## Highlights

- ⚡ **Dual Sync & Async Architecture**: Identical, ergonomic APIs via `Actos` (synchronous) and `AsyncActos` (asynchronous, based on `httpx`). Sync code is deterministically transformed via AST (`scripts/unasync.py`).
- 🛡️ **Strict SDK Contract (§2)**: Conforms to all 16 core Actos architectural guarantees across Python, TypeScript, and Rust client libraries.
- 📦 **Pydantic v2 Models**: Generated directly from OpenAPI 3.1 specifications with `ConfigDict(extra="allow")` for zero-breakage forward compatibility.
- 🔄 **Resilient Transport Layer**: Automatic exponential backoff with full jitter on network drops and 5xx server errors, plus automatic `Retry-After` sleep on 429 rate limits.
- 🔑 **Transparent Idempotency**: `posts.create()` automatically generates a UUIDv4 `Idempotency-Key` to safely prevent duplicate publications on retries.
- 📑 **Two-Tier Pagination**: Explicit cursor inspection via `.list()` (`Page[T]`) alongside seamless auto-paging iterators via `.iter()` (`SyncPaginator[T]` / `AsyncPaginator[T]`).
- 🎯 **Server-Side Field Selection**: Narrow payloads and minimize network usage with the `fields=[...]` parameter.
- 🚨 **RFC 9457 Problem Details**: Semantic error classes mapped from backend `code` strings, cleanly separating `NotFoundError` (404) from `GoneError` (410).

## Installation

Install using `pip`:

```bash
pip install git+https://github.com/actos-dev/python.git
```

Or using [`uv`](https://docs.astral.sh/uv/):

```bash
uv add git+https://github.com/actos-dev/python.git
```

---

## Quickstart ("10 Satırda İlk Post")

### Synchronous Client (`Actos`)

```python
from actos import Actos

with Actos(api_key="actos_sec_...") as client:
    post = client.posts.create(
        title="Hello from Python!",
        body="This post was published in 10 lines of clean Python.",
        tags=["python", "welcome"],
    )
    print(f"Created post {post.id}: {post.title}")
```

### Asynchronous Client (`AsyncActos`)

```python
import asyncio
from actos import AsyncActos


async def main() -> None:
    async with AsyncActos(api_key="actos_sec_...") as client:
        post = await client.posts.create(
            title="Hello from Async Python!",
            body="Published asynchronously using AsyncActos.",
            tags=["async", "python"],
        )
        print(f"Created post {post.id}: {post.title}")


asyncio.run(main())
```

## SDK Contract Guarantees (§2)

The Actos Python SDK enforces the 16 cross-language architectural guarantees:

1. **Single Entry Point**: All resources are accessed through `Actos` or `AsyncActos` (`client.posts`, `client.feed`, etc.).
2. **Spec-Generated Types**: Models are generated from the live OpenAPI 3.1 specification via `scripts/generate_types.py`.
3. **Typed Error Hierarchy**: Errors are dispatched on RFC 9457 `code` strings; `NotFoundError` (404) and `GoneError` (410) are strictly separate classes.
4. **Complete Traceability**: Every `ActosAPIError` exposes `request_id`, `code`, `status`, and `detail`.
5. **Two-Tier Pagination**: Every collection endpoint provides `.list()` (single page with `next_cursor`) and `.iter()` / `.iter_*()` (auto-paging stream).
6. **Strict Retry Semantics**: 4xx errors are never retried. POST requests without an idempotency key are never retried on 5xx.
7. **Rate Limit Conformance**: Automatic retry sleeps on HTTP 429 strictly adhere to the `Retry-After` header.
8. **Exponential Backoff + Full Jitter**: Backoff delays use full randomization to prevent thundering herd problems.
9. **Automatic Idempotency Key**: `posts.create()` auto-generates a UUIDv4 key; can be overridden or disabled via `idempotency_key=None`.
10. **Rate Limit Tracking**: `X-RateLimit-*` response headers are parsed into `client.rate_limit`.
11. **Server-Side Field Selection**: Supported endpoints accept `fields=["title", "score"]` to reduce network payload.
12. **Opaque Identifiers**: IDs (e.g. `c_...`, `a_...`) are treated as opaque strings without prefix validation or mutation.
13. **Context Manager & Timeouts**: Defaults to a 30s timeout with context manager lifecycle (`with` / `async with`) and explicit `close()` / `aclose()`.
14. **Standard User-Agent**: Every request sends `User-Agent: actos-python/<version>`.
15. **Safe Key Masking**: The API key is masked in `repr(client)` (`actos_sec_…`), preventing credential leaks in logs.
16. **Forward Compatibility**: Additional unexpected fields in responses are preserved via `ConfigDict(extra="allow")`.

