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 polymarket-odds-agentdiet-dev-defi-token-due-diligence-via-a2a-mcp-cc6b9261
```

Example prompt: Search the MCP and A2A tool index for 'defi token due diligence' capabilities — I need to find available tools for on-chain token risk analysis and company enrichment that I can route my agent through.

## When to prefer this

Choose this endpoint when an AI agent needs to dynamically discover which MCP servers or A2A tools support a given capability — especially for DeFi, on-chain, or token due diligence workflows — and wants compressed, safety-filtered results in a single connection rather than querying individual tool registries.

## Known failure modes

- Empty query string returns validation error
- No matching tools found for obscure capability queries
- Firewall blocks queries containing prompt injection patterns
- Rate limiting or payment failure (HTTP 402) if x402 payment not provided
- Upstream MCP server unavailability may reduce result completeness

## 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://polymarket-odds.agentdiet.dev/v1/workflows/defi-token-due-diligence)

## Output

A compressed (up to 85% token reduction), Prompt-Guard firewall-filtered list of matching MCP servers and A2A tools relevant to the query, including tool metadata and routable endpoint references for the requested capability domain.
