pynukez 3.4.0

Nukez SDK — agent-native storage with cryptographic verification

PyNukez

Persistent storage for AI agents. Pay with SOL, store anything, get cryptographic proof.

pip install pynukez[solana]

30-Second Example

from pynukez import Nukez

client = Nukez(keypair_path="~/.config/solana/id.json")

# Buy storage
request = client.request_storage()
transfer = client.solana_transfer(request.pay_to_address, request.amount_sol)
receipt = client.confirm_storage(request.pay_req_id, transfer.signature)

# Use it
client.provision_locker(receipt.id)
urls = client.create_file(receipt.id, "notes.txt")
client.upload_bytes(urls.upload_url, b"Hello!")
data = client.download_bytes(urls.download_url)  # b"Hello!"

That's it. Your agent now has permanent storage with a cryptographic receipt.

First Time? Start Here

1. Get a Solana Wallet

# Install Solana CLI
sh -c "$(curl -sSfL https://release.solana.com/stable/install)"

# Create wallet
solana-keygen new --outfile ~/.config/solana/id.json

2. Get Test Money (Free)

solana config set --url devnet
solana airdrop 2

3. Install PyNukez

pip install pynukez[solana]

4. Store Something

from pynukez import Nukez

client = Nukez(keypair_path="~/.config/solana/id.json")

# Buy storage (costs ~0.001 SOL on devnet)
request = client.request_storage()
transfer = client.solana_transfer(request.pay_to_address, request.amount_sol)
receipt = client.confirm_storage(request.pay_req_id, transfer.signature)

print(f"Your receipt: {receipt.id}")  # Save this!

# Create your locker
client.provision_locker(receipt.id)

# Store a file
urls = client.create_file(receipt.id, "my_file.txt")
client.upload_bytes(urls.upload_url, b"My agent's data")

# Read it back
data = client.download_bytes(urls.download_url)
print(data)  # b"My agent's data"

Quick Reference

What you want	Code
Buy storage	request = client.request_storage()
Pay	transfer = client.solana_transfer(request.pay_to_address, request.amount_sol)
Get receipt	receipt = client.confirm_storage(request.pay_req_id, transfer.signature)
Setup locker	client.provision_locker(receipt.id)
Store data	urls = client.create_file(receipt.id, "file.txt") then client.upload_bytes(urls.upload_url, data)
Get data	data = client.download_bytes(urls.download_url)
List files	files = client.list_files(receipt.id)
Delete file	client.delete_file(receipt.id, "file.txt")
Verify	result = client.verify_storage(receipt.id)
Merkle proof	proof = client.get_merkle_proof(receipt.id, "file.txt")

Sandboxed App Uploads

If your agent runs in a proxied app sandbox (for example, /mnt/data path restrictions), path uploads can fail even when locker auth is valid.

Use the sandbox ingest flow instead:

job = client.sandbox_create_ingest_job(
    receipt_id=receipt.id,
    files=[{"filename": "image.png", "content_type": "image/png"}],
)

client.sandbox_append_ingest_part(
    receipt_id=receipt.id,
    job_id=job["job_id"],
    file_id=job["files"][0]["file_id"],
    part_no=0,
    payload_b64="<chunk-0-base64>",
    is_last=True,
)

result = client.sandbox_complete_ingest_job(
    receipt_id=receipt.id,
    job_id=job["job_id"],
)

Convenience helpers are available:

• client.sandbox_upload_bytes(...)
• client.sandbox_upload_base64(...)
• client.sandbox_upload_file_path(...)

Important: if a valid receipt_id already exists, reuse it. Do not purchase storage again unless explicitly requested.

---

Important

Save your receipt.id — you need it for everything.

# First time
receipt = client.confirm_storage(...)
print(receipt.id)  # Save this string somewhere!

# Later
files = client.list_files("your_saved_receipt_id")

---

Going to Production

Change one line:

# Devnet (testing)
client = Nukez(keypair_path="~/.config/solana/id.json", network="devnet")

# Mainnet (production)
client = Nukez(keypair_path="~/.config/solana/id.json", network="mainnet-beta")

---

Common Issues

Problem	Fix
"Transaction not found"	Wait 3 seconds and retry confirm_storage()
"Insufficient funds"	Run solana airdrop 2 (devnet only)
"URL expired"	Call client.get_file_urls(receipt_id, filename) for fresh URLs
"File not found"	Check client.list_files(receipt_id) to see what exists
