Pricing
Early pricing — effective 14 July 2026. All prices in USD, exclusive of taxes. Fiat via Stripe (subscriptions) or USDC via x402 (machine-payable, identical entitlements). Every tier includes the data-escape guarantee: scheduled exports to storage you own, a 90-day post-termination export window, and on-chain-anchored digests that stay third-party-verifiable forever.

Evidence pack formats: art50 (EU AI Act Article 50 disclosure evidence) · art226b (EU simplified-invoice content — CI-validated) · s51c (HK IRO records retention — CI-validated) · safr (MAS SAFR alignment mapping — beta). Export formats other than art226b/s51c are mappings, not compliance certifications — see Terms §18.
Free tier is for digests and business data only (no personal data). Prices may change with 30 days' notice per the Terms; the tier you're on is honored through your current billing period.
