Try CertifiedData live
Three pillars. One proof system. Sign an AI decision, run an agent-commerce receipt, and generate a certified dataset — in about three minutes, without logging in.
Certification is the cryptographic layer underneath all three. How certification works →
Decision Ledger
Sign, hash, and verify an AI decision — in about 45 seconds.
See exactly how an AI decision gets a tamper-evident record your auditor can verify — without any integration work.
- →Sign a real decision from a sample payload (loan, claim triage, agent action) in one click
- →Get back a verifiable record: SHA-256 hash, Ed25519 signature, key ID, canonical payload
- →Verify the signature yourself — no login, no API key, no SDK
- →30 signed demos per minute per IP — plenty of room to iterate
- ✓1,000 signed decisions per month on the free plan
- ✓Permanent public verification URL for every record
- ✓Real API key · dashboard history · audit-ready exports
Agent Commerce
Run a policy-aware transaction and inspect the signed receipt.
See what a machine-readable, signed receipt looks like when an agent pays for something — and what gets enforced before the money moves.
- →Run a sandbox transaction end-to-end: authorize, execute, receive a signed receipt
- →Inspect the policy decision that gated the transaction — why it ran or why it didn't
- →Verify the receipt signature against the published public key
- →3 ephemeral sandbox keys per 24h · 24h TTL · no per-transaction cap once keyed
- ✓Unlimited sandbox transactions on any issued key
- ✓Save runs and replay receipts from the dashboard
- ✓Wire up real Stripe / ACP rails when you're ready
Dataset Generation
Generate a certified synthetic dataset from a real template.
Create a synthetic dataset in-browser, download the CSV, and get a certificate proving when and how it was generated — with lineage back to the algorithm.
- →Generate across finance, healthcare, fraud, HR, and more — 1,000 rows per run by default
- →Download the CSV and the matching certificate immediately
- →10 generations per 24h anonymously — no account, no API key
- →Re-verify any dataset against the public signing key
- ✓Up to 10,000 rows per job · 5 jobs per month free
- ✓Save runs, rerun scenarios, keep a lineage history
- ✓Unlock downloads, certification, and template forking from the dashboard
For compliance and audit teams
Every demo produces evidence your auditor can verify — without access to our systems.
The full proof stack in under three minutes
Three pillars. One certification layer. All runnable without an account.
How the platform opens up
Start with the demos. Keep going when you're ready.
Run the real public demos anonymously. Inspect proof artifacts on the spot — Ed25519 signatures, SHA-256 hashes, machine-readable receipts.
Free account saves your runs, gives you an API key, and hands back audit-ready exports. No credit card, no commitment.
Start free — no credit cardPolicy controls, team workflows, retention, and EU AI Act-aligned compliance exports. All three pillars on one governed spine.

Every link is a live public endpoint — no account, no API key.
Public SDKs, receipts SDK, and utilities — all MIT-licensed.
Frequently asked
Do I need an account to try these demos?+
No. All three pillars — Decision Ledger, Agent Commerce, and Dataset Generation — run in-browser with generous anonymous limits. You get real Ed25519 signatures and real certificates whether or not you sign up.
Are the signatures real or simulated?+
Real. Every demo produces an Ed25519 signature over a canonicalized payload, a SHA-256 content hash, and a public verification URL. You can verify outside our system using our published public key.
What counts as an audit-ready export for EU AI Act purposes?+
Signed records include the decision or artifact, the hash, the signature, the signing key ID, and a canonical payload — the evidence chain an auditor needs for Article 12 (record-keeping) and Article 50 (transparency) obligations.
What are the anonymous limits?+
Decision Ledger: 30 signed demos per minute. Agent Commerce: 3 ephemeral sandbox keys per 24 hours with a 24h TTL. Dataset Generation: 10 generations per 24 hours at up to 1,000 rows each.
How does certification underpin all three pillars?+
Certification is the cryptographic layer. Decisions, agent-commerce receipts, and datasets are all certified artifacts — same Ed25519 signing, same SHA-256 hashing, same public verifiability. Three pillars, one proof system.
