Option 1: HTTP Request (for fixed flows)

The most reliable way when the flow is always the same — for example "fetch new incorporations in a postcode area every morning".

1. Create credentials: Credentials → New → Header Auth
   • Name: Authorization
   • Value: Bearer <YOUR-API-KEY>
2. Node HTTP Request
   • Method: POST
   • URL: https://indizio.rexago.com/api/v1/companies/search
   • Authentication: Generic Credential Type → Header Auth → the ones just created
   • Send Body: JSON, for example:

{
  "countries": ["de"],
  "postal_prefixes": ["70", "71"],
  "founded_after": "2025-01-01",
  "per_page": 25
}

The hits are under data, paging under meta.

Option 2: MCP Client Tool (for AI agents)

When an AI Agent node should decide itself what to query:

1. Add MCP Client Tool as a tool to the agent.
2. Endpoint: https://indizio.rexago.com/mcp — transport "HTTP Streamable" if offered.
3. Authentication: Header Auth with name X-Api-Key and your key as the value.

Good to know

Every call spends credits — including in a workflow that runs every minute. Set per_page deliberately and keep an eye on usage in your customer area.
