# B2B Lead Enrichment via Universal A2A & MCP Tool Discovery Router

> B2B Lead Enrichment via Universal A2A & MCP Tool Discovery Router is a paid API for AI agents from whale-momentum.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Discovers and routes to B2B lead enrichment capabilities across 500+ indexed MCP servers and A2A tools using a single query connection with token compression and prompt firewall.

## 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 whale-momentum-agentdiet-dev-b2b-lead-enrichment-via-universal-a2a-a59932d6
```

Example prompt: Search the agentdiet MCP router for 'company enrichment' tools — I need to find what's available to enrich B2B leads with company details and contact info.

## When to prefer this

Choose this endpoint when you need to discover which of 500+ MCP servers or A2A tools can handle a B2B lead enrichment or company intelligence task, rather than calling a single enrichment API directly. Ideal when you don't know which specific tool to use, want token-efficient routing across multiple agent tools, or need a safe-proxied connection with prompt injection protection.

## Known failure modes

- Empty query string returns validation error (minLength: 1)
- Query too vague may return zero matched tools
- Endpoint URL verification may return 404 if target is offline
- HTTP 402 payment required if x402 credits are exhausted
- Slow or unavailable upstream MCP servers may cause partial results
- Prompt-Guard firewall may block queries flagged as injection attempts

## 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://whale-momentum.agentdiet.dev/v1/workflows/b2b-lead-enrichment)

## Output

Returns a list of matched MCP servers or A2A tools relevant to the query, including tool metadata, capability descriptions, and routing information — delivered with 85% token compression through the meta-router layer. May include direct proxy access to the matched capability.
