Delx Commerce — JSON Array Intersection
x402
Delx Commerce — JSON Array Intersection is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Computes the intersection of two integer arrays, returning shared elements and their count, with cryptographic evidence of no data retention.

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 intersection items as an integer array, the count of shared elements, a status field ('pass'), and an evidence block confirming no data was retained (retained: false), the SHA-256 hash of the input, and that zero external calls were made. Schema is labeled 'delx/util-json-array-intersection/v1'.
Example use cases
Filtering shared product IDs
“I have two lists of product IDs — one from our warehouse inventory and one from last week's orders. Can you find which product IDs appear in both lists? Warehouse: [101, 202, 303, 404, 505] and Orders: [202, 303, 606].”
Matching user cohort overlap
“I've got two groups of user IDs — group A is [10, 20, 30, 40, 50] and group B is [20, 40, 60, 80]. Which user IDs are in both groups, and how many overlap?”
Finding common feature flags
“Compare these two integer feature-flag ID sets and tell me which flags are active in both: set one is [1, 3, 5, 7, 9] and set two is [3, 6, 7, 8, 9].”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/json-array-intersection?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a trustless, verifiable set intersection computation on two integer arrays with cryptographic proof of no data retention — ideal for privacy-sensitive agent workflows or when auditability of the computation is required. At $0.001 USDC per call with no signup, it suits lightweight agent pipelines that need deterministic utility math without spinning up infrastructure.
Side effects
- Arrays exceeding 256 items will be rejected
- Non-integer array elements will fail schema validation
- Missing 'left' or 'right' fields will cause a bad request error
- Payment failure via x402 will prevent execution
- Malformed JSON body will return a parse error
Input

| Field | Type | Description |
|---|---|---|
| left | array | Left supplied to JSON Array Intersection; used only for this bounded calculation and processed in memory without retention. |
| right | array | Right supplied to JSON Array Intersection; used only for this bounded calculation and processed in memory without retention. |
