**APIs profiled:** 5

Spire Global operates a constellation of more than 100 LEMUR nanosatellites collecting maritime AIS, aviation ADS-B, GNSS-RO weather profiles, and RF geolocation data, and offers Space Services for hosted payloads and managed satellite missions. Its data products are exposed as developer-friendly APIs: Spire Maritime 2.0 (now operated by Kpler) delivers vessel-tracking AIS through a GraphQL endpoint; Spire Aviation publishes REST APIs and real-time streams for flight metadata, live ADS-B tracking, historic positions, and event feeds; Spire Weather and Climate provides RESTful weather and ocean data APIs including 30 years of maritime weather history; and Spire Space Services exposes a developer portal for managed satellite operations. Spire's APIs are documented at product-specific subdomains and authenticated with API keys.
