Poseidon AIS

Real-time and historical global AIS vessel-position dataset exposed through a developer-oriented REST API: live vessel positions with search, identify, in-area and radius scans, bulk lookups and a full vessel-database dump, plus per-vessel historical track retrieval gated by subscription tier (30 days, 365 days or extended history). The response surface is stated to be the full upstream AIS message field set rather than a trimmed vendor subset. Derived products positioned on the site include ETA-versus-actual deviation alerts, congestion prediction, AIS-gap and dark-fleet detection, vessel identity-change tracking, and pattern-of-life datasets

Dataset card

Type: not stated
Format: Tabular / JSON — REST API returning a JSON envelope with credit cost and remaining quota in headers, X-API-Key authentication, SDK-style examples in three languages
Volume: Headline coverage figures are not reliably readable on the page — the counter tiles render as unpopulated placeholders (0.00M+ vessels, <0ms latency, 0D history, 0.0% uptime), and the search-index summary of the same page cites 400,000+ vessels tracked and 1.97M+ vessels in the system. Treat vessel coverage as unverified pending direct confirmation; what is concrete is 11 live endpoints with 15 more on a stated roadmap. Request the true vessel count, message ingestion rate and retained-history size
Users: Not yet established — the product is labelled early access v0.2 and beta, with access granted by request form ('we'll set up your account within 24 hours') rather than open signup, so the customer base is small and hand-onboarded
History: not stated
Update frequency: not stated
Growth: Active but pre-production-maturity — explicitly marked 'EARLY ACCESS v0.2', 'API SURFACE EVOLVING' and 'BETA', with 11 live endpoints against 15 on the roadmap, so the data product is shipping but incomplete
Launched: Est. ~2025-2026 (a v0.2 early-access version label, an evolving API surface and a beta banner place the launch very recently; no founding date or corporate registration is published on the site)
Delivery: not stated
Entity mapping: not stated
Sample: not stated
Point-in-time: not stated
Licence: not stated
