Calculation platform with API
A standalone platform for astronomical calculations with an API for developers and companies, with key management, webhooks and billing.
The situation
Precise calculations often depend on third-party libraries. A paid service for business customers also needs legally sound acceptance of terms, billing and backups.
The idea
The engine runs without third-party libraries, and its accuracy is measured against independent references. Where the legal situation or country is unclear, the platform blocks by default.
How it is built
- Every response states the method, the accuracy and a checksum of the dataset.
- Webhooks, an API key lifecycle and an OpenAPI description; it can also run on your own infrastructure.
- Country register with server-side blocks. Terms are confirmed before first use and archived unchangeably.
- Daily encrypted off-site backup and a monthly restore test.
Documented figures
- 0.45″largest deviation of the Moon against JPL DE440 over 2,050 points in time (July 2026)
- 19tables in the monthly restore test (July 2026)
Status
In production since July 2026. Paid self-service stays closed until legal and tax sign-off.
