## 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-b2b-lead-enrichment-via-universal-a2a-d3c1adeb
```

Example prompt: Search the MCP tool index for 'company enrichment' capabilities — I need to find which agent tools can enrich a B2B lead with firmographic data like company size, industry, and revenue.

## When to prefer this

Use this endpoint when you need to discover which MCP server or A2A tool can perform B2B lead enrichment without knowing the specific provider in advance; ideal for meta-routing across a large ecosystem of 500+ indexed tools with a single query rather than calling each discovery API individually.

## Known failure modes

- Query too vague — returns no matching tools or low-relevance results
- Endpoint URL verification fails if target is offline or non-compliant
- Rate limiting or 402 payment required if call quota exceeded
- Firewall (Prompt-Guard) blocks query if it appears adversarial
- Empty results if no indexed MCP server matches the capability query

## 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/b2b-lead-enrichment)

## Output

Returns a list of matched MCP server endpoints or A2A tools relevant to the capability query, with compressed metadata (85% token reduction) and prompt-guard filtered results pointing to the best-fit enrichment services available.
