Siliq ECDH-PSI Simple Intersect
x402
Siliq ECDH-PSI Simple Intersect is a paid API for AI agents from compute.siliq.io, paid per call via x402, $0.02/call, status down (last checked 2026-09-15).
Computes the intersection of two sets using ECDH-based Private Set Intersection (PSI), revealing only common elements without exposing the full contents of either set.
Price / call$0.02

StatusDown
Output
Returns the set of elements that appear in both input sets (the intersection), computed via ECDH-based PSI protocol. Only matching elements are revealed; non-matching elements from either party remain private.
Example use cases
Example prompt
“I have two lists of customer email hashes — mine and a partner's — and I need to find which ones appear in both lists without either of us seeing the other's full list. Can you run a private set intersection using ECDH-PSI on these two sets?”
Technical details
Endpoint
POSThttps://compute.siliq.io/psi/intersect/simpleWhen to prefer
Use this endpoint when two parties need to find common elements in their respective datasets without revealing non-matching items to each other — ideal for privacy-preserving record linkage, secure data matching, or any scenario requiring set overlap computation under confidentiality constraints. Prefer over plaintext set comparison whenever data sensitivity or contractual privacy obligations are involved.
Side effects
- Mismatched element encoding between the two sets resulting in empty intersection
- Malformed or non-hashed inputs causing a 400 error
- Sets too large causing timeout or resource limits
- Invalid or missing set parameters returning a 422 validation error
- Network or payment (x402) authorization failure
