## 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 company-enrich-agentdiet-dev-universal-a2a-mcp-tool-discovery-safe-6f1ee8fa -d '<json body>'
```

Example prompt: Search for an MCP tool that handles company enrichment and B2B lead data — I need to find the right endpoint to plug into my agent pipeline.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP server or A2A tool to call for a given capability, rather than hardcoding tool URLs. Especially useful for swarm orchestration, multi-step pipelines, or when the right downstream tool is unknown at design time. The built-in 85% token compression and Prompt-Guard firewall make it preferable over raw tool registries when safety and token budget matter.

## Known failure modes

- Empty query string returns validation error
- Query too vague returns low-confidence or empty match list
- No matching tools found for niche capability returns empty results object
- Network timeout if downstream MCP index is unreachable
- Malformed idempotency key header causes request rejection

## 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://company-enrich.agentdiet.dev/v1/workflows/execute)

## Output

Returns a compressed list of matching MCP servers or A2A tool endpoints relevant to the search query, including endpoint URLs, capability summaries, and routing metadata, with token usage reduced by up to 85% via built-in compression and prompt-injection firewall screening applied to results.
