# Alter SDK for Python

Official Python SDK for [Alter Vault](https://alterai.dev) - Credential management for agents with policy enforcement.

## Features

- **Zero Token Exposure**: Tokens are never exposed to developers - injected automatically
- **Single Entry Point**: One method (`vault.request()`) for all provider APIs
- **Type-Safe Enums**: `Provider` and `HttpMethod` enums with autocomplete
- **URL Templating**: Path parameter substitution with automatic URL encoding
- **Automatic Audit Logging**: All API calls logged with request metadata (HTTP method and URL) for full audit trail
- **Real-time Policy Enforcement**: Every token request checked against current policies
- **Automatic Token Refresh**: Tokens refreshed transparently by the backend
- **API Key and Custom Credential Support**: Handles OAuth tokens, API keys, and custom credential formats automatically
- **HMAC Request Signing**: All SDK-to-backend requests are cryptographically signed for integrity, authenticity, and replay protection
- **Actor Tracking**: First-class support for AI agent and MCP server observability

## Installation

```bash
pip install alter-sdk
```

## Quick Start

```python
import asyncio
from alter_sdk import AlterVault, ActorType, Provider, HttpMethod

async def main():
    vault = AlterVault(
        api_key="alter_key_...",
        actor_type=ActorType.AI_AGENT,
        actor_identifier="my-agent",
    )

    # Make API request -token injected automatically, never exposed
    response = await vault.request(
        "CONNECTION_ID",  # from Alter Connect (see below)
        HttpMethod.GET,
        "https://api.example.com/v1/resource",
        query_params={"maxResults": "10"},
    )
    events = response.json()
    print(events)

    await vault.close()

asyncio.run(main())
```

### Where does `connection_id` come from?

**OAuth connections** (per-user, from end user action):
1. Your **end user** completes OAuth via [Alter Connect](https://docs.alterai.dev/sdks/javascript/quickstart) (frontend widget) or `vault.connect()` (headless)
2. The `onSuccess` callback returns a `connection_id` (UUID) -one per user per account
3. You save it in your database, mapped to your user
4. You pass it to `vault.request()` when making API calls

**Managed secrets** (per-service, from developer action):
1. **You** store credentials in the [Developer Portal](https://portal.alterai.dev) under **Managed Secrets**
2. The portal returns a `connection_id` -one per stored credential, shared across your backend
3. Use the same `vault.request()` -credentials are injected automatically

```python
# You can also discover connection_ids programmatically:
result = await vault.list_connections(provider_id="google")
for conn in result.connections:
    print(f"{conn.connection_id}: {conn.account_display_name}")
```

## Usage

The `request()` method returns the raw `httpx.Response`. The token is injected automatically and never exposed.

### Simple GET Request

```python
response = await vault.request(
    connection_id,
    HttpMethod.GET,
    "https://api.example.com/v1/resource",
)
```

### POST with JSON Body

```python
response = await vault.request(
    connection_id,
    HttpMethod.POST,
    "https://api.example.com/v1/items",
    json={"name": "New Item", "price": 99.99},
    reason="Creating new item",
)
```

### URL Path Templating

```python
response = await vault.request(
    connection_id,
    HttpMethod.PUT,
    "https://api.example.com/v1/items/{item_id}",
    path_params={"item_id": "123"},
    json={"price": 89.99},
)
```

### Query Parameters and Extra Headers

```python
response = await vault.request(
    connection_id,
    HttpMethod.POST,
    "https://api.notion.com/v1/databases/{db_id}/query",
    path_params={"db_id": "abc123"},
    extra_headers={"Notion-Version": "2022-06-28"},
    json={"page_size": 10},
)
```

### Context Manager

```python
async with AlterVault(
    api_key="alter_key_...",
    actor_type=ActorType.BACKEND_SERVICE,
    actor_identifier="my-service",
) as vault:
    response = await vault.request(
        connection_id,
        HttpMethod.GET,
        "https://api.example.com/v1/resource",
    )
# Automatically closed
```

> **Note:** After `close()` is called, subsequent `request()` calls raise `AlterSDKError`. `close()` is idempotent -calling it multiple times is safe.

