Read-only space industry data: launches, slips, funding, companies, space weather, Moon race, jobs.
Scored across 14 tools
Most tools have clearly distinct purposes, but there is some overlap within funding (company_lookup, funding_round_history, recent_funding_rounds) and launch data (launch_ledger_record, launch_slips, next_launches). Descriptions clarify scopes, but an agent could still confuse full history vs recent summaries.
All tool names use consistent snake_case and are descriptive noun phrases. However, they do not follow a verb_noun pattern (e.g., search_site is the only verb-first name), so there is a minor deviation from the ideal convention.
14 tools is well within the ideal 3–15 range for a data platform. Each tool serves a distinct data need (companies, funding, launches, promises, jobs, weather, search, datasets), so the count feels earned and not bloated.
The surface covers core space industry data well: company profiles, funding rounds, launch schedules and slips, promise tracking, jobs, space weather, and bulk datasets. Minor gaps exist (e.g., dedicated rocket/launch-site lookup or historical launch lists), but search_site and dataset_links can work around them.
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.
Inputs: query (required), limit.
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.
Inputs: dataset.
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.
Inputs: limit, since, stage, until, +4 more.
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.
Inputs: kind, limit, since, launch, +4 more.
How often launches fly on time: the share of flown launches that lifted off within 1 day and within 7 days of the first firm date on record, with mean and median delay, grouped by provider, vehicle or launch site.
Inputs: name, limit, group_by.
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.
Inputs: limit, rocket, provider, real_moves_only.
The US vs China Moon race tracker: milestones demonstrated on both 8-rung ladders (crewed landing and sustained presence), who leads each, the projection call with its date bands, official targets and the next uncrewed landing attempt.
Inputs: no named parameters.
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.
Inputs: site, limit, rocket, country, +2 more.
Needs a SpaceNexus API key (a free key is enough). Entries from the SpaceNexus Promise Ledger: dated public commitments about spaceflight by agencies, companies and executives, each with the verbatim quote, who said it and when, the deadline as stated and normalised, the status shown today, the outcome and its source, and every later revision. Filter by party, status, claim type or words; page with offset.
Inputs: limit, party, query, offset, +2 more.
Closed private funding rounds into space companies in the last 90 days, newest first, with amount (null when undisclosed, never estimated), stage, investors, how the round is evidenced and its source link.
Inputs: days, limit, stage, company, +1 more.
Search spacenexus.us: companies, rockets, launches, launch sites, guides, charts, Moon missions, funding rounds and analysis. Returns titles, one-line descriptions and the canonical URL of each page.
Inputs: query (required), limit.
How many open roles the SpaceNexus jobs board lists right now (mirrored daily from employers' careers pages), how many employers are hiring, how many roles are new this week or remote, and optionally one employer's open roles.
Inputs: company.
Needs a SpaceNexus API key whose owner has SpaceNexus Research (the Space Score history is a Research product). One company's daily Space Score readings for up to 365 days: score, rank, the change from the previous reading, large moves flagged, and why a reading moved where the stored inputs can say. The current score stays free in company_lookup.
Inputs: company (required), days.
Current geomagnetic Kp and NOAA G-scale, solar wind speed, density and Bz, the NOAA 3-day flare outlook and flares in the last 14 days, with a plain-language read for satellite operators. NOAA SWPC and NASA DONKI data.
Inputs: no named parameters.
