Pay-per-Seal: one post-quantum (Dilithium-3) provenance seal + a self-contained ML-DSA-65/Dilithium-3 (NIST FIPS 204) signature — drand-timestamped, with on-chain anchoring attempted per call and reported in the response...
Verifiable Random shuffle — a uniform Fisher-Yates permutation bound to a future drand round the server waits for (typically 3-6s) and verifies locally, with original indices and a reproducible proof transcript.
Breached password check: is this password in known data breaches, and how often? Send only the SHA-1 hash (never the password); just the first 5 characters reach Have I Been Pwned (k-anonymity). Up to 50 hashes per call.
