## 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-dev-universal-a2a-mcp-tool-discovery-safe-proxy-swarm-router-3ece579a
```

Example prompt: Search agentdiet's meta-router for any available MCP tools that handle SEC filings or company enrichment — I want to find and route to the right one without setting up multiple connections.

## When to prefer this

Choose this endpoint when an agent needs to discover and route to the right MCP server or A2A tool without managing hundreds of individual connections, especially when token efficiency matters or when prompt injection protection via the Prompt-Guard firewall is required.

## Known failure modes

- No matching tools found for the given query — returns empty result set
- Invalid or unreachable endpoint URL when used in verification mode — returns compliance error
- Query too vague — low-confidence results with irrelevant tool matches
- Service unavailable if the meta-router index is temporarily down
- Payment failure if x402 micropayment of $0.01 is not completed

## How this service works

Single-connection meta-router indexing 500+ MCP servers & A2A tools with 85% token compression and Prompt-Guard firewall. (Live x402 v2, IETF MPP & MCP endpoint at https://agentdiet.dev/v1/workflows)

## Output

A list of matching MCP servers or A2A tools ranked by relevance to the query, including their endpoint metadata, capability descriptions, and routing details, returned through a single compressed connection.
