## 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 b2b-account-firmographics-lookup-238f6668
```

Example prompt: Can you pull the firmographic profile for the company at stripe.com — I need their industry, size, and revenue range for a sales prospecting report?

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call firmographic enrichment for a business domain without committing to a subscription-based data provider. It is well-suited for ad hoc B2B lead research, CRM enrichment pipelines, or agent workflows that need company intelligence on demand. Prefer alternatives like Clearbit or ZoomInfo if you need deeply structured, high-confidence firmographic data with SLA guarantees; use this for cost-efficient, agent-native lookups settling in USDC on Base.

## Known failure modes

- Unknown or unrecognized domain returns empty or sparse data object
- Payment failure via x402 results in HTTP 402 response before data is returned
- Invalid input schema (missing required `type` or `method` fields) returns a validation error
- Domain with no firmographic record returns an empty data object with status ok
- Rate limiting or gateway timeout may occur under high load

## Output

Returns a JSON object with a `data` field containing firmographic attributes for the queried domain (e.g. industry, company size, employee count, revenue estimates), a `status` field indicating success, and an `roi_proof` object showing compression ratio metrics. The response is highly compressed relative to raw data sources (~91% compression ratio).
