# Hosaka

Company data for AI agents, paid per call in USDC. Reads a company's own DNS to
find every third-party vendor it can be proven to use, and returns the record
proving each one. No signup, no API key, no subscription.

## Endpoints

Every paid endpoint takes `{"domain": "figma.com"}`. A URL works too.

- `POST /lookup` $0.005 — Use when you have a company domain and need to know what the company is before spending more. Returns the company name and site title, domain age, registrar, mail provider, DNS provider, DMARC and HTTPS status, and a count of the third-party vendors detected. One call, no signup, no API key. The cheapest way to qualify a domain before buying a fuller record.
- `POST /dossier` $0.02 — Use when you need a company's technology and vendor stack from its domain alone. Returns every third-party service it runs on — the software and tools behind its mail, DNS, CDN, analytics, payments, support and hosting — each with the DNS record or loaded script that proves it, plus registration, certificate and site facts. Technographics and SaaS detection without a subscription.
- `POST /people` $0.35 — Finds the people who work at a company from its domain alone: named employees with job title, seniority, location and profile link. Use it when the domain is all you have, because most people-data endpoints want an email or a LinkedIn URL before they will answer. Also returns the company's proven third-party vendor stack in the same call, so one purchase answers who works there and what they run.
- `POST /executives` $0.4 — Finds the decision makers at a company from its domain alone: owners, founders, C-level, partners, VPs, heads and directors, each with title, location and profile link. Use it when the domain is all you have, because endpoints that enrich a known person want an email or a profile URL first. Also returns the company's proven vendor stack, so one call answers who decides and what they already run.
- `POST /contacts` $0.02 — Use when you need to reach a company rather than a named person: the emails, phone numbers and social accounts it publishes about itself, gathered from its own site. Also returns every third-party vendor the company can be proven to use, with the record proving each. For support, sales and abuse contact discovery from a domain.
- `POST /preview` free — vendor count and a sample, to see the shape before paying
