# API Workflows (/docs/api-workflows)



These workflows guide you through combining Global Fishing Watch APIs — the [4Wings API](/docs/v3/4wings), [Vessels API](/docs/v3/vessels), and [Events API](/docs/v3/events) — to build practical use cases for analyzing fishing effort, identifying vessels, and reviewing their event history.

Each workflow walks through a real scenario end to end, from defining a region of interest to generating an analysis for enforcement or compliance authorities.

* **[Analyzing Apparent Fishing Effort in a Region and Retrieving Vessel Details](/docs/api-workflows/analyzing-fishing-effort-in-a-region)** — Query fishing effort for trawlers in a region and retrieve vessel details (4Wings → Vessels).
* **[Analyzing Apparent Fishing Effort for Trawlers in an EEZ](/docs/api-workflows/monitoring-trawlers-in-an-eez)** — Identify trawlers in an EEZ, retrieve their identity, and check port visits and encounters (4Wings → Vessels → Events).
* **[Analyzing a Fleet (a Group of Vessels)](/docs/api-workflows/analyzing-a-fleet)** — Track a fleet of longliners, retrieve vessel details, and detect fleet activity across multiple vessels (4Wings → Vessels → Events).
