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 three fields: 'items' (the deduplicated array), 'count' (the number of unique items), and 'schema' (a version identifier string 'delx/util-arr-uniq/v1'). Payment is processed via x402 protocol in USDC on Base or Solana at $0.001 per call.

Example use cases

Deduplicating product SKU lists

“I have a list of product SKUs from two merged catalogs and there are tons of repeats — can you remove all the duplicates and tell me how many unique SKUs remain? Here's the list: ['SKU-001','SKU-002','SKU-001','SKU-003','SKU-002'].”

Unique user IDs from event log

“I've got a raw event log with user IDs and many users appear multiple times. Can you give me a deduplicated list of just the unique user IDs from this array: [101, 202, 101, 303, 202, 404]?”

Cleaning up tag arrays before storage

“Before I save this post's tags to the database, can you strip out any repeated tags so I only store unique ones? The tags are: ['javascript','api','javascript','agent','api','tools'].”

When to prefer

Choose this endpoint when you need a simple, trustless, pay-per-call array deduplication with no signup or API key overhead, especially in agent pipelines that already use x402/USDC microtransactions on Base or Solana. It's ideal for lightweight data-cleaning steps inside automated workflows where you want verifiable, metered utility calls rather than spinning up your own deduplication logic.

Side effects

Missing or non-array 'items' field — likely returns a 4xx validation error
Empty array input — returns count 0 and empty items array
Payment failure via x402 — returns HTTP 402 if USDC payment is not accepted
Malformed JSON body — returns 400 bad request
Network timeout — transient 5xx error
