Independent Verification

Verify this attestation without trusting Treeship. Run these commands locally:

1. Download the public key (raw PEM):

curl -s https://api.treeship.dev/v1/pubkey.pem -o pubkey.pem

2. Save the canonical payload (no trailing newline):

printf '%s' '{"action":"Verification test - all systems operational","agent_slug":"treeship-dev-agent","attestation_id":"9c3220e8-4d47-49cb-81d1-768fe8914cbb","inputs_hash":"test123","timestamp":"2026-02-23T23:46:01.811Z"}' > payload.txt

3. Verify the signature (requires: pip install cryptography):

python3 -c "from cryptography.hazmat.primitives.serialization import load_pem_public_key;import base64;pub = load_pem_public_key(open('pubkey.pem','rb').read());sig = base64.b64decode('kRq7Cz7qWGOhEZwXnx+0byMe0ANnx9De2458A2kkORpqvb1yFuMv536cuRPszL+eoVMkSTfsITf0ZVijcwcQBg==');payload = open('payload.txt','rb').read();pub.verify(sig, payload);print('VERIFIED: Signature is valid')"

If the signature is valid, you'll see VERIFIED: Signature is valid. If tampered with, Python will raise an InvalidSignature error. This proves the attestation is authentic — no Treeship API needed.
