Certify an artifact — no account required
Drop any file to compute its SHA-256 fingerprint and check the public registry. Sandbox certifications are test-mode only — rate-limited, limited retention, and clearly distinct from production certificates.
Anonymous sandbox includes a limited number of test certifications so you can see the full certification loop before creating an account.

What sandbox mode includes
Policy evaluation
Spend limits, merchant rules, and purpose restrictions are enforced in sandbox mode — same logic as production.
Signed receipts
Sandbox receipts are Ed25519-signed. Structure is identical to production — useful for integration testing.
Synthetic data generation
Generate and download certified synthetic datasets. Sandbox certificates are publicly verifiable.
Certificate verification
Verify any public artifact at /verify — no key needed, no account required.
Real payments
Sandbox mode does not trigger real charges. Use a live key on a paid plan for production transactions.
Registry listing
Sandbox artifacts are not listed in the public registry. Sign up for a free account to get registry presence.
When you're ready to go further
Sandbox outputs are ephemeral and scoped to test mode. Create a free account to get your own API keys, save history, list artifacts in the public registry, and access the full certification workflow.