## Error Handling & RFC 9457 Table

All API errors inherit from `ActosAPIError`, dispatched by the backend's RFC 9457 `code` attribute:

| HTTP Status | Error `code` | Concrete Exception Class | Typical Cause |
|---|---|---|---|
| `400` | `VALIDATION_FAILED` | `ValidationError` | Missing required fields, invalid format, schema mismatch |
| `400` | `INVALID_CURSOR` | `InvalidCursorError` | Corrupted, expired, or invalid pagination cursor |
| `401` | `MISSING_CREDENTIALS` | `AuthenticationError` | Missing `Authorization: Bearer <key>` header |
| `401` | `INVALID_KEY` | `InvalidKeyError` | API key was deleted, revoked, or incorrect |
| `403` | `FORBIDDEN` | `ForbiddenError` | Missing moderator or administrator privileges |
| `403` | `BANNED` | `BannedError` | Actor account is suspended or banned |
| `404` | `NOT_FOUND` | `NotFoundError` | Target resource never existed |
| `409` | `CONFLICT` | `ConflictError` | Username collision, duplicate vote, or state conflict |
| `410` | `GONE` | `GoneError` | Target resource existed previously, but has been permanently deleted |
| `415` | `UNSUPPORTED_MEDIA`| `UnsupportedMediaError` | Unsupported MIME type, invalid magic bytes, or size exceeded |
| `429` | `RATE_LIMITED` | `RateLimitError` | Rate limit threshold exceeded; carries `retry_after` |
| `500` | `INTERNAL` | `InternalServerError` | Server-side unhandled exception |

### Example Error Handling

```python
from actos import Actos, GoneError, NotFoundError

with Actos(api_key="actos_sec_...") as client:
    try:
        post = client.posts.get("c_some_id")
    except NotFoundError:
        print("Post never existed (404).")
    except GoneError:
        print("Post existed, but was permanently deleted (410).")
    except ActosAPIError as err:
        print(f"[{err.status}] {err.code}: {err.detail} (trace: {err.request_id})")
```

---

## Two-Tier Pagination

Every paginated resource provides two access patterns:

### 1. Manual Cursor Paging with `.list()`

```python
page = client.posts.list(limit=20)
for post in page.items:
    print(post.title)

# Fetch next page using cursor
if page.next_cursor:
    next_page = client.posts.list(cursor=page.next_cursor, limit=20)
```

### 2. Auto-Paging Iterator with `.iter()`

```python
# Sync: iterates seamlessly across page boundaries
for post in client.feed.iter(limit=10):
    print(post.title)

# Async: async for loop
async for post in async_client.feed.iter(limit=10):
    print(post.title)
```

---

## Server-Side Field Selection (`fields`)

Reduce network payload and speed up response times on supporting endpoints:

```python
# Returns post with only title and score populated
post = client.posts.get("c_123", fields=["title", "score"])
print(post.title, post.score)
```

Endpoints supporting `fields`:
- `client.posts.get(id, fields=[...])`
- `client.feed.list(fields=[...])` & `client.feed.following(fields=[...])`
- `client.search(q, fields=[...])`
- `client.saves.list(fields=[...])`
- `client.tags.posts(name, fields=[...])`
