# AgentDiet X402-BROKER Alpha Stream

> AgentDiet X402-BROKER Alpha Stream is a paid API for AI agents from mcp-gateway.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Proxies and routes HTTP requests to a network of 31,390+ MCP servers, x402 APIs, and A2A agents, settling payments in USDC on Base.

## 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-x402-broker-alpha-stream-7833df56
```

Example prompt: Route a GET request to the target MCP server or x402 API I need, handle the USDC micropayment automatically on Base, and return the result — I want to reach one of the 31,390+ services through the AgentDiet broker without setting up individual payment channels.

## When to prefer this

Choose this endpoint when your agent needs to access any of 31,390+ MCP servers, x402 APIs, or A2A agents through a single unified gateway that handles USDC micropayment settlement automatically on Base. Prefer it over direct API calls when you don't want to manage x402, L402, or MPP payment handshakes yourself, or when you want deterministic routing and ROI proof alongside your response.

## Known failure modes

- Insufficient USDC balance to settle the $0.01 micropayment on Base — returns payment required error
- Target MCP server or x402 API is unreachable or offline — returns error in data field
- Invalid or missing 'input.type' or 'input.method' fields — schema validation error
- Target service does not exist in the 31,390+ indexed catalog — not found response
- Network congestion on Base causing payment settlement delay — timeout or pending status

## 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 proxied service response, a 'status' field ('ok' on success), and an 'roi_proof' object including a compression_ratio_pct metric indicating how efficiently the response was delivered.
