# B2B Lead Enrichment via A2A & MCP Tool Discovery Router

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

Searches a meta-index of 500+ MCP servers and A2A tools for B2B lead enrichment capabilities, returning matching tool endpoints with token-compressed results and prompt-guard filtering.

## Facts

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 github-audit-agentdiet-dev-b2b-lead-enrichment-via-a2a-mcp-tool-f2cd754c
```

Example prompt: Search the MCP and A2A tool index for 'company enrichment' capabilities — I want to find tools that can fill in missing firmographic data on my B2B leads.

## When to prefer this

Use this endpoint when you need to discover which MCP server or A2A tool to use for B2B lead enrichment rather than calling an enrichment API directly — ideal when you don't know which specific tool is available or want to compare options across 500+ indexed servers with a single query.

## Known failure modes

- Empty results if query is too narrow or uses uncommon terminology
- Generic or irrelevant tools returned if query is ambiguous
- HTTP 402 payment required if x402 payment header is missing or malformed
- Timeout if the meta-index is under load
- Prompt-guard may block queries containing injection-like patterns

## 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://github-audit.agentdiet.dev/v1/workflows/b2b-lead-enrichment)

## Output

Returns a list of matching MCP server or A2A tool endpoints relevant to the B2B lead enrichment query, with token-compressed metadata, capability descriptions, and routing information for each matched tool, filtered through a prompt-guard firewall.
