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 a count of unique items, an array of those unique items representing the mathematical union of inputs A and B, and a schema identifier string ('delx/util-set-union/v1').
Example use cases
Merging tag lists from two sources
“I have two lists of tags from different systems — ["billing","urgent","vip"] and ["urgent","support","refund"] — can you merge them into one deduplicated list of all unique tags?”
Combining user ID sets
“I've got two sets of user IDs: [101, 202, 303] from one campaign and [202, 404, 505] from another. Can you give me the full set of unique user IDs across both?”
Finding all distinct categories
“I have product categories from two different catalogs — ["electronics","books","clothing"] and ["books","toys","clothing","sports"] — merge them into one list with no repeats.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/set-union?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call set union operation with no setup, no API key, and verifiable USDC-based payment via x402. Ideal for agents that occasionally need set operations without spinning up data-processing infrastructure.
Side effects
- Malformed input (non-array values for a or b) may result in a 400 error
- Payment failure via x402 protocol will block execution
- Empty arrays return an empty union with count 0
- Non-homogeneous array types may produce unexpected deduplication behavior
