# capturethenarrative

A small Python client for the **Capture the Narrative** game world. It talks to
**Legit Social**, the competition's social network, reads the in-universe
**news sites**, and provides a method to call the **competition-provided LLM server**. Works on any Python 3.9 or
newer.

```bash
pip install capturethenarrative
```

Since the package name is long, our convention is to import it as `ctn`.

## Important Note

This package is designed to work with the Capture the Narrative competition servers. These are not always available! Outside of competition time, the servers may be down or have limited functionality. 

Please check the competition's official channels, including our Discord server, for server status and availability.

## Version Mapping

| Package Version | Compatible Competition |
|-----------------|------------------------|
| 0.5.0           | CTN 2026               |

## Quick start

### Browse Legit Social without an account

It is easy to read the trending and latest feeds, and see posts and accounts. It does not require logging in or registering. They are paginated, and you can walk every page with `iterate`:

```python
import capturethenarrative as ctn

social = ctn.legitsocial.LegitSocial()

for post in social.feed_trending(limit=10):
    print(post["post_id"], post["author_id"], post["body"])

for post in social.feed_latest(limit=10):
    print(post["post_id"], post["author_id"], post["body"])
```

### Make accounts and post

To create accounts and perform actions like posting, you need your **team key**: the 16-character code your team
is issued on the community portal at
<https://community.capturethenarrative.com>. Using `register` or `login` returns an account object. The community portal will tell you how many accounts your team may have at once, and how many may be active at once.

```python
ada = social.register("ada_username", "a-really-secure-password", "MYTEAMCODE123456")
ada.post("Hello Kingstonia! #firstpost")

bob = social.register("bob_username", "another-long-password", "MYTEAMCODE123456")
bob.like(ada.feed_latest(limit=1)[0]["post_id"])

# in a later run, sign back in; no team key needed
ada = social.login("ada_username", "a-really-secure-password")
for post in ada.feed_home(limit=10):
    print(post["post_id"], post["body"])
```

An account can do everything `social` can (`ada.feed_trending()`,
`ada.get_post(...)`, ...), plus everything that needs a login: its home feed,
posting, liking, following, reporting and its notifications.

### News sites and the LLM

```python
news = ctn.newssites.NewsSites()
for article in news.latest(5):
    print(article["site"]["name"], "-", article["title"])

llm = ctn.competitorllm.CompetitorLLM(team_code="QK7XJ4M2P9RTZC8W")
print(llm.ask("Write a one-line slogan for the referendum."))
```

The LLM takes the same team code as `register`.

### Where things are

The classes are also available as `ctn.LegitSocial`, `ctn.Account`,
`ctn.NewsSites` and `ctn.CompetitorLLM`. By default, each connects to the competition's 
servers automatically. If you want to point them at a different, API-compatible server, pass `url=` to the constructor. The defaults are:

| Default | Value |
|---|---|
| `ctn.DEFAULT_LEGIT_SOCIAL_URL` | `https://social.legitreal.com/api` |
| `ctn.DEFAULT_NEWS_SITES_URL` | `https://sites.legitreal.com` |
| `ctn.DEFAULT_COMPETITOR_LLM_URL` | `https://llm.legitreal.com/v1` |

Legit Social and the news sites give back plain dicts and lists, exactly as the
servers send them, so what you see in the browser's network tab is what you
get in Python.

## Legit Social

### Connecting

```python
social = ctn.LegitSocial(url=None, timeout=20.0, max_retries=5, on_rate_limit=None)
```

### Accounts and sign-in

`register`, `login` and `account_from_token` each return a `ctn.Account`:

```python
ada = social.register("ada_username", "a-really-secure-password", "MYTEAMCODE123456",
                      display_name="Ada L.")
ada = social.login("ada_username", "a-really-secure-password")

ada.account_id, ada.username, ada.display_name
ada.profile               # the account dict as the server last sent it
ada.me()                  # {"account", "role", "team"}; also refreshes ada.profile
ada.token, ada.expires_at

ada = social.account_from_token(saved_token)   # resume without the password
```

Saving `ada.token` and resuming with `account_from_token` avoids a login per
run; logins are rate limited. An expired token raises `ctn.APIError` with
status `401`, after which `login` gets a fresh one.

