[![PyPI version](https://img.shields.io/pypi/v/cerebe)](https://pypi.org/project/cerebe/)
[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](https://opensource.org/licenses/MIT)

Python SDK for the [Cerebe](https://cerebe.ai) Cognitive Services Platform — memory, knowledge graphs, meta-learning, and agent tooling.

## Installation

```bash
pip install cerebe
```

## Quick Start

```python
from cerebe import Cerebe

client = Cerebe(api_key="ck_live_xxx", project="proj_xxx")

# Store a memory
client.memory.add(
    "User prefers dark mode",
    "sess_123",
    type="semantic",
    importance=0.8,
)

# Search memories
results = client.memory.search("user preferences", "sess_123")
print(results.data)
```

### Async

```python
from cerebe import AsyncCerebe

async with AsyncCerebe(api_key="ck_live_xxx") as client:
    results = await client.memory.search("user preferences", "sess_123")
```

Every method available on `Cerebe` has an identical async counterpart on `AsyncCerebe`.

## Configuration

| `max_retries` | `int` | `3` | Max retries on 429/5xx |

Environment variable fallbacks: `CEREBE_API_KEY`, `CEREBE_PROJECT`, `CEREBE_BASE_URL`.

    "math concepts",
    "sess_123",

```python
client.knowledge.ingest(
    "Photosynthesis converts light energy to chemical energy",
    entity_id="biology_101",
    source="textbook",
)

graph = client.knowledge.query("photosynthesis", depth=3)
```

### Storage — `client.storage`

| Method | Description |
| ------ | ----------- |
| `upload(content, filename, content_type)` | Upload file (base64) |
| `presigned_upload(file_name, file_type, ...)` | Get presigned upload URL |
| `get(upload_id)` | Get file metadata |
| `get_url(upload_id)` | Get ephemeral download URL |
| `file_url(file_id)` | Get download URL by file ID |
| `check_hash(content_hash)` | Deduplication check |
| `analyze_content(upload_id, ...)` | Analyze file content |
| `extract(url, ...)` | Extract content from URL |

```python
# Get presigned upload URL
result = client.storage.presigned_upload(
    file_name="essay.pdf",
    file_type="application/pdf",
    file_size=102400,
    content_hash="sha256_abc123",
    tenant_id="tenant_1",
)

# Analyze uploaded content

```

### Meta-Learning — `client.meta_learning`

| Method | Description |
| ------ | ----------- |
| `analyze(user_id, ...)` | Analyze learning patterns |
| `profile(user_id)` | Get learner profile |

## Error Handling

```python
from cerebe import Cerebe
from cerebe._errors import (
    AuthenticationError,
    NotFoundError,
    RateLimitError,
    ValidationError,
    ServerError,
)

client = Cerebe(api_key="ck_live_xxx")

try:
    client.memory.get("mem_nonexistent")
except NotFoundError:
    print("Memory not found")
except RateLimitError as e:
    print(f"Rate limited, retry after {e.retry_after}s")
except AuthenticationError:
    print("Invalid API key")
```

| Error Class | HTTP Status | Description |
| ----------- | ----------- | ----------- |
| `AuthenticationError` | 401 | Invalid or missing API key |
| `NotFoundError` | 404 | Resource not found |
| `ValidationError` | 400, 422 | Invalid request parameters |
| `RateLimitError` | 429 | Rate limit exceeded |
| `ServerError` | 5xx | Server-side error |

## Retries

The SDK automatically retries on:

- **429** (Rate Limited) — respects `Retry-After` header
- **5xx** (Server Error) — exponential backoff

Set `max_retries=0` to disable.

## Type Safety

The SDK is fully typed with `py.typed` marker (PEP 561).
Works with mypy, pyright, and IDE autocomplete.

```python
from cerebe.resources.memory import MemoryType

memory_type: MemoryType = "semantic"  # type-checked literal
```

## Requirements

- Python >= 3.10
- httpx >= 0.25.0
- pydantic >= 2.0.0
