Terms of Service

Last updated: April 2026

1. Agreement

By creating an account or using the ApiOne API at apione.store, you agree to these Terms of Service. If you are using ApiOne on behalf of a company, you represent that you have authority to bind that company. These terms apply to all plans including the free tier.

2. The service

ApiOne provides a B2B data enrichment API including company enrichment, people enrichment, email finding, email verification, tech stack detection, and signal detection. We provide the API on a best-effort basis. We do not guarantee that all enrichment results will be complete or accurate, as data coverage varies by company and region.

3. Credits and billing

  • Credits are consumed per API operation. Costs per endpoint are listed on the pricing page.
  • Credits do not roll over between billing months on paid plans.
  • Free tier credits (100/month) reset monthly and cannot be accumulated.
  • You are responsible for all charges incurred under your account and API key.
  • Payments are processed by PayPal. We do not store card or bank details on our servers.
  • Paid plans are billed monthly in advance. Downgrades take effect at the end of the current billing period.

4. Acceptable use

Your use of ApiOne must comply with our Acceptable Use Policy. In summary, you must not:

  • Resell or redistribute raw ApiOne data as a standalone data product.
  • Use the API to build a competing data enrichment service.
  • Attempt to reverse-engineer, scrape, or extract our underlying data sources.
  • Use the API in ways that violate applicable law, including data protection laws.
  • Share your API key with third parties outside your organisation.

5. API key and account security

You are responsible for keeping your API key confidential. If you believe your key has been compromised, rotate it immediately from your dashboard. We are not liable for unauthorised use of your key before you notify us.

6. Rate limits

We enforce rate limits per plan to maintain service quality for all users. Requests that exceed rate limits return a 429 error. Repeated abuse of rate limits may result in temporary or permanent account suspension.

7. Uptime and availability

We target 99.5% API availability. Planned maintenance will be announced at least 24 hours in advance via email. We are not liable for losses resulting from downtime, errors, or inaccurate enrichment results.

8. Termination

You may close your account at any time by emailing support@apione.store. We may suspend or terminate accounts that violate these Terms or our Acceptable Use Policy. Unused paid credits at termination are subject to our Refund Policy.

9. Limitation of liability

ApiOne is provided "as is" without warranties of any kind. To the maximum extent permitted by law, our total liability to you for any claim is limited to the amount you paid us in the 30 days preceding the claim. We are not liable for indirect, incidental, or consequential damages.

10. Changes to these terms

We may update these Terms from time to time. We will notify you by email at least 14 days before material changes take effect. Continued use of ApiOne after the effective date constitutes acceptance.
