company_lookup

Public profile facts for a space company: what it does, sector, country, headquarters, founding year, public or private, ticker, funding and last round as shown on its profile (for a listed company the funding figure is the private rounds it raised before listing, and fundingBasis says which rule applies), and its Space Score when it is ranked.

read-only

Argument	Type	Description
limit	integer	How many matching companies to return (1 to 5).
query*	string	Company name, profile slug or stock ticker, e.g. "Rocket Lab", "rocket-lab" or "RKLB".

dataset_links

Needs a SpaceNexus API key (a free key is enough). The bulk SpaceNexus datasets: for each one its CSV and JSON download links, what it holds, its columns, its licence statement, its DOI when minted and the page that shows it, plus the Promise Ledger CSV. The downloads themselves need no key.

funding_round_history

Needs a SpaceNexus API key on the Professional or Research plan. The full published history of private funding rounds into space companies, not only the last 90 days: date, amount (null when undisclosed or stated only approximately, never estimated), series and round type, pre- and post-money valuation where the source names the basis, lead investor and every listed investor, how the round is evidenced and its source link. Filter by company, investor, stage, dates and amount; page with offset.

limit	integer	How many rounds to return (1 to 25).
since	string	Rounds dated on or after this day (YYYY-MM-DD).

launch_ledger_record

Needs a SpaceNexus API key (a free key is enough). The full Launch Ledger record: every launch date change our ledger holds since recording began, one row per launch per UTC observation day, with the observation fields (live or catch-up, the catch-up reason, Launch Library 2's last-updated time), both dates at their precision and its basis, the size and kind of the move, and whether it counts as a slip. Filter by launch, provider, rocket, observation, kind and day; page with offset. The same rows as the free launch-slips dataset.

read-only

Argument	Type	Description
kind	string	Only this kind of move: slip, pull-in, adjust, firmed, loosened or placeholder.
limit	integer	How many rows to return (1 to 25).
since	string	Only changes observed on or after this UTC day (YYYY-MM-DD).
launch	string	One launch: its name or mission (substring, e.g. "Starship Flight 14") or its Launch Library 2 id.
offset	integer	Rows to skip, for paging (0 to 10000).
rocket	string	Only launches of this rocket (substring).
provider	string	Only launches by this provider (substring or common short name, e.g. "ULA", "CASC").

launch_on_time_record

read-only

Argument	Type	Description
name	string	Only groups whose name contains this text, e.g. "SpaceX" or "Falcon 9".

  "additionalProperties": false
}

launch_slips

Recent launch date changes as the SpaceNexus slip ledger recorded them (old date, new date, size of the move, kind of move), with totals since recording began and the provider scorecard once the ledger is large enough. Each change carries observation: live (our sync saw it when it happened) or catch-up (our sync only caught up late, so observedAt is when we saw it, not when it changed). Caught-up changes are returned apart in caughtUpChanges and never counted in the summary figures.

read-only

Argument	Type	Description
limit	integer	How many recent date changes to return (1 to 25).
rocket	string	Only moves of this rocket (substring).
provider	string	Only moves by this provider: a name or common short name (ULA, ISRO, CASC).
real_moves_only	boolean	Leave out placeholder moves (a "NET 2026" style date firming or rolling); keep slips, pull-ins and adjustments.

next_launches

Upcoming orbital launches from the SpaceNexus manifest (the next 50 scheduled), filterable by provider, rocket, launch site and country. Each launch has its NET date and precision, status, the date changes our ledger recorded, and its page URL. realSlips and otherDateMoves count only changes our sync saw when they happened; caughtUpDateMoves counts changes it only caught up with late (made earlier, on a day we do not know), which are never counted as slips.
