Digital Credentials API
ISO 18013-7:2025 Annex C DC API SDK
Part of the ONEPROOF Server SDK: one SDK that verifies every supported credential, mDL, EUDI PID, and other ISO mdoc credentials, with no per-credential add-ons. This SDK implements the W3C Digital Credentials API protocol for browser based digital identity credential presentation. Available individually or as part of the full ISO 18013-7 bundle.
Protocol Capabilities
DC API Browser-Side mDL Verification
The Digital Credentials API protocol enables web relying parties to request credentials from a user's digital wallet through the browser. mDL, EUDI PID, and other ISO mdoc credentials are supported. No native app required on the verifier side.
ISO 18013-7:2025 Annex C (Digital Credentials API)
W3C Digital Credentials API integration for browser based credential requests. Enables web relying parties to request ISO compliant digital identity data (mDL and other credential types) from the operating system credential layer.
Selective Disclosure
Request only the credential fields your use case requires: age, name, address, or any ISO defined element. No full credential transfer, no unnecessary PII exposure.
Browser Native Integration
Designed for web relying parties. The DC API protocol works within the browser credential request flow. No native app integration required on the verifier side.
Cryptographic Verification
All credential presentations are COSE signed and verified against the issuer certificate chain. Cryptographic assurance without biometrics or document uploads.
Interoperable
Works with any ISO 18013-7 compliant wallet, including Apple Wallet, Google Wallet, and DMV issued wallets that support the DC API presentation protocol.
Server Side SDK
ONEPROOF provides the server side verification engine. You deploy in your infrastructure. No hosted API, no ONEPROOF dependency in your production stack.
Use Cases
Where DC API Deploys
Browser Based KYC at Onboarding
