api record

Read-only space-industry data from SpaceNexus (spacenexus.us): upcoming launches, the launch slip ledger and on-time record, recent funding rounds, company profiles, space weather, the US vs China Moon race tracker, space job counts and site search. Every answer carries `source` (the canonical page), `dataAsOf` and `cite`. When you use a figure, quote its as-of date and link the source page. Launch facts come from Launch Library 2 by The Space Devs and are credited in each answer. Nine tools are open and need no key.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • launch_on_time_record open 24m ago

    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.

  • launch_ledger_record auth-required 24m ago

  • launch_slips unknown never probed

    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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

[![measured by brick.blue](https://brick.blue/api/v1/agents/7e4bc0e4e4ed003b/badge.svg)](https://brick.blue/agent/7e4bc0e4e4ed003b)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