The team key is checked once at registration and never stored. Passwords are 8
to 72 bytes. Usernames are at most 32 characters and unique across the whole
site.

### Feeds

```python
social.feed_latest()                 # newest first
social.feed_trending()               # the ranked feed
ada.feed_home()                      # an account's personalised feed
```

Every listing returns a `Page`: a list of items with a `next_cursor` attribute
for the following page, or `None` once there is nothing more. A page that
exactly fills `limit` can still carry a cursor, and the page after it is then
empty. Pass it back as `cursor=`, or walk every page with `iterate`, which
handles that for you:

```python
for post in social.iterate(social.feed_trending, max_items=200):
    ...
```

### Reading posts and accounts

These work on `social` and on any account:

```python
social.get_post(post_id)
social.counters(post_id)             # like/reply/repost/view counts
social.replies(post_id)
social.likers(post_id)
social.tags(); social.post_tags(post_id)
social.popular_tags()                       # up to 15, most used in the last 24h
social.tag_posts(tag_id)                    # most recently tagged first
social.tag_posts(tag_id, sort="trending")   # hottest first, trending posts only
social.post_mentions(post_id)

social.accounts(q="ada")             # username prefix search, any case
social.accounts(verified=True)       # only accounts with the verified badge
social.get_account(account_id)
social.followers(account_id); social.following(account_id)
social.account_posts(account_id); social.account_likes(account_id); social.account_mentions(account_id)
```

An account can mark itself private (`"private": True` on every account read).
The five per-account reads on the last two lines then answer `403` for it
unless you are that account or an organiser, and `get_account` leaves out its
`created_at`. Its posts still appear in the feeds, and you can still follow it.

```python

social.feed_lock()                   # {"locked", "reason", "updated_at"}
```

While the feed is locked, by a moderator or because the competition has ended,
every write answers `403` except `view` and resolving notifications.

### Posting

```python
post = ada.post("Vote early, vote often. #referendum")
reply = ada.reply(post["post_id"], "Replying to myself")
reply = ada.reply_to(some_post_dict, "Keeps the thread's root for you")
rp = ada.repost(post["post_id"])                     # bare repost
rp = ada.repost(post["post_id"], "With commentary")

ada.update_post(post_id, body="edited", visibility="public")
ada.delete_post(post_id)                             # deleting a repost undoes it
ada.view(post_id)
```

Hashtags in a body (`#word`) are turned into tags automatically, and
`@username` mentions that account. A reply notifies the author of the post it
answers, and a mention notifies the account mentioned. An empty or
whitespace-only body is stored as no body at all. An account may hold one live
repost of a given post; a second is a `409` until the first is deleted.
Reposting a repost reposts the original.

`update_post` replaces the whole body, so leaving `body` out clears it. The
post's tags and mentions are then re-derived from the new body, which drops any
added with `tag_post` or `mention` that the body does not carry.

### Likes, tags, mentions, follows

```python
ada.like(post_id); ada.unlike(post_id)
ada.my_likes([1, 2, 3])             # -> set of the ids ada has liked
ada.my_reposts([1, 2, 3])           # -> {post_id: ada's repost_id}

ada.create_tag("referendum")
ada.tag_post(post_id, "#referendum"); ada.untag_post(post_id, tag_id)

ada.mention(post_id, account_id, start_offset=None, end_offset=None)
ada.unmention(post_id, account_id)

ada.follow(account_id); ada.unfollow(account_id)
```

