How this service works
Weekly port congestion figures for one port from Portcast's public port page: median waiting time (days), average vessels waiting per day, congestion category and week-on-week change. Free public page data (not the paid API), and only for ports Portcast publishes; the slug is the port name in lowercase, e.g. ako or long-beach.
Output
A JSON object containing the port name and slug, the week covered, the median vessel waiting time in days, the average number of vessels waiting per day, a congestion category label (e.g. 'low'), a flag indicating long-tail congestion, and the percentage change in congestion from the previous week, along with the source URL and the timestamp when the data was checked.
Example use cases
Pre-shipment port congestion check
“Before we book our container shipment through Long Beach, can you pull the latest congestion data — median wait time, how many ships are sitting there daily, and whether things are improving or getting worse compared to last week?”
Supply chain disruption monitoring
“I need to keep an eye on port congestion at Singapore this week — tell me the congestion category, the average number of vessels waiting per day, and the week-on-week change so I can flag any issues to our logistics team.”
Multi-port trade route comparison
“Can you look up the port congestion figures for Rotterdam? I want to know the median waiting time in days, the congestion level category, and whether congestion went up or down from the previous week.”

Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/logistics/port-congestion-index?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, free-tier weekly port congestion snapshots for ports covered by Portcast's public pages. It is ideal for supply chain monitoring, pre-shipment planning, or enriching logistics dashboards without needing a full paid Portcast API subscription. Prefer alternatives if you need real-time (sub-weekly) vessel data, ports not listed on Portcast's public congestion page, or historical time-series data beyond weekly snapshots.
Side effects
- Port slug not found or not published by Portcast — returns an error or empty result
- Invalid slug format (e.g. uppercase or spaces) — request may fail or return no data
- Portcast public page structure changes — scrape may break and return stale or missing data
- Network timeout to Portcast's public page — upstream fetch failure
- Port exists but Portcast has not published recent congestion data for that week
