A SHA-256 fingerprint is computed over the canonical API description plus ruleset identity and profile, enabling anyone to detect drift or forgery. The tool has two modes: Issue (mint a certificate from a Spectral validation result) and Verify (check a certificate against an API description). Everything runs client-side with no server involved. Certificates can be referenced from apis.json so consumers can verify trust before writing integration code, turning governance from a private producer ritual into a publicly checkable signal. ## Full article daily.dev links to this article rather than hosting it.
