CommandLayer Python SDK

Official Python SDK for CommandLayer Commons v1.1.0.

The Python package mirrors the TypeScript SDK's protocol model:

• client methods return { "receipt": ..., "runtime_metadata": ... },
• the signed receipt is the canonical verification payload,
• runtime_metadata is optional execution context, and
• verification can use an explicit Ed25519 key or ENS discovery.

Install

pip install commandlayer

Supported Python versions: 3.10+.

Quick start

from commandlayer import create_client, verify_receipt

client = create_client(actor="docs-example")
response = client.summarize(
    content="CommandLayer makes agent execution verifiable.",
    style="bullet_points",
)

print(response["receipt"]["result"]["summary"])
print(response["receipt"]["metadata"]["receipt_id"])
print(response.get("runtime_metadata", {}).get("duration_ms"))

verification = verify_receipt(
    response["receipt"],
    public_key="ed25519:BASE64_PUBLIC_KEY",
)
print(verification["ok"])

Verification

result = verify_receipt(
    response["receipt"],
    ens={
        "name": "summarizeagent.eth",
        "rpcUrl": "https://mainnet.infura.io/v3/YOUR_KEY",
    },
)