### Using Managed Secrets

For your own APIs with API keys or service tokens (no OAuth flow needed):

```python
async with AlterVault(
    api_key="alter_key_...",
    actor_type=ActorType.BACKEND_SERVICE,
    actor_identifier="my-service",
) as vault:
    response = await vault.request(
        "MANAGED_SECRET_CONNECTION_ID",  # from Developer Portal
        HttpMethod.GET,
        "https://api.internal.com/v1/data",
    )
```

The credential is injected automatically as the configured header type (Bearer, API Key, Basic Auth).

### Connection Management

#### List Connections

Retrieve OAuth connections for your app, optionally filtered by provider:

```python
from alter_sdk import AlterVault, ActorType

async with AlterVault(
    api_key="alter_key_...",
    actor_type=ActorType.BACKEND_SERVICE,
    actor_identifier="my-service",
) as vault:
    # List all connections
    result = await vault.list_connections()
    for conn in result.connections:
        print(f"{conn.provider_id}: {conn.account_display_name} ({conn.status})")

    # Filter by provider with pagination
    result = await vault.list_connections(provider_id="google", limit=10, offset=0)
    print(f"Total: {result.total}, Has more: {result.has_more}")
```

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `provider_id` | `str \| None` | `None` | Filter by provider (e.g., `"google"`) |
| `limit` | `int` | `100` | Max connections to return |
| `offset` | `int` | `0` | Pagination offset |

Returns `ConnectionListResult` with: `connections` (`list[ConnectionInfo]`), `total`, `limit`, `offset`, `has_more`.

#### Create Connect Session

Generate a session URL for end-users to authenticate with OAuth providers:

```python
session = await vault.create_connect_session(
    allowed_providers=["google", "github"],
    return_url="https://myapp.com/callback",
)
print(f"Connect URL: {session.connect_url}")
print(f"Expires in: {session.expires_in}s")
```

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `allowed_providers` | `list[str] \| None` | `None` | Restrict to specific providers |
| `return_url` | `str \| None` | `None` | Redirect URL after OAuth flow |

Returns `ConnectSession` with: `session_token`, `connect_url`, `expires_in`, `expires_at`.

#### Headless Connect (from code)

For CLI tools, Jupyter notebooks, and backend scripts -opens the browser, waits for the user to complete OAuth, and returns the result:

```python
results = await vault.connect(
    providers=["google"],
    connection_policy={  # optional TTL bounds
        "max_ttl_seconds": 86400,
        "default_ttl_seconds": 3600,
    },
    timeout=300,         # max wait in seconds (default: 5 min)
    open_browser=True,   # set False to print URL instead
)
for result in results:
    print(f"Connected: {result.connection_id} ({result.provider_id})")
    print(f"Account: {result.account_identifier}")

# Now use the connection_id with vault.request()
response = await vault.request(
    results[0].connection_id,
    HttpMethod.GET,
    "https://api.example.com/v1/resource",
)
```

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `providers` | `list[str] \| None` | `None` | Restrict to specific providers |
| `timeout` | `int` | `300` | Max seconds to wait for completion |
| `poll_interval` | `float` | `2.0` | Seconds between status checks |
| `connection_policy` | `dict \| None` | `None` | TTL bounds (`max_ttl_seconds`, `default_ttl_seconds`) |
| `open_browser` | `bool` | `True` | Open browser automatically |

Returns `list[ConnectResult]` -one per connected provider. Each has: `connection_id`, `provider_id`, `account_identifier`, `scopes`, and optionally `connection_policy` (if a TTL was set).

Raises `ConnectTimeoutError` if the user doesn't complete in time, `ConnectDeniedError` if the user denies authorization, `ConnectConfigError` if the OAuth app is misconfigured.

