# 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 token-intel.agentdiet.dev, paid per call via MPP, $0.01/call, status unknown (last checked 2026-10-21).

Searches and routes queries across 500+ indexed MCP servers and A2A tools to find, proxy, and return enriched B2B lead and capability data with token-compressed results.

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 token-intel-agentdiet-dev-b2b-lead-enrichment-via-universal-a2a-mcp-03ac0664
```

Example prompt: Search the MCP and A2A tool index for something that can do B2B lead enrichment or company data lookup — I want to find the right agent tool to enrich a prospect list.

## When to prefer this

Choose this endpoint when you need to discover which MCP server or A2A agent to call for a specific capability, rather than calling a capability directly. Ideal for dynamic agent orchestration where the right downstream tool is not known in advance, or when you want a single connection point that proxies across 500+ tools with token compression and prompt injection protection.

## Known failure modes

- No matching tools found for the given query — returns empty or low-confidence result set
- Query too vague or short (minLength:1 enforced) — may return broad or irrelevant matches
- Upstream MCP server or A2A tool is unavailable — router may return partial results
- Payment not completed (HTTP 402) — endpoint requires $0.01 USDC via x402 before results are returned
- Rate limiting or SLA breach on downstream tool — latency spike or timeout

## 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://token-intel.agentdiet.dev/v1/workflows/b2b-lead-enrichment)

## Output

Returns a token-compressed set of matching MCP server endpoints or A2A tools relevant to the search query, including capability descriptions and routing metadata, filtered through a Prompt-Guard firewall for safe proxying.
