Syyni API

Finnish company and decision-maker data over HTTP. Filter the register, fetch the rows you need, and pay per row — with individual contact fields priced separately, and never charged when they are empty.

463,126

active companies in the trade register

130,551

named decision-makers, sourced from company websites

77

filters, from industry and region to buying signals

What makes it different

• Counting is free. Build and refine your filter against /count without spending anything. You only pay when you fetch rows.
• Empty fields are never billed. Ask for phone numbers and you pay only for the rows that have one. Every response tells you how many were empty.
• Fetching the same row again is free for 30 days. A retry loop, a crashed job or a badly scheduled sync will not produce a second invoice for the same data.
• There is a sandbox. Build the whole integration against real data without being billed, then swap one key to go live. See Sandbox.
• Every row carries its source. Decision-maker rows name the page the information was read from and the date it was last seen, so you can check any single row yourself.

A first request

Counts are free, so start there. This asks how many companies in Helsinki have a phone number on their website:

curl -H "Authorization: Bearer $SYYNI_API_KEY" \
  "https://syynilabs.fi/api/v1/companies/count?municipality=091&has_phone=true"

{
  "companies": 9713,
  "decision_makers": 24811,
  "companies_with_decision_makers": 4987,
  "billing": { "cost": "0.00", "currency": "EUR", "note": "Counts are free." }
}

What the API does not cover

This API serves company and decision-maker data only. Public-sector officials, trademark monitoring and the report products are sold through the web shop and custom work, not here. If you need those programmatically, tell us what you are building — the answer may well be yes, just not yet.
