Terms of Service

Last updated: 7 July 2026

1. Agreement

By creating an account or using Astronomy Core (REST API, MCP server, dashboard, or OAuth connections), you agree to these Terms. If you do not agree, do not use the service.

2. Service description

Astronomy Core provides astronomical and astrological computation APIs and MCP tools. Outputs are structured JSON for software integration — not professional advice (medical, legal, financial, or personal counselling).

3. Accounts and credentials

You must provide accurate registration information and keep credentials secure.
API keys and OAuth-issued keys are personal to your account. You are responsible for usage under your keys.
Do not share keys in public repositories, client-side apps, or untrusted third parties except via supported OAuth connectors you explicitly authorize.
We may suspend or revoke access for abuse, quota violations, or security risk.

4. OAuth connections

Connecting Claude, ChatGPT, or Perplexity grants that platform access to call Astronomy Core with your account entitlements. Re-authorizing may replace an existing connection and invalidate prior sessions for that app. Revoke access anytime from your dashboard.

5. Acceptable use

No attempts to bypass authentication, quotas, or module gates.
No automated registration abuse or credential stuffing.
No use that violates applicable law or infringes third-party rights.
Respect rate limits and tier entitlements.

6. Tiers, quotas, and changes

Free and paid tiers may have different module access and quotas. We may change limits, pricing, or features with reasonable notice where required. Continued use after changes constitutes acceptance where permitted.

7. Intellectual property

We retain rights in the platform, documentation, and branding. You retain rights in your application code. API response data is licensed for your use in your applications subject to these Terms.

8. Disclaimers

The service is provided “as is” to the extent permitted by law. Computational results depend on input parameters and documented algorithms; we do not guarantee suitability for any particular purpose.

9. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, or consequential damages, or for loss of data or profits arising from use of the service. Aggregate liability is limited to fees paid in the twelve months preceding the claim, or zero for free-tier users.

10. Termination

You may stop using the service and delete API keys at any time. We may terminate or suspend accounts for breach of these Terms. Provisions that by nature should survive termination (liability limits, governing law) survive.

11. Governing law

These Terms are governed by applicable law in the jurisdiction where Astronomy Core is established, without regard to conflict-of-law rules.
