KOSMOLAB SPACE API
A public, read-only REST API over the launch windows, providers, hardware catalog and matchmaker that power the platform. Build tools, dashboards and integrations on live space-industry data.
Base URL & conventions
https://kosmolab.space/wp-json/- All endpoints are GET and return JSON. Public catalog reads need no authentication.
- Please cache responses and keep request rates reasonable — the public tier is shared and rate-limited.
- Data is sourced from The Space Devs Launch Library 2 and from suppliers. It may be delayed or change without notice — verify critical figures at the source. See Terms.
- Writing data (adding products, sending RFQs) is done through your account, not this public API.
