## 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-agent-router-36198b44
```

Example prompt: Search AgentDiet's meta-router for any available MCP tools or A2A agents that can handle web scraping tasks — I want to find everything indexed across its 500+ servers with a single query.

## When to prefer this

Choose this endpoint when an agent needs to discover or route to any of 500+ MCP servers or A2A tools without knowing the specific server address, or when you want a single-connection abstraction over a broad tool ecosystem with built-in token compression and safety filtering.

## Known failure modes

- Query returns no matching tools if the search term is too niche or not indexed
- Rate limiting or payment failure if USDC payment is not properly attached
- Prompt-Guard firewall may block queries that appear adversarial or unsafe
- Empty result set for very new or unlisted MCP servers not yet indexed
- Malformed query parameter may return 400 error

## 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/agent-router)

## Output

Returns a list of matching MCP servers, A2A tool endpoints, or routing metadata relevant to the query, with token-compressed responses and safety filtering applied via the Prompt-Guard firewall.
