This endpoint checks the cryptographic proof (e.g., signature) embedded within the badge to ensure it was genuinely issued by the claimed issuer (as identified in the proof's verificationMethod) and that its contents have not been altered since issuance. It may also perform checks on timeliness (validFrom/validUntil). This endpoint conforms to the verification principles outlined in the Open Badges v3.0 specification and W3C Verifiable Credentials Data Model. ## OpenAPI ````yaml /openapi/beyond-ai/openbadges-api.yaml post /ims/ob/v3p0/issue-badge/verify openapi: 3.1.0 info: title: OpenBadge API version: 1.0.0 description: >- Open Badges is a global standard for creating, issuing, and verifying digital micro-credentials that represent skills, achievements, learning outcomes, and experiences.
