Spanish company data API: enrich your CRM automatically
How to use a REST API to add phone and email for Spanish companies to your CRM leads, forms or Clay, Make and n8n workflows, with example calls and best practice.

International enrichment tools are strong on large companies and weak on Spanish SMEs and sole traders, which are 99 % of the market. If your team works hundreds of Spanish companies a month, copying numbers from a website doesn't scale. An API makes the data arrive on its own.
Typical use cases
- Enrich trial sign-ups. A Spanish company tries your SaaS; the API adds the phone and sales calls within an hour.
- Shorten forms. Ask only for company name and email; fill in the rest.
- Clean your CRM. Recover the current contact for old clients.
- Build lists in Clay by province and size.
How it works
- Search by name, tax ID or filters (province, size, available contact). The response says whether email and phone exist.
- Reveal what you need. You pay only for what's delivered.
POST /api/v1/companies/search
{ "query": "talleres", "province": "30", "contact": "phone", "limit": 20 }
Authentication, limits and batches are in the API documentation.
Volume pricing

Best practice

- Respect rate limits and use batches.
- Internal use only: data is licensed to your organisation and can't be resold.
Frequently asked questions
Does the API charge per query or per data point?+
Searching and seeing which data exists doesn't consume contact credits. You pay only when you reveal an email or phone that exists.
Does it work with Clay or HubSpot?+
Yes. It's a REST API with JSON responses, compatible with any tool that makes HTTP requests: Clay, Make, n8n, Zapier or your own code.
