By subscribing to or using any Aethar service ("Services"), you agree to these Terms of Use. If you do not agree, do not use the Services.
Aethar provides production-ready APIs and developer tools for workforce data, e-invoicing compliance, and related domains. Specific capabilities and data sources vary by product and are described in each product's documentation.
You may use API responses to build applications, dashboards, reports, and internal tools. You may cache responses locally to reduce redundant calls. You may display data publicly, provided attribution requirements are met. You may not resell, redistribute, or sublicense raw API responses as a standalone dataset. You may not scrape, bulk-download, or systematically extract the full dataset. You may not misrepresent the data source. You may not use the API in any way that violates applicable law.
When displaying data obtained from Aethar services to end users, you must include appropriate attribution to the underlying data sources where required. Specific attribution requirements are documented per product.
Rate limits are enforced per API key and vary by subscription tier. Exceeding your plan's rate limit will result in HTTP 429 responses. Sustained abuse or circumvention of rate limits may result in suspension.
Aethar services aggregate and serve data on a best-effort basis. We do not guarantee the accuracy, completeness, or timeliness of any data returned. The Services may not be available without interruption. You are responsible for validating data suitability for your use case.
We aim for high availability but do not guarantee specific uptime percentages or response times. In the event of a service disruption, we will make reasonable efforts to initiate recovery procedures as soon as practicable. Planned maintenance (database migrations, infrastructure upgrades): announced in advance via status.aethar.dev. Emergency deployments (security patches, critical fixes): may occur without prior notice. Typical interruption: under 60 seconds. No SLA-based credits or refunds are offered. Service status and incident history are available at status.aethar.dev.
To the maximum extent permitted by applicable law, Aethar shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the API. Total aggregate liability shall not exceed the fees paid in the 3 months preceding the claim.
All billing, payments, and subscription management are handled by Paddle.com Market Limited ("Paddle"), who acts as Merchant of Record. Aethar does not process payments directly. Billing disputes should be directed to Paddle support or to [email protected]. See our Refund Policy for details on cancellations and refunds.
Aethar reserves the right to suspend or terminate your API access at any time for violation of these Terms, abuse of rate limits, or non-payment or failed billing (handled by Paddle). You may cancel your subscription at any time through the Aethar Console (console.aethar.dev) or via your Paddle receipt email.
We may update these Terms at any time. Material changes will be communicated via the API documentation or Aethar Console. Continued use after changes constitutes acceptance.
These Terms are governed by the laws of the Republic of Poland and the European Union. Any disputes shall be subject to the exclusive jurisdiction of the courts in Poland.
