# AgentDiet MCP Gateway Swarm Execute

> AgentDiet MCP Gateway Swarm Execute 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).

Routes and executes queries across 31,390+ MCP servers, x402 APIs, and A2A agents via a unified broker endpoint, settling payments in USDC on Base.

## Facts

- Endpoint: GET https://mcp-gateway.agentdiet.dev/v1/swarm-execute?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-mcp-gateway-swarm-execute-6536928f
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_nhrlmWU2ZZahKeLm6Qj1k

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-swarm-execute-6536928f
```

Example prompt: Search for the latest information on AI agent frameworks by routing my query through the MCP swarm gateway — use a GET request with query 'AI agent frameworks 2024' and give me back whatever the swarm finds.

## When to prefer this

Choose this endpoint when you need a single, unified gateway to route queries across thousands of MCP servers, x402 APIs, or A2A agents without managing individual connections. It is best suited for agents that need broad coverage across many tools, want deterministic execution with micropayment settlement in USDC, or need an OpenRouter-style broker abstraction over the fragmented MCP/agent ecosystem.

## Known failure modes

- Missing required 'input' field returns validation error
- Invalid method enum (not GET or POST) causes request rejection
- Payment failure or insufficient USDC balance on Base blocks execution
- Downstream MCP server unavailable returns partial or empty data
- Malformed query parameters result in empty or irrelevant results
- Rate limiting or throttling if too many calls in quick succession

## 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 execution result, a 'status' field (e.g. 'ok'), and an 'roi_proof' object including a compression_ratio_pct metric indicating how efficiently the result was distilled from the swarm.
