Changes coming to ASF SearchAPI
May 9, 2025
On May 21, 2025, an update will be delivered to the ASF API that will result in a 30-second timeout on searches when using SearchAPI. This will affect large list searches and Vertex searches set for 5,000 results.
To avoid this time limit on large searches, we recommend using the asf_search Python package, which will not be affected.
Please contact [email protected] if you have any questions.
