# 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 llms-generator.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 for B2B lead enrichment capabilities, returning matching endpoints with token-compressed results and prompt-guard 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 llms-generator-agentdiet-dev-b2b-lead-enrichment-via-universal-a2a-6051b1ab
```

Example prompt: Search the MCP tool index for 'company enrichment' capabilities so I can find which available agent tools can enrich B2B leads with firmographic data like industry, headcount, and revenue.

## When to prefer this

Choose this endpoint when you need to discover which MCP servers or A2A agent tools are available for B2B lead enrichment specifically, rather than calling a dedicated enrichment API directly. Ideal for agent orchestrators that need to dynamically route to the best available tool, or when you want to compare multiple enrichment sources before committing. The built-in token compression and prompt firewall make it safer and cheaper than manually enumerating tool registries.

## Known failure modes

- Empty query string returns a 400 validation error
- No matching tools found returns an empty result set
- Prompt-Guard firewall may block queries it flags as potentially malicious
- x402 payment failure results in 402 response if payment is not properly attached
- Malformed endpoint URL in query field may return verification 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://llms-generator.agentdiet.dev/v1/workflows/b2b-lead-enrichment)

## Output
