## 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 mcp-compiler-agentdiet-dev-b2b-lead-enrichment-via-universal-a2a-mcp-f4a61d7d
```

Example prompt: Search the MCP tool index for B2B lead enrichment capabilities — I need to find which tools can enrich company contact and firmographic data given a company name or domain.

## When to prefer this

Choose this endpoint when you need to discover which MCP servers or A2A agents can perform B2B lead enrichment without knowing the specific tool ahead of time, or when you want to route a lead enrichment task through a single meta-connection rather than integrating multiple providers separately. Ideal for agent orchestration pipelines that need dynamic tool selection.

## Known failure modes

- No matching tools found for the given query — returns empty results
- Query string too vague — may return irrelevant or low-confidence tool matches
- Rate limiting or payment required if x402 payment not provided
- Upstream MCP servers temporarily unavailable — partial results returned
- Malformed query parameter causes validation 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://mcp-compiler.agentdiet.dev/v1/workflows/b2b-lead-enrichment)

## Output

Returns a structured list of matched MCP servers or A2A tools relevant to the B2B lead enrichment query, including tool names, capability descriptions, and routing references, compressed for token efficiency.
