## Description
Enrich a company from its domain. A free keyless preview returns the email provider, the SaaS and tech stack detected from DNS, and domain age plus registrar from RDAP. The paid depth record adds firmographics (name, industry, social links, contacts), legal registration (VAT or company number, digit-validated), office address, and a live hiring signal read across 8 applicant-tracking systems. No API key to connect; the paid call settles in USDC on Base via x402.

## Tools
Capabilities this server exposes over MCP:

- **search_jobs** — Fetch live, normalized open job postings for one or more companies across 7 keyless ATS platforms (Greenhouse, Lever, Ashby, SmartRecruiters, Workday, Recruitee, Workable). Platform and board token are auto-detected from a bare slug or domain. Returns a unified schema: title, company, location, remote, url, source_platform, posted_at. Free. Derived layers (normalized comp, hiring-intent) and a hosted 10-ATS feed are metered — call get_premium_access.
- **resolve_company** — Resolve which applicant-tracking system a company uses and its board token, from a bare slug or domain. Returns {platform, token, via}. Free.
- **list_platforms** — List the supported ATS platforms this feed auto-detects and normalizes. Free.
- **enrich_preview** — Free keyless DNS/RDAP enrichment preview for a company domain: email provider (from MX), SaaS detected from DNS TXT, domain age + registrar (RDAP). A real taste of the paid /company/enrich, which adds a bounded site crawl (firmographics, contacts, social), tech-stack fingerprint, office address, legal registration (VAT / company number) and the live multi-ATS hiring block — call get_premium_access for the full record.
- **verify_email_preview** — Free keyless email-deliverability preview. Grades ONE address in full (real output): syntax, MX / implicit-MX routing, email provider, SPF/DMARC posture, disposable / role / free-provider flags, a derived edit-distance typo did-you-mean, and an A-F deliverability grade — no SMTP ping, no account. Any additional addresses return only {deliverable, grade}. A real taste of the paid /email/verify, which returns the full per-email record for up to 100 addresses in one x402 call — call get_premium_access for the metered endpoint.
- **get_premium_access** — Return the paid x402 rail: the metered depth layers (hosted 10-ATS search, normalized compensation, per-company hiring-intent signal, company enrichment, email deliverability) with exact prices (USDC on Base), the pay-to address, and how the 402 flow works. No account; an x402-aware client pays inline from the agent's wallet.

## Documentation

## What Company Enrichment MCP (DNS/RDAP + hiring signal) does

Company Enrichment MCP (DNS/RDAP + hiring signal) turns a company domain into structured enrichment data for agent workflows. The free preview focuses on signals available from domain infrastructure and registration records: email provider, detected SaaS and technology products, domain age, and registrar.

The paid depth record extends the result beyond technical domain signals. It can return company name, industry, social links, contacts, legal registration identifiers such as a VAT number or company number, office address, and a live hiring signal. Legal identifiers are digit-validated, and the hiring signal is read across eight applicant-tracking systems.

## How it works

An agent supplies a company domain for enrichment. The preview uses DNS-derived observations and RDAP registration data, allowing a keyless first-level lookup. The deeper request adds business and recruiting information, including a current hiring indicator based on ATS data.

Connecting does not require an API key. The paid request is handled through x402 and settles in USDC on Base. This creates a clear separation between the free domain preview and the paid, broader enrichment result.

## Setup and configuration

The service is designed for MCP use and can be connected without an API key. Applications should provide a company domain when invoking enrichment. A workflow that only needs email infrastructure, detected technology, domain age, or registrar data can use the free preview.

Use the paid depth record when the workflow also needs firmographics, contacts, legal registration, office location, social profiles, or the hiring signal. Payment for that call requires USDC on Base through x402, so the calling environment must support that payment flow.

## Tools and capabilities

- Free keyless company preview from a domain.
- Email-provider detection from DNS data.
- SaaS and technology-stack detection from DNS signals.
- Domain-age and registrar lookup through RDAP.
- Paid firmographic, contact, social, legal, and office enrichment.
- Live hiring signal checked across eight applicant-tracking systems.

The paid result includes legal registration data with digit validation for VAT or company numbers. The hiring output is intended as a live signal rather than a static company attribute, because it is read from applicant-tracking systems during enrichment.
