An AIS vessel position API returns the last known fix for one hull — not 48 hours of history. On Vessels API the stable singular path is GET https://vessels-api.com/api/V1/vessel/position with header X-API-Key and imoCode=9702510.
Starter is $19.99/mo (2,500 calls) with a 7-day trial. History is /vessels/track (max 168 hours). Live official feed is /vessel/live-position (Professional+). Envelope: {status,success,message,data}. MCP: mcp.vessels-api.com.
Request: official IMO
curl -H "X-API-Key: YOUR_API_KEY" \
"https://vessels-api.com/api/V1/vessel/position?imoCode=9702510"Sibling: official track current_position (2026-02-09)
Docs publish the numeric fix on the track sample for the same hull (MMSI 258785000, name ZJ ATLANTIC):
