## 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 cve-intel-agentdiet-dev-b2b-lead-enrichment-via-a2a-mcp-tool-1cf840fd
```

Example prompt: Search the agentdiet tool index for 'company enrichment' capabilities — I need to find the best available MCP server or A2A tool that can enrich B2B leads with firmographic data like company size, industry, and contact details.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover the best available MCP server or A2A tool for B2B lead enrichment without hardcoding a specific provider. Ideal for agentic workflows that need to route capability requests across a broad index of 500+ tools with built-in safety filtering and token-efficient responses.

## Known failure modes

- Empty or vague query returns no useful matches
- Query returns irrelevant tools if search terms are too broad
- Endpoint returns 402 Payment Required if x402 payment header is missing or invalid
- Slow response if backend indexes many servers simultaneously
- Prompt injection attempts blocked by Prompt-Guard firewall, which may also flag legitimate edge-case queries

## How this service works
