How this service works
Unique and sort a JSON list. Call when you need stable unique keys for agent set math. Returns sorted unique items and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
Output
Returns a sorted array containing only unique items from the input, plus an integer count of those unique items. No data is retained; processing is local and first-party only.
Example use cases
Deduplicating agent tool tags
“I have a list of tags collected from multiple agent runs and there are duplicates everywhere — can you deduplicate and sort this array so I get a clean canonical set: ["retry", "auth", "timeout", "retry", "auth", "parse"]?”
Stable key set for set math
“I need to build a stable unique sorted key list from this array before I do a set intersection: ["user:42", "user:7", "user:42", "user:99", "user:7"]. Can you run it through unique-sorted for me?”
Normalizing config option lists
“This config file has repeated environment names — can you deduplicate and sort this list so I end up with a clean unique sorted array: ["production", "staging", "development", "staging", "production"]?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/unique-sortedWhen to prefer
Choose this endpoint when you need a deterministic, stable, deduplicated and sorted version of a JSON array without any network lookups or external data retention — ideal for agent set math, canonical key normalization, or preflight deduplication steps at minimal cost ($0.001 USDC). Prefer it over client-side logic when you want a consistent, auditable transformation in a pipeline.
Side effects
- Non-array input returns a validation error
- Empty array returns an empty sorted list with count 0
- Malformed JSON body causes a 400-level error
- Payment not submitted or insufficient USDC balance causes a 402 Payment Required response
