VERDICT

Should I use Openapi?

Largest Certified API Marketplace — 400+ API services, millions of certified data points - openapi.com

Depends. Buy if your developers need certified company, ID, or vehicle data via API and pay-per-call pricing fits your volume. Skip if you searched for OpenAI or the OpenAPI spec — this is neither — or if you need no-code lookups.

Confidence

Medium. Based on 14 public sources; several search results matched only the name (OpenAI, OpenAPI Initiative) and were excluded. Independent user reviews are scarce.

Best for

  • Italian/EU developers automating registry lookups
  • Insurance, real-estate, and automotive data workflows
  • Usage-based buyers testing APIs cheaply first

Not for

  • Anyone who actually wanted OpenAI or the OpenAPI spec
  • Non-technical teams wanting no-code dashboards
  • One-off lookups — manual registry searches are free
  • Teams without developers to integrate and maintain API calls

Gotchas - check before you buy

Vendor data authority matters — staff claim official-register sourcing; verify for your use case
