Get started with Attesto

This guide gets a tenant from first login to a verified event without relying on generated content or temporary flows.

export OPENAI_BASE_URL=http://localhost:8765/v1

1. Sign in to the tenant dashboard

Use dashboard.attesto.eu. Tenant users manage their own systems, keys, Proofstream views, exports, billing, webhooks, and connectors there. New tenant signup asks the owner to choose Starter, Growth, or Realtime and then starts the configured 30-day Stripe trial through Checkout. Enterprise onboarding is handled with Attesto sales.

2. Register a system

Open Settings -> Systems, create a system for the production service that will send events, and copy the generated system key when it is shown. The key is displayed once and must be stored in your server-side secret manager.

3. Log the first event from server-side code

SDK defaults point at https://verify.attesto.eu. Do not embed Attesto system keys in browser bundles, mobile apps, client logs, or client-visible environment variables.

python - <<'PY'
import os
from datetime import UTC, datetime
from attesto import AttestoClient

attesto = AttestoClient(api_key=os.environ["ATTESTO_API_KEY"])
ack = attesto.log_event(
    type="inference",
    status="verified",
    ts=datetime.now(UTC),
    payload={"model": "risk-service-v4", "decision": "review"},
)
print(ack.id)
PY

4. Verify evidence

For v1 anchored events, retrieve the event proof and submit it to the public verifier. For v2 Proofstream, verify receipts, streams, checkpoints, and bundles through the SDK helper or the POST /v2/verify API.

5. Export for an auditor

In the dashboard, create an evidence export for the required date range. Attesto bundles include verifiable material and must be treated as immutable evidence files once shared.
