# AgentDiet MCP Gateway Context Diet

> AgentDiet MCP Gateway Context Diet 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).

Returns a compressed, distilled context snapshot from the AgentDiet MCP/x402/A2A broker network, proving ROI via compression ratio metrics.

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-mcp-gateway-context-diet-64da00a9
```

Example prompt: Pull me a context diet snapshot from the AgentDiet broker using a GET request so I can see what compressed intelligence is available — I want to check the compression ratio and the distilled data payload.

## When to prefer this

Choose this endpoint when your agent needs a cost-efficient, compressed context snapshot from the AgentDiet MCP broker network and you want quantifiable ROI proof (compression ratio) rather than raw, unfiltered MCP server responses. Prefer it over direct MCP server queries when token budget is constrained or when you need a single aggregated context source across thousands of servers.

## Known failure modes

- Missing or malformed 'input' object returns a validation error
- Unsupported method value (not GET or POST) causes schema rejection
- Payment failure or insufficient USDC balance returns 402 response
- Invalid or unreachable 'url' query param may return empty data or error
- Network timeout from broker-side MCP server aggregation

## How this service works

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

## Output

Returns a JSON object with a 'data' field containing the compressed context payload, a 'status' field ('ok' on success), and an 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) demonstrating the efficiency gain of the distilled context.
