FAQ
One API call to /v1/prove generates one proof. Each proof attests that a set of behavioral observations stays within your defined control limits. Verification calls (/v1/verify) are free and unlimited.
Yes. Verification is always free — both via the API and the open-source WASM verifier. This is by design: we want relying parties (auditors, clients, regulators) to verify proofs at zero cost.
No. SENTINEL uses a Prove-Don't-Share architecture: your raw observations are used to compute the EWMA and STARK proof in-memory, then discarded. The proof envelope contains only public inputs (observation count, final EWMA, control limits, pass/fail) — never individual observations.
No. SENTINEL uses STARK proofs (the same math used in blockchain scaling) but is designed for off-chain compliance. No blockchain, no smart contracts, no tokens. Just a fast API that generates cryptographic proofs.
API calls beyond your tier limit return a 429 status code. You can upgrade at any time. We'll never charge you without your explicit consent.
