error
- Payment failure via x402 protocol prevents execution
- Very dynamic JavaScript-rendered pages may yield incomplete distillation

## How this service works

AgentDiet Semantic Distillation (/v1/distill) — Strips 85-97% of HTML token bloat (https://mcp-gateway.agentdiet.dev/v1/distill)

## Output

A JSON object with a `data` field containing the distilled semantic content of the fetched URL, a `status` field indicating success, and a `roi_proof` object showing the compression ratio achieved (e.g. 91.4% token reduction).
