# SmartBlocks Network Python SDK

Canonical Python client for the SBN infrastructure. Covers the full network
surface — gateway, SnapChore, console, and control plane.

## Install

```bash
pip install sbn-sdk
# or from source
cd sdk/python && pip install -e .
```

## Quick start

```python
from sbn import SbnClient

client = SbnClient(base_url="https://api.smartblocks.network")
client.authenticate_api_key("sbn_live_abc123")

# SnapChore — capture, verify, seal
block = client.snapchore.capture({"event": "signup", "user": "u-42"})
client.snapchore.verify(block["snapchore_hash"], {"event": "signup", "user": "u-42"})
client.snapchore.seal(block["snapchore_hash"], {"event": "signup", "user": "u-42"})

# Gateway — slots, receipts, attestations
slot = client.gateway.create_slot(worker_id="w-1", task_type="classify")
receipt = client.gateway.fetch_receipt(slot.receipt_id)

# Console — API keys, usage, billing
keys = client.console.list_api_keys("proj-123")
usage = client.console.get_usage("proj-123")

# Control plane — rate plans, tenants, validators
plans = client.control_plane.list_rate_plans()
client.control_plane.create_tenant(
    name="Acme Corp",
    contact_email="ops@acme.co",
    aggregator_endpoint="https://agg.acme.co",
    rate_plan_id=plans[0].id,
)
```

## Auth methods

```python
# API key (most common for external devs)
client.authenticate_api_key("sbn_live_...")

# Bearer token (console sessions, service-to-service)
client.authenticate_bearer("eyJ...")

# Ed25519 signing key (auto-refreshing JWTs for agents)
from sbn import SigningKey
key = SigningKey.from_pem("/path/to/key.pem", issuer="my-svc", audience="sbn")
client.authenticate_signing_key(key, scopes=["attest.write", "snapchore.seal"])
```

## Sub-clients

| Property | Domain | Key operations |
|----------|--------|----------------|
| `client.gateway` | Slots & receipts | `create_slot`, `close_slot`, `fetch_receipt`, `request_attestation` |
| `client.snapchore` | Hash capture | `capture`, `verify`, `seal`, `create_chain`, `append_to_chain` |
| `client.console` | Developer console | `list_api_keys`, `create_api_key`, `get_usage`, `get_billing_status` |
| `client.control_plane` | Multi-tenancy | `list_rate_plans`, `create_tenant`, `register_validator` |

## Legacy compatibility

The original `sbn_gateway.py` single-file SDK is preserved for backward
compatibility. New integrations should use `from sbn import SbnClient`.
