What Launch Library 2 (BYOK) is for

Launch Library 2 (BYOK) lets an AI assistant read your own Launch Library 2 data through the Launch Library 2 API with a key you supply (Launch Library 2 API key). Read-only: 11 tools (list_upcoming_launches, list_previous_launches, get_launch, list_agencies, list_astronauts, list_upcoming_events, list_space_stations, list_expeditions, list_launch_pads, list_launcher_configurations, get_api_throttle). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to ll.thespacedevs.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Launch Library 2. Launch Library 2 and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

  • "What rocket launches are coming up in the next two weeks?"
  • "Which SpaceX launches happened this year?"
  • "Show details of launch 7530ff92-eab0-4c8b-8a8b-f3ac2a3bd5a1"
  • "Which agencies are active in launching rockets, starting with NASA?"
  • "Which astronauts are in space right now?"
  • "What spacewalks or dockings are scheduled soon?"

What it does

  • list_upcoming_launches: List upcoming rocket launches soonest first, with status, launch window, provider, rocket, mission, orbit and pad. Filter by provider, rocket, crewed or time window.
  • list_previous_launches: List past rocket launches, newest first by default, with outcome, provider, rocket, mission and pad. Filter by provider, rocket, year or time window.
  • get_launch: Get one launch by its ID with status, window, provider, rocket, mission, pad, failure reason, video and info links and timeline.
  • list_agencies: List space agencies and launch companies with type, country, founding year, administrator and description. Search by name.
  • list_astronauts: List astronauts with status, agency, nationality, age, flights and whether they are in space now. Search by name.
  • list_upcoming_events: List upcoming space events such as dockings, spacewalks, tests and landings with date, type and webcast flag.
  • list_space_stations: List space stations with status, owner type, founding and deorbit dates, orbit and description. Can show only those with crew on board.
  • list_expeditions: List space station expeditions (ISS and others) with start and end dates and the station. Can show only active ones.
  • list_launch_pads: List launch pads with location coordinates, country and the number of launches from each. Search by name.
  • list_launcher_configurations: List rocket configurations (Falcon 9, Ariane 6 and others) with manufacturer, reusability and links. Search by name.
  • get_api_throttle: Show how many Launch Library 2 requests your key has used in the current period and the limit.

BYOK key

You bring your own Launch Library 2 Launch Library 2 API key (https://thespacedevs.com/llapi). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to ll.thespacedevs.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

Live from the Launch Library 2 API (ll.thespacedevs.com) with a BYOK key; documentation: https://ll.thespacedevs.com/docs/. Endpoints checked against that documentation on 2026-10-16.

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Launch Library 2.
