Trust Stamp (T Stamp Inc., Nasdaq: IDAI) builds privacy-first identity technology: passive and active liveness with deepfake and injection-attack defence, document verification and KYC onboarding with sanctions, PEP and adverse media screening, built around irreversible IT² biometric tokens. Its products are priced through its sales team. Didit publishes its prices instead: passive liveness at $0.10, active at $0.15 and a full KYC at $0.33 a check, pay per use, with 500 free checks every month. Every check returns the score, the selfie, the capture video on active checks and every warning, and the same session carries into ID verification, database validation and AML screening, with the face reused for age estimation and 1:N face search, all on one user record.

Each Didit check returns the liveness score and method, the selfie, the capture video on active checks, face-quality metrics, matches against faces you have seen before and every warning that fired. Set your own review and decline thresholds.
Alongside liveness, ID verification, database validation and AML screening on one user record, Didit runs KYB and transaction monitoring on the same API. The same face powers age estimation, 1:N face search and duplicate and blocklist detection. Integrate by REST API, hosted link, iframe or SDK.
