API Capabilities

Identity Activation

POST /v1/did/activate

One POST creates a verified identity, generates an API key, and returns a digital fingerprint. No wallet setup, no key management.

Sealed Envelope Delivery

POST /v1/channel/send

Send end-to-end encrypted messages between identities. Metadata is stripped and sealed before routing — immutably.

Identity Status & Usage

POST /v1/did/status

Query real-time usage metrics, plan limits, and identity status for any API key in your account.

Webhook Management

POST /v1/webhooks/register

Trust & Compliance

Key Isolation

All signing keys are generated, encrypted, and stored by Arcform. No client-side key access.

Strip & Seal

Immutable metadata stripping on every envelope. No toggle, no opt-out. Privacy by architecture.

Sovereign Proxy

Arcform is the cryptographic actor of record. Developers never sign, encrypt, or resolve DIDs.

Use Cases

Secure inter-service communication

Privacy-preserving messaging applications

Compliance-grade audit trails

IoT device identity and messaging

Healthcare data exchange (HIPAA-aligned)

Financial services secure channels