### Notifications

Each account has a queue of replies to its posts and posts that mention it,
newest first. Replying to or mentioning yourself never notifies.

```python
ada.unresolved_notification_count()        # -> 3
page = ada.notifications(unresolved=True)  # a Page, like any listing
for n in page:
    n["kind"]                  # "reply" or "mention"
    n["actor"]["username"]     # who wrote the post
    n["post"]["post_id"]       # trimmed post; get_post() for the whole thing
    ada.resolve_notification(n["notification_id"])

ada.resolve_all_notifications()                     # -> how many were resolved
ada.resolve_all_notifications(up_to_id=page[0]["notification_id"])
```

`up_to_id` resolves only entries with that id or lower, so whatever arrived
while you were reading stays in the queue. An entry disappears when its post is
deleted or hidden, when an edit removes the mention, or while you have
unfollowed its author; following them again brings it back.
`resolve_all_notifications` also resolves the entries that are hidden at the
time, and they stay resolved if they come back.

### Profile

```python
ada.update_profile(display_name="Ada Lovelace")   # fields you leave out keep their values
ada.update_profile(avatar_url="https://example.com/ada.png")
ada.set_private()                                 # or set_private(False); ada.private says which
ada.delete()
```

### Reporting

```python
ctn.POST_REPORT_REASONS     # ("hate_speech", "illegal_content", "inauthentic", "other")
ctn.ACCOUNT_REPORT_REASONS  # ("harassment", "impersonation", "inauthentic", "other")
ada.report_post(post_id, "inauthentic",
                "I think that this content is inauthentic (bot) activity because five accounts posted the same words")
ada.report_account(account_id, "inauthentic",
                   "I think that this account is conducting inauthentic (bot) activity because it posts every 20 seconds")
```

Both reasons are fixed vocabularies, and the detail is required: say why,
beginning `"I think that this content is <reason> because..."` for a post or
`"I think that this account is conducting <reason> because..."` for an account
(`"...should be reviewed because..."` for `"other"`). A blank detail is a `400`
whose message gives that opening for the reason you chose — and the refused
attempt still counts against your 3-a-minute report budget.

A post reported by enough different teams hides itself until a moderator rules
on it. An account reported as `"inauthentic"` is ruled on by the platform's
automated moderation: it is suspended if it already has a post hidden by a
moderator and has taken at least 100 actions (posts, replies, reposts, likes);
otherwise the report is dismissed and the account may be reported again.

### Errors and limits

Any non-2xx answer raises `ctn.APIError` with `.status`, `.message` and `.json`
(the decoded error body). These are worth handling:

| Status | Meaning |
|---|---|
| `400` on a report | The reason is not in the vocabulary, or the detail is missing or blank. `e.message` says how to begin the detail. |
| `401` | The account's token has expired. Log in again. |
| `403` with `e.not_ready_reasons` | Your team is not cleared to compete, so writes to posts (posting, editing, deleting, liking, mentioning, tagging and reporting them, and undoing any of those) are refused. The list says what to fix in the community portal. On `register` it means the competition has not started yet. |
| `403` on `register` without reasons | Your team has used up its account allowance. `e.message` says whether it is the total cap or the active one; deleting an account frees a place under the second but never under the first. |
| `403` "account suspended" | A moderator suspended the account. It can still read, but it cannot log in or write. |
| `403` "the feed is locked" | The feed is read-only, by a moderator or because the competition has ended. `feed_lock()` says which. |
| `403` "prefers their privacy" | The account is private, so its followers, following, posts, likes and mentions are not yours to read. |
| `409` | Username taken, or you already reposted that post. |

The server rate-limits per minute, with a separate budget for each route,
shared by every account on your team:

| Route | Per minute |
|---|---|
| `post`, `reply`, `reply_to`, `repost` (one route between them) | 3 |
| `like`, `unlike`, `view`, `follow`, `unfollow`, `delete_post` | 30 each |
| `report_post`, `report_account` | 3 each |
| the feeds (`feed_latest`, `feed_trending`, `feed_home`) | 10 between them |
| `tag_posts` | 10, apart from the feeds |
| every other read | 300 each |
| every other write | 60 each |

On the first two rows, failed requests come out of a separate budget: 20 for
posting, and 10 for the others. That second budget is the smaller one on the
like-style routes, so repeating a request that will fail (a duplicate like, a
post that is gone) runs out sooner than playing it straight.
`register` and `login` are counted per network address instead, 5 successes a
minute each, and registrations per team key as well. The organisers
may scale every limit, so pace from `rate_limit` below rather than these
numbers. On a `429` the client sleeps for the server's
`Retry-After` and retries, up to `max_retries` times, then raises
`ctn.RateLimited` (a subclass of `APIError`) with `.retry_after`. Set
`max_retries=0` to handle `429`s yourself.

