# Kayhan Space — Satcat > Kayhan Space builds autonomous spaceflight-safety and space-traffic-coordination technology for satellite operators. The Satcat Service API (OpenAPI 3.1, OAuth2 client-credentials) exposes space situational awareness and collision avoidance: conjunction data messages (CDMs), events and mitigation intent, on-orbit screening, ephemeris and TLE catalog services, state vectors and covariance, propagation, orbit determination, maneuver design, launch/LEOP screening, and collision-avoidance (COLA) planning. This llms.txt was generated by the API Evangelist enrichment pipeline from the provider's public OpenAPI and docs (no /llms.txt is published by the provider as of 2026-07-19). ## API - [Satcat Service API docs](https://docs.satcat.com): developer documentation for authenticated and public endpoints - [Interactive API reference (OpenAPI UI)](https://api.satcat.com/docs) - [OpenAPI 3.1 specification](https://api.satcat.com/openapi.json) - Base URL: https://api.satcat.com/api/satcat - Auth: OAuth2 client credentials; token endpoint https://api.satcat.com/api/satcat/oauth/token; send `Authorization: Bearer ` ## SDKs - [Python SDK `satcat` (PyPI)](https://pypi.org/project/satcat/) — `pip install satcat`; source at https://gitlab.com/kayhan-oss/satcat-sdk (Apache-2.0) ## Products - [Satcat](https://kayhan.space/products/satcat): space situational awareness and traffic-coordination platform - [Dynamics](https://kayhan.space/products/dynamics): astrodynamics estimation and orbit-simulation engine ## Specs & artifacts (this repo) - OpenAPI: openapi/kayhan-space-satcat-openapi-original.json - Authentication: authentication/kayhan-space-authentication.yml - OAuth scopes: scopes/kayhan-space-scopes.yml - Conventions: conventions/kayhan-space-conventions.yml - Error catalog: errors/kayhan-space-problem-types.yml - Data model: data-model/kayhan-space-data-model.yml - Conformance: conformance/kayhan-space-conformance.yml - Lifecycle: lifecycle/kayhan-space-lifecycle.yml - Agent skills: skills/_index.yml ## Docs - [Key concepts](https://docs.satcat.com/key-concepts/) - [Data standards](https://docs.satcat.com/data-standards/) (CCSDS CDM, TLE, reference frames, risk metrics) - [SDK configuration](https://docs.satcat.com/sdk/configuration/) ## Support & status - [Status page](https://status.satcat.com) - [Discord community](https://discord.gg/2AuzMTBuJM) - Email: support@satcat.com - [GitHub org](https://github.com/Kayhan-Space)
