### 2026-08-22 (score 42)

First indexed and scored.

## MCP tools (4)

### `hosaka_lookup` (~82 tokens)

Look up a company

Fast facts about a company from its domain: how old the domain is, its registrar, mail and DNS providers, whether DMARC and HTTPS are configured, and how many third-party vendors are visible. Costs $0.01 in USDC.

Input parameters:

- `domain` (string, required): Company domain, for example figma.com. A URL or a www prefix is fine.

### `hosaka_dossier` (~101 tokens)

Full company dossier

Everything hosaka_lookup returns, plus every third-party vendor the company can be proven to use — CRM, email, analytics, cloud, HR, payments — each with the DNS record, SPF include or loaded script that proves it. Also returns raw DNS, registration, certificate and site facts. Costs $0.07 in USDC.

Input parameters:

- `domain` (string, required): Company domain, for example figma.com. A URL or a www prefix is fine.

### `hosaka_contacts` (~102 tokens)

How to reach a company

Everything hosaka_dossier returns, plus every contact point the company publishes about itself — support and sales email addresses, phone numbers and social accounts, read from its own site. Use this when the question is how to reach the company. For named individuals who work there, use hosaka_people instead. Costs $0.02 in USDC.

Input parameters:

- `domain` (string, required): Company domain, for example figma.com. A URL or a www prefix is fine.

### `hosaka_people` (~91 tokens)

People who work at a company

Everything hosaka_dossier returns, plus named people who work at the company, sourced from a people-data provider. Cheaper than buying the contacts alone elsewhere. Use hosaka_contacts instead when a published support or sales address would answer the question. Costs $0.25 in USDC.

Input parameters:

- `domain` (string, required): Company domain, for example figma.com. A URL or a www prefix is fine.
