How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the compacted array (items), the count of remaining items (count), the number of removed items (removed), and a schema identifier string (schema: 'delx/util-arr-compact/v1').
Example use cases
Pipeline data cleaning before storage
“I have an array coming out of my scraper that has nulls and empty strings mixed in: [42, null, 'hello', false, 99, '', 7] — can you compact it and tell me how many junk values got stripped?”
Sanitizing user-submitted tag lists
“Users submitted a tag list that has empty entries and false values in it: ['travel', null, 'food', '', false, 'tech'] — clean it up so I only have the real tags left.”
Preparing numeric data for calculation
“Before I run stats on this dataset, I need to remove all the null and falsy placeholders from this array: [10, 0, null, 55, false, 22, null, 8] — give me just the valid numbers and tell me how many were removed.”
