# DeFi Token Due Diligence Workflow via x402broker

> DeFi Token Due Diligence Workflow via x402broker is a paid API for AI agents from x402broker.com, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Runs a DeFi token due diligence workflow, querying the x402broker meta-router index of 500+ MCP servers and A2A tools with token compression and prompt firewall protection.

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 x402broker-com-defi-token-due-diligence-workflow-via-x402broker-46f00f77
```

Example prompt: Search the x402broker tool index for any MCP servers or A2A agents that can do DeFi token due diligence — something like 'on-chain risk' or 'DEX token intelligence'.

## When to prefer this

Choose this endpoint when an agent needs to discover, route to, or safely proxy one of 500+ MCP or A2A tools in a single connection — especially for DeFi/on-chain workflows, or when token compression and prompt injection protection are required. Prefer over direct tool connections when the target tool is unknown, when you need firewall-guarded proxying, or when building swarm-style multi-agent pipelines.

## Known failure modes

- Empty or too-vague query returns no tool matches
- Queried capability not indexed in the 500+ server catalog
- Payment not completed (HTTP 402) blocking the response
- Prompt-Guard firewall blocks query flagged as adversarial
- Endpoint URL verification fails if the target is offline or non-compliant

## 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://x402broker.com/v1/workflows/defi-token-due-diligence)

## Output

Returns a structured object containing discovered tool metadata, matched MCP server or A2A endpoint details, routed responses with token-compressed output, and any prompt firewall verdicts — surfacing which of the 500+ indexed tools best match the queried capability.
