# DeFi Token Due Diligence via Universal A2A & MCP Tool Discovery Router

> DeFi Token Due Diligence via Universal A2A & MCP Tool Discovery Router is a paid API for AI agents from alpha-stream.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches an index of 500+ MCP servers and A2A tools to find, proxy, and route AI agent capabilities matching a given query, with token compression and prompt safety filtering.

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 alpha-stream-agentdiet-dev-defi-token-due-diligence-via-universal-a2a-7a2798dc
```

Example prompt: Search the MCP and A2A tool index for any servers or agents that can handle DeFi token due diligence — I need to find what capabilities are available for on-chain risk and DEX token intelligence.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool can handle a given capability, rather than hardcoding a specific tool. Especially useful for swarm orchestration scenarios, capability routing, and when you want token-compressed tool metadata with built-in prompt safety filtering. Prefer this over direct tool invocation when the right tool is unknown upfront.

## Known failure modes

- Empty results if the query is too vague or no matching tools are indexed
- Timeout if the upstream MCP or A2A endpoint is unavailable
- Payment required (HTTP 402) if x402 micropayment is not attached
- Prompt-Guard rejection if the query is flagged as adversarial or prompt-injection attempt
- Malformed query returns 400 validation 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://alpha-stream.agentdiet.dev/v1/workflows/defi-token-due-diligence)

## Output

Returns a structured list of matching MCP servers, A2A agent tools, or routed workflow results relevant to the query. Metadata is token-compressed by up to 85% and has passed through the Prompt-Guard firewall to filter malicious prompt injections. Results include endpoint details, capability descriptions, and routing information.
