Xairos Systems is a Techstars-backed company building quantum time transfer (QTT) technology - a space-based, quantum-resilient global timing and synchronization system positioned as a secure alternative to GPS for positioning, navigation, and timing (PNT). The company targets sub-nanosecond accuracy while mitigating GPS jamming and spoofing, serving critical infrastructure sectors such as transportation, finance, data centers, and power grids. Xairos publishes no first-party developer API, but its site ships an llms.txt and a live Wix Site MCP endpoint for agentic access to public site content.
Xairos is profiled on the APIs.io network. Tagged areas include Company, Quantum, Timing, Synchronization, and PNT.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/xairos: open an issue to ask a question, or submit a pull request to add artifacts.
