Request API Access

API-first flow

  1. Authenticate via POST /p/uss/api/v1/oauth2/token using client credentials.
  2. Launch missions through POST /a/fes/api/v1/fraud-evaluations with actor traits and blockchain hints.
  3. Collect verdicts through webhooks or GET /a/fes/api/v1/fraud-evaluations/results?targets={targets} when offline.

Cache mission IDs and replay polling if downstream systems drop a webhook.

SDK capsules

Every SDK mirrors the HTTP schema and authentication.

Web

React SDK

Hooks for mission lifecycle plus status badges and optimistic flows.

Mobile

React Native SDK

Wallet permission bridges, biometric gating, and offline caching.

Cross-platform

Apple-native

Swift SDK

Combine-friendly APIs backed by Secure Enclave storage.

Choose the API for infrastructure-level control or jump into the SDKs for a UX-first rollout, both stay in lockstep via shared mission schemas.
