Build on PTI
Developers
Integrate Portable Trust Infrastructure the way institutions and partners actually run it: authenticate, resolve identity in directory, generate a context-aware trust lookup, then poll the report or receive a verified webhook. Sandbox keys live in your workspace under API & trust signals.
Open specification
PTI Specification v1.0
TumiTrust is the reference implementation. The specification defines the category — reference architecture, security model, and governance for compatible platforms.
Authenticate
Ping with sandbox or live API keys from your institution workspace.
Resolve
Directory search to find the right subject for the decision.
Generate
Request a context-scoped trust lookup / report for that purpose.
Deliver
Poll JSON or receive a verified webhook when the report is ready.
Trust platform API
Lookups, reports, authentication, and sandbox vs live keys.
Webhooks
Verified delivery when you prefer push over poll.
Partner connectors
Produce trust signals via webhook, API, or controlled ingest.
Trust contexts
Primaries and lenses — scope every signal to a real decision.
Screening services
Sanctions / PEP / list checks as an API product next to PTI.
Reference architecture
Logical layers for CTOs evaluating the category.
Build your own PTI
Implement a compatible platform from the open specification.
