An honest comparison for teams weighing Roaring against Prometiam for Swedish company data by API. Roaring, a Swedish company that describes itself as built on Nordic data quality, is a risk and compliance data platform for banks, insurers, the public sector and other companies, with REST APIs, webhooks and an in-app product called Roaring Lookup. Prometiam is the register-record API: an organisationsnummer, a Swedish VAT number or a name in, the Bolagsverket record out. All Roaring facts on this page were read on its own sites on 2026-09-30.
Breadth of data. Its data page lists company information and financial information, board members and board assignments, authorised signatories, ownership and group structure, beneficial owners, PEP, sanctions lists, adverse media, credit ratings and risk indicators, where the Swedish record on Prometiam is the register record only. Nordic reach: its data page filters by Sweden, Norway, Denmark, Finland and Spain, plus a global set. Product surface: REST-based APIs, webhooks for monitored datasets, a Flow Builder and a sandbox on its developer portal, an in-app Lookup product with reports and monitoring, and ready-made use cases for onboarding, compliance, authorised signatories and supplier audits.
A price you can see and start on. Prometiam publishes every tier from a 14-day trial (1,000 API calls per month, no credit card) through Starter at €9.99 a month to Scale at €99.99, monthly or annual, each with its call allowance and rate limit. Roaring's pricing page lists a free sandbox, a paid plan for its integrations with usage charges added on top, and a custom plan. The official record, validated: the organisationsnummer check digit and third-digit rule, the SE VAT alias and the register's status and dates, in the same response shape as Spain, France, the UK, Ireland, Poland, Norway and Finland.
Company records from the Swedish Companies Registration Office (Bolagsverket): legal name, legal form, status, registered address, activity code and dates; no officers, no corporate-event stream, no monitoring, no registry-compliance signal and no insolvency notices, and sole traders (enskild näringsverksamhet) are never served.
If your workflow is a lookup, resolving a customer's identifier or a few typed letters into a company record for an onboarding form, an invoice or a CRM row: every registry identifier is one parameter — NIF/CIF (Spain), SIREN/SIRET (France), company number (UK), CRO number (Ireland), KRS number (Poland), organisasjonsnummer (Norway), Y-tunnus (Finland), organisationsnummer (Sweden) — and ?name= is a normalised partial match a type-ahead field can call on every keystroke, across one schema for all live countries. Auth is one bearer key; rate limits scale 10 to 600 requests/minute by tier. A TypeScript SDK (prometiam-risk-api on npm) and an MCP server (prometiam-risk-mcp, also at /mcp) are both published; no Python SDK yet. Pricing is monthly or annual (ten months' price for twelve). Free — 14-day trial. 1,000 API calls per month, 10 requests/minute, no credit card. Subscribing keeps the same key working. The free plan is not an ongoing one. Free identifier lookup tools, including an organisationsnummer lookup, run the same call without a key.
