AI Decision Evidence

Issue and verify in
a few lines

Evidence is produced inline with the decision — no separate logging step to forget. Verification is a stock-crypto operation you can run anywhere: Python, TypeScript, or the open-source eve-verify CLI.

Every decision returns a signed record

Python · TypeScript · CLI

The open-source eve-verify package ships all three. Same canonicalization, same result.

verify — TypeScriptnpm i eve-verify
import { verifyCertificate } from "eve-verify";

const ok = await verifyCertificate(cert, PUBLIC_KEY_HEX);
console.log(ok ? "✓ authentic" : "✗ tampered");
verify — CLIzero EVE dependency
pip install eve-verify
eve-verify certificate.json
# → ✓ gdc_8f31a0c4e9b7: authentic and intact

# Tamper one byte and re-run → ✗ FAIL

FAQ

Common questions

Is the verifier open source?
Yes — eve-verify ships Python, TypeScript, and a CLI under a permissive license, with sample certificates and a versioned verification specification.
What does the decision API return?
A response with the decision status, a risk assessment, and a signed audit record. The signature is over the canonical payload and is independently verifiable.
Where is the full API reference?
On the EVE AI Core docs at eveaicore.com/docs — EVE Proof links to it rather than duplicating platform documentation.
