Quickstart

Semantil finds companies, enriches domains, and discovers lookalikes. Choose the shortest way to get your first result.

Choose an API

Start from what you already know. The Playground exposes the same three core actions without requiring you to build the request by hand.

You have	Use	What it does
A company domain	Domain enrichment	Returns selected profile, technology, company, contact, commerce, or merchant-size data for that domain.
A description of a market	Company search	Finds companies using business-language search and verified catalog filters.
A strong customer or competitor	Lookalike	Uses one seed domain to return a ranked list of similar companies.

See copy-ready examples for each action, or open the API reference for every parameter and response schema.

Make your first API call

1. Create an API key

   Open API keys and create one key for this integration.

2. Verify the key

   curl -H "Authorization: Bearer $SEMANTIL_API_KEY" \
     "https://semantil.com/api/me"

   A 200 response means the key is ready. This authentication check does not consume credits.

3. Enrich one domain

   curl -H "Authorization: Bearer $SEMANTIL_API_KEY" \
     "https://semantil.com/api/domains/notino.pl?products=profile"

   This asks for the profile product. Check the live GET /api/products catalog for current products and usage units before setting a request budget.

Building with an agent?

Give it the OpenAPI contract or the compact llms.txt index. Both are generated from the current public documentation.
