Ethereal Exploration Guild
Ethereal Exploration Guild (EtherealX) is an Indian spacetech company founded in 2022 in Bengaluru by Manu J. Nair, Prashant Sharma, and Shubhayu Sardar, building fully reusable medium-lift launch vehicles. Its lead product, the Razor Crest Mk-1 (RCM1), targets roughly 25 tons to low Earth orbit with high launch cadence, up to 16 orbit insertions per flight, and 72-96 hour turnaround. The company has manufactured its 80kN reusable upper-stage engine (Pegasus) using a proprietary Full Flow Segregated Cooling Cycle (FFSCC) and operates a large private rocket testing facility in Cuddalore, Tamil Nadu. EtherealX has raised on the order of $26M across multiple rounds, including a Series A in December 2025. The company offers launch services rather than any developer-facing API or platform.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Ethereal Exploration Guild the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Ethereal Exploration Guild scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
