# AgentDiet Universal MCP Gateway

> AgentDiet Universal MCP Gateway is a paid API for AI agents from status.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Compresses and distills AI agent context windows via a universal MCP gateway, reducing token usage by up to 85-91% through deterministic context de-bloating

## Facts

- Endpoint: GET https://status.agentdiet.dev/v1/universal-mcp-gateway?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-22
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agentdiet-universal-mcp-gateway-8f67169a
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_KHm9Vg2kW_HXsElwRDSrb

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-universal-mcp-gateway-8f67169a
```

Example prompt: Can you run my current context through AgentDiet's universal MCP gateway to compress it and cut down the token count — I want to see the compression ratio proof after it's done.

## When to prefer this

Choose this endpoint when your AI agent pipeline needs to deterministically reduce context window size before passing to an LLM, especially when operating under strict token limits or cost constraints. Prefer this over general summarization when you need a measurable compression ratio proof and deterministic, reproducible output. Ideal for A2A and MCP workflows that settle micropayments in USDC on Base via x402.

## Known failure modes

- Missing required 'input' object returns validation error
- Invalid 'type' field (must be 'http') causes rejection
- Unsupported HTTP method (not GET or POST) returns enum error
- Payment not settled in USDC on Base causes x402 authorization failure
- Empty or malformed query param causes incomplete compression result
- Service node unavailable returns non-200 status

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing the distilled context, a 'status' field ('ok' on success), and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%), confirming how much token reduction was achieved.