### AI Agent Actor Tracking

```python
from alter_sdk import AlterVault, ActorType, Provider, HttpMethod

vault = AlterVault(
    api_key="alter_key_...",
    actor_type=ActorType.AI_AGENT,
    actor_identifier="email-assistant-v2",
    actor_name="Email Assistant",
    actor_version="2.0.0",
    framework="langgraph",
)

response = await vault.request(
    connection_id,
    HttpMethod.GET,
    "https://api.example.com/v1/resource",
    run_id="550e8400-e29b-41d4-a716-446655440000",  # auto-generated UUID if omitted
    thread_id="thread-xyz",
    tool_call_id="call_abc_123",
)
```

> **Note**: `run_id` is auto-generated as a UUID v4 if not provided. All sub-actions within a single `request()` call share the same `run_id` for audit log grouping.

### Multi-Agent Deployments

Each agent must create its own `AlterVault` instance with a unique actor identity. Do not share a single instance across agents.

```python
# Each agent gets its own vault instance
email_agent = AlterVault(
    api_key="alter_key_...",
    actor_type=ActorType.AI_AGENT,
    actor_identifier="email-assistant-v2",
    actor_name="Email Assistant",
)

calendar_agent = AlterVault(
    api_key="alter_key_...",
    actor_type=ActorType.AI_AGENT,
    actor_identifier="calendar-agent-v1",
    actor_name="Calendar Agent",
)

# Audit logs and policies are tracked per agent
await email_agent.request(
    gmail_connection_id,  # from Alter Connect
    HttpMethod.GET,
    "https://api.example.com/v1/messages",
)
await calendar_agent.request(
    calendar_connection_id,  # from Alter Connect
    HttpMethod.GET,
    "https://api.example.com/v1/resource",
)

# Clean up each instance
await email_agent.close()
await calendar_agent.close()
```

## Configuration

```python
from alter_sdk import AlterVault, ActorType

vault = AlterVault(
    api_key="alter_key_...",              # Required: Alter Vault API key
    actor_type=ActorType.AI_AGENT,        # Required: ActorType enum
    actor_identifier="my-agent",          # Required: Unique identifier
    timeout=30.0,                         # Optional: HTTP timeout in seconds
    actor_name="My Agent",               # Optional: Human-readable name
    actor_version="1.0.0",               # Optional: Version string
    framework="langgraph",               # Optional: AI framework
    client_type="cursor",                # Optional: MCP client type
)
```