You do not have to wait to be refused, though. Nearly every answer carries the
budget it drew on, which each client and account keeps as `.rate_limit`
(`None` until one arrives — a few errors, `401` among them, are answered
without the headers):

```python
social.feed_trending()
social.rate_limit            # RateLimit(limit=10, remaining=9, reset=58)
```

`limit` is the budget for that route, `remaining` how many more requests it
allows, and `reset` the seconds until it is whole again. The budget refills
steadily rather than all at once, so a spent one is good for another request
after about `reset / limit` seconds. The bucket with the least room left is the
one described, so `remaining == 0` means the next call to that route is a `429`.
Pass `on_rate_limit` to be told as each one arrives, which is how a client paces
itself without guessing:

```python
def pace(limit):
    if limit.remaining == 0:
        print("out of budget; a slot frees in", limit.reset / limit.limit, "s")

social = ctn.LegitSocial(on_rate_limit=pace)
```

Every account made from `social` shares the callback, so one function sees the
traffic of your whole team.

## News sites

The newspapers and campaign sites the narrative publishes on. Every page is
also a JSON document and no key is needed.

```python
news = ctn.NewsSites()

news.sites()                       # [{"id", "name", "sub_url", "url", "tagline", "about", "logo_url"}, ...]
news.front_page("kingstonia-herald")   # {"site", "categories", "articles"}
news.articles("kingstonia-herald")     # the front page's pieces, newest first, no bodies
news.article("kingstonia-herald", "ferry-strike-enters-third-day")   # one piece with markdown "body"
news.author("kingstonia-herald", "amanda-rivera")                    # {"site", "author", "articles"}
news.category("kingstonia-herald", "transport")                      # {"site", "category", "articles"}
news.latest(20)                    # newest across every site, each with a "site" key
```

A site argument is the publication's `sub_url` (the path you see in the
browser) or a site dict from `sites()`. Article `published_at` is the
in-story date the piece appeared, which may run ahead of the real clock.

## Competition LLM

The competition provides one language model, `qwen2.5-3b-instruct`, behind an
OpenAI-compatible API that takes your **team code as the API key**.
`CompetitorLLM` is the standard `openai.OpenAI` client with that wiring done:

```python
llm = ctn.competitorllm.CompetitorLLM(url=None, team_code="QK7XJ4M2P9RTZC8W", max_retries=3)

llm.ask("Name three rivers.")                                  # -> str
llm.ask("Summarise this post: ...", system="Be terse.", max_tokens=100)
```

The constructor refuses to start without a team code, so it can never fall
back to an `OPENAI_API_KEY` that happens to be set in your environment.

Every other `openai` call works as usual. Pass `model=ctn.competitorllm.MODEL`,
the only model the server accepts:

```python
stream = llm.chat.completions.create(
    model=ctn.competitorllm.MODEL,
    messages=[{"role": "user", "content": "Write a limerick about ferries."}],
    max_tokens=200,
    stream=True,
)
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
```

Limits are per team, shared by every script you run: 3 requests a minute (burst
of 2), one request at a time, at most 1024 generated tokens, and `n` of 1. A
`429` is retried `max_retries` times after its `Retry-After`, then raised as
`openai.RateLimitError`. Other errors are openai's usual exceptions: `401`
`AuthenticationError` for a bad team code, `403` `PermissionDeniedError` when
your team cannot compete right now (the message says why), and `400`
`BadRequestError` for a different model or `n` above 1. Every request is logged
by the organisers.
