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.

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_slips reads open 2h ago

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.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 7e4bc0e4e4ed003b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/7e4bc0e4e4ed003b/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

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

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ 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

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.
