How this service works
JSON Array Dedupe: JSON Array Dedupe removes duplicate JSON array values while preserving first occurrence from bounded caller-supplied values without an external provider. Call JSON Array Dedupe before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Array Dedupe as versioned deterministic JSON. Price: $0.001 USDC via x40…
Output
Returns a versioned deterministic JSON object containing the deduplicated integer array (preserving first-occurrence order), counts of unique vs. duplicate values, and normalized output conforming to a versioned result contract.
Example use cases
Clean up duplicate order IDs
“I have a list of order IDs that may contain duplicates: [1021, 1034, 1021, 1099, 1034, 1200]. Can you deduplicate them and give me back just the unique IDs in the order they first appeared?”
Normalize sensor readings before processing
“Before I send this batch of sensor readings to our analytics pipeline, can you remove any duplicate integer values from this array: [42, 7, 42, 15, 7, 99, 15, 3]?”
Dedupe tag IDs before downstream API call
“I'm about to post a list of category tag IDs to our CMS but I think there are repeats — can you clean up [5, 12, 5, 8, 12, 20, 8, 33] and give me only the unique ones, preserving the original order?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/json-array-dedupeWhen to prefer
Use this endpoint when an agent needs a lightweight, stateless, pay-per-call deduplication of integer arrays (up to 256 items) before handing structured data to a downstream tool with a strict contract. Prefer it over custom deduplication logic when you need a versioned, auditable result contract with counts included in the response.
Side effects
- Array exceeds 256-item maximum — request rejected
- Non-integer values in the array — schema validation failure
- Empty array input — may return empty result or validation error
- Malformed JSON body — parse error response
- Payment not included or insufficient — 402 Payment Required
