## 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 agentdiet-b2b-domain-enrichment-201c6fbf
```

Example prompt: Can you pull up the B2B company intelligence for the domain 'stripe.com' and give me whatever firmographic or business metadata is available?

## When to prefer this

Choose this endpoint when you need quick, metered B2B domain enrichment paid per-call in USDC via x402, particularly in agent workflows that require deterministic, on-demand company intelligence without committing to a subscription data provider. It is well-suited for agentic pipelines that process domains one at a time and want a lightweight firmographic lookup with verifiable ROI compression metrics.

## Known failure modes

- Missing or invalid domain query parameter returns an error or empty data object
- Domain not found in underlying data sources returns sparse or empty enrichment
- Payment failure (insufficient USDC balance) results in 402 response blocking execution
- Unsupported HTTP method returns a schema validation error
- Rate limiting or gateway timeout returns a 5xx error

## 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

A JSON object with a 'data' field containing enriched B2B company metadata for the given domain, a 'status' field confirming success, and an 'roi_proof' object including a compression_ratio_pct indicating how much raw data was condensed (e.g. 91.4%).
