Delx Set Intersect is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Computes the intersection of two arrays, returning only the elements present in both lists along with the count.

How this service works
Set intersection of two lists. Call when you find shared agent tags/IDs. Returns intersection 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 the list of elements that appear in both input arrays (the intersection) and an integer count of how many shared elements were found. No data is retained server-side; computation is local and first-party.
Example use cases
Shared agent tags across pipelines
“I have two agent pipelines each with their own tag lists — pipeline A has ["billing", "kyc", "fraud", "onboarding"] and pipeline B has ["fraud", "kyc", "payments"] — tell me which tags are active in both.”
Deduplicating common user IDs
“Given these two user ID lists from different data sources — ["u1","u2","u3","u7"] and ["u3","u5","u7","u9"] — which IDs appear in both so I know which users exist in both systems?”
Matching feature flags across environments
“I have feature flags enabled in staging: ["dark-mode","new-checkout","beta-api"] and in production: ["new-checkout","analytics-v2","dark-mode"] — what flags are on in both environments?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/set-intersectWhen to prefer
Choose this endpoint when you need a fast, stateless, paid-per-call set intersection without building custom logic — especially useful in agent pipelines that need to find shared tags, IDs, or labels across two collections. Prefer it over manual filtering when you want a reliable, auditable micro-utility with no server-side data retention and a predictable $0.001 USDC cost per call.
Side effects
- Missing or non-array input for field 'a' or 'b' returns a validation error
- Empty arrays on either side return an empty intersection with count 0
- Payment failure via x402 (insufficient USDC balance or network issue) results in a 402 response before computation
- Duplicate handling within a single array may affect intersection count depending on implementation
