onyx_attestation_verify

Active

declared in 1.26.0

Verify an Onyx-signed security verdict. Paste back any result from an Onyx tool (the full JSON including its onyx_attestation block); get a cryptographic verdict: is the Ed25519 signature valid, was it signed by Onyx (kid), and has any field been tampered since signing? FREE. Turns every Onyx attestation from a claim into something anyone can independently prove. Cross-check the kid against /.well-known/onyx-pubkey. (price: $0 USDC, tier: free)
