Implicents & Pricing

Implicents are our usage currency for the API. Most endpoints cost 1 Implicent — 100 are included with signup.

0Implicents

Discovery

Resolve, batch resolve, suggest — rate-limited instead of Implicent-metered (20/min on the free tier, 120/min on plus).

1Implicent

Search, profiles & more

Search, company profile (base), changes, peers, nearby, people, announcements — covers nearly every endpoint.

5Implicents

Financials

Financials — standalone or as a surcharge on the company profile (then 5 instead of 1 Implicent for the same call).

Exception: GET /v2/companies/{id} costs 1 Implicent — with ?include=financials the same call rises to 5 Implicents. include=people and include=announcements stay at 1 Implicent.

MCP Server

Company Data Directly in Your AI Agent

Our Model Context Protocol (MCP) server is live at mcp.implisense.com — so AI clients like Claude, Cursor, or other MCP-capable clients can query German company data directly. It uses the same bearer token as the REST API.

Access via ChatGPT can be set up on request, just like for Claude.

Example: Claude Desktop

claude_desktop_config.json 
{
  "mcpServers": {
    "implisense": {
      "url": "https://mcp.implisense.com",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}
