Error Handling

Common Errors

Error	Cause	Solution
`No results found`	Search too specific	Broaden search terms or remove filters
`Invalid tag_names`	Malformed tag list	Use comma-separated values without spaces
`Invalid filter_value`	Wrong value for filter_variable	Check valid values for the filter type
`Limit exceeds maximum`	limit > 1000	Use limit ≤ 1000 and pagination

Best Practices

Start Broad

Begin with general terms and progressively add filters

Use Tags Effectively

Combine geographic, frequency, and topic tags for precision

Sort by Popularity

Popular series are often the most reliable and widely used

Exclude Discontinued

Add exclude_tag_names: "discontinued" for active series only