## Error Handling

The SDK provides a typed exception hierarchy so you can handle each failure mode precisely:

```
AlterSDKError (base)
├── BackendError                     # Generic backend error
│   ├── ReAuthRequiredError          # User must re-authorize via Alter Connect
│   │   ├── ConnectionExpiredError   # 403 — connection TTL elapsed
│   │   ├── ConnectionRevokedError   # 400 — auth permanently broken (revoked, invalid_grant)
│   │   └── ConnectionDeletedError   # 410 — user disconnected via Wallet (new ID on re-auth)
│   ├── ConnectionNotFoundError      # 404 — wrong connection_id

├── ProviderAPIError                 # Provider returned 4xx/5xx
│   └── ScopeReauthRequiredError    # 403 + scope mismatch — user must re-authorize
└── NetworkError                     # Backend or provider unreachable
    └── TimeoutError                 # Request timed out (safe to retry)
```

```python
from alter_sdk import AlterVault, Provider, HttpMethod
from alter_sdk.exceptions import (
    AlterSDKError,              # Base exception (including validation errors)
    BackendError,               # Generic backend error
    ReAuthRequiredError,        # Parent for all re-auth errors
    ConnectionDeletedError,     # User disconnected via Wallet — new ID on re-auth (410)
    ConnectionExpiredError,     # TTL expired — user must re-authorize (403)
    ConnectionNotFoundError,    # Wrong connection_id — check for typos (404)
    ConnectionRevokedError,     # Auth permanently broken — revoked/invalid_grant (400)
    PolicyViolationError,       # Policy denied access — business hours, IP, etc. (403)
    ConnectFlowError,           # Headless connect() failed (denied, provider error)
    ConnectDeniedError,         # User denied authorization
    ConnectConfigError,         # OAuth app misconfigured
    ConnectTimeoutError,        # Headless connect() timed out
    NetworkError,               # Backend or provider unreachable
    TimeoutError,               # Request timed out (subclass of NetworkError)
    ProviderAPIError,           # Provider API returned error (4xx/5xx)
    ScopeReauthRequiredError,   # 403 + scope mismatch (subclass of ProviderAPIError)
)

try:
    response = await vault.request(
        connection_id,
        HttpMethod.GET,
        "https://api.example.com/v1/resource",
    )

# --- Connection unusable — user must re-authorize via Alter Connect ---
except ConnectionExpiredError:
    # TTL set during Connect flow has elapsed
    print("Connection expired — prompt user to re-authorize")
except ConnectionRevokedError:
    # Auth permanently broken — user revoked at provider, refresh token
    # expired, or token refresh permanently failed (invalid_grant)
    print("Connection revoked — prompt user to re-authorize")
except ConnectionDeletedError:
    # User disconnected via Wallet — re-auth generates a NEW connection_id
    print("Connection deleted — prompt user to re-connect, store the new ID")
except ConnectionNotFoundError:
    # No connection with this ID exists — check for typos or stale references
    print("Connection not found — verify your connection_id")

# --- Policy restrictions — may resolve on its own ---
except PolicyViolationError as e:
    # Business hours, IP allowlist, or other policy denial
    print(f"Policy denied: {e.message} (reason: {e.policy_error})")
    print("Check policy config in Developer Portal, or queue work for later")

# --- Transient / infrastructure errors — safe to retry ---
except NetworkError as e:
    # TimeoutError is a subclass, so this catches both
    print(f"Network issue — retry with backoff: {e.message}")

except ScopeReauthRequiredError as e:
    print(f"Scope mismatch on {e.connection_id} - user needs to re-authorize")
    # Create a new Connect session so the user can grant updated scopes

# --- Provider errors ---
except ProviderAPIError as e:
    print(f"Provider error {e.status_code}: {e.response_body}")
```

### Re-authorization and Connection IDs

When a user re-authorizes through Alter Connect, the **same `connection_id` is preserved** in most cases. The existing connection record is updated in place with fresh tokens. You do **not** need to update your stored `connection_id`.

The exception is `ConnectionDeletedError` — the user disconnected via the Wallet, so re-authorization creates a new connection with a **new `connection_id`**. Store the new ID from the `ConnectResult`.

| Exception | Same `connection_id` after re-auth? |
|---|---|
| `ConnectionExpiredError` | Yes |
| `ConnectionRevokedError` | Yes |
| `ConnectionDeletedError` | **No** — new ID generated |
| `ConnectionNotFoundError` | N/A — ID never existed |

## Supported Providers

The SDK includes type-safe `Provider` enums for all 66 supported providers. Use them for filtering connections or as documentation -- `request()` takes a `connection_id` string, not a provider enum.

```python
from alter_sdk import Provider

# Custom providers (full OAuth implementations)
Provider.GOOGLE       # "google"
Provider.GITHUB       # "github"
Provider.SLACK        # "slack"
Provider.CALENDLY     # "calendly"
Provider.CLICKUP      # "clickup"
Provider.CANVA        # "canva"
# ... and 23 more (see Provider enum for full list)

# Config-driven providers (45 total) -- examples:
Provider.HUBSPOT      # "hubspot"
Provider.SALESFORCE   # "salesforce"
Provider.STRIPE       # "stripe"
Provider.MICROSOFT    # "microsoft"
Provider.DISCORD      # "discord"
Provider.SPOTIFY      # "spotify"
Provider.LINKEDIN     # "linkedin"
Provider.DROPBOX      # "dropbox"
Provider.FIGMA        # "figma"
# ... and 36 more (see Provider enum for full list)

# Usage: filter connections by provider
result = await vault.list_connections(provider_id=Provider.HUBSPOT)

# Usage: make requests with connection_id
await vault.request(connection_id, HttpMethod.GET, url)
```
