SpaceTradersAPI
SpaceTraders is a fully playable, headless space-trading MMO with no first-party client — players POST to /v2/register to receive an agent and a bearer token, then automate fleets, markets, and exploration entirely through the REST API. The live API root confirms the server is online with hundreds of active agents and tens of thousands of ships, and returns a wildcard Access-Control-Allow-Origin header, making it usable straight from a browser; the stored "OAuth" auth was stale — access is a per-agent bearer token from registration, not an OAuth authorization flow.
