Documentation
Everything you need to integrate, understand, and extend SecureStamp.
Complete SSTP protocol endpoints: domain and email verification, trust scoring, stamp embed, webhooks, and more.
Authorize the effect, not just access to the tool: the canonical example, the three steps, the local authorization ceiling, the contracts the verifier recomputes, and how to verify a receipt offline.
The same layer at specification depth: the five-link proof chain, single-use grants, quorum profiles as signed policy snapshots, the open adapter platform and the evidence boundaries.
Technical specification and design rationale for the SecureStamp protocol: five-level trust model, notarial layer, Action Verdict, the Action Proof execution chain, signals, scoring and architecture.
How SecureStamp reaches L5 Certified: an ES256-signed notarial record of the message envelope plus business-identity (KYB) review. The five levels and the honest boundary: it certifies origin and integrity, not content truthfulness.
End-to-end encryption between verified identities is documented as a technical roadmap item. It is intentionally held back from the first .online onboarding and plugin release.
Guide to joining the SecureStamp federated network: requirements, setup, configuration, and node operator obligations.
Formal SSTP protocol specification on GitHub: messages, cryptography, validation, and federation rules.
Dictionary of SecureStamp, cryptography, email, protocol and infrastructure terms for end users, support teams and junior developers.
Quick start
The fastest way to verify a domain or email: a single GET request, no authentication required.
Try the verifiercurl -X POST https://securestamp.online/api/trust/check \
