## 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 enterprise-firmographics-api-via-agentdiet-mcp-gateway-c57a1059
```

Example prompt: Can you pull up the firmographic data for stripe.com — I need to know their industry, size, and other company details?

## When to prefer this

Use this endpoint when you need structured firmographic data (industry, employee count, funding, HQ location) for a company identified by its domain name, especially in B2B sales, lead enrichment, or account-based marketing workflows. Prefer this over general web search when you need structured, machine-readable company data rather than unstructured text, and when you're operating in an x402/USDC micropayment environment.

## Known failure modes

- Unknown or unregistered domain returns empty data object
- Invalid domain format causes input validation error
- Payment not settled in USDC on Base results in 402 response
- Rate limiting or gateway timeout for high-volume requests
- Domain exists but no firmographic data is available in the dataset

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing firmographic details about the queried company (industry, size, location, funding, etc.), a 'status' field indicating success, and a 'roi_proof' object showing compression ratio (e.g. 91.4%) indicating how much raw data was distilled.
