Yes. The SpaceNexus API provides programmatic access to launch schedules, company profiles, funding rounds, market intelligence, and news feeds. API keys are managed through the developer portal; a free account gets a key for the free endpoints. The REST API includes rate limiting, versioned endpoints (v1), and returns JSON responses. Full API access, every endpoint, is included with the Professional plan.

Security is a top priority. All traffic is encrypted via HTTPS with strict security headers. Authentication uses bcrypt-hashed passwords with email verification and CSRF protection. We conduct regular security audits, implement rate limiting on all endpoints, and use input sanitization throughout the platform. You can delete your account and all associated data at any time.
