Welcome to Treeship

Treeship provides cryptographic attestations for AI agents. Every action your agent takes can be signed, timestamped, and independently verified by anyone.

​
Why Treeship?

When AI agents make decisions, users need to trust that the agent did what it claimed to do. Treeship solves this by:
  • Signing every action with Ed25519 cryptographic signatures
  • Timestamping attestations immutably
  • Enabling independent verification without trusting Treeship’s servers
  • Providing a public verification page for transparency

​
Quick Example

from treeship_sdk import Treeship

ts = Treeship(api_key="your-key")

# Create an attestation
result = ts.attest(
    agent="my-agent",
    action="Approved loan application #12345",
    inputs_hash=ts.hash(application_data)
)

# Share the verification URL
print(result.verify_url)  # https://treeship.dev/verify/my-agent/abc-123...
Anyone can verify this attestation: 
treeship verify abc-123-def-456
# ✓ Attestation verified
