sub2api

sub2api is a Python client for the shared user-facing panel API exposed by Sub2API instances. One client object represents one user's in-memory dashboard session. Requests use curl_cffi with Chrome browser impersonation by default.

The library targets operations present on standard Sub2API deployments: account balance, platform quotas, usage history and statistics, API keys, groups, subscriptions, announcements, and redemption.

Install

pip install sub2api

Python 3.10 or newer is required.

Authenticate with an existing session

The dashboard's access token is different from an sk-... gateway API key. Browser deployments normally store the panel tokens under auth_token and refresh_token in local storage.

import os

from sub2api import Sub2API

client = Sub2API(
    "https://sub2api.example.com",
    access_token=os.environ["SUB2API_ACCESS_TOKEN"],
    refresh_token=os.environ.get("SUB2API_REFRESH_TOKEN"),
)

print(client.me().email)
print(client.balance().balance)

Pass either the instance origin or its full /api/v1 URL. Tokens are retained only in memory. If a refresh token is supplied, the client rotates the token pair after an authenticated 401. Supplying expires_at as a Unix timestamp also enables proactive refresh.

The default browser fingerprint is Chrome. Choose another curl_cffi fingerprint or configure proxies by supplying your own curl_cffi.requests.Session:

from curl_cffi import requests

session = requests.Session(impersonate="safari")
client = Sub2API("https://sub2api.example.com", session=session)

Log in with email and password

from sub2api import Sub2API

with Sub2API("https://sub2api.example.com") as client:
    user = client.login("person@example.com", "password")
    print(user.username)
    print(client.is_authenticated)

An instance with CAPTCHA enabled requires the corresponding proof:

client.login(
    "person@example.com",
    "password",
    turnstile_token="captcha-proof",
)

For a TOTP-enabled account, login() raises TwoFactorRequired and retains the temporary challenge in memory:

from sub2api import Sub2API, TwoFactorRequired

client = Sub2API("https://sub2api.example.com")

try:
    client.login("person@example.com", "password")
except TwoFactorRequired:
    client.complete_2fa("123456")

Common operations

Resources are callable for their common list operation and also expose explicit methods.

balance = client.balance()
quotas = client.account.platform_quotas()

groups = client.groups()
group_rates = client.groups.rates()

first_page = client.keys(page_size=50, status="active")
for api_key in first_page:
    print(api_key.id, api_key.name, api_key.group.name)

all_keys = client.keys.all()
resolved = client.keys.with_group_multipliers()
for item in resolved:
    print(
        item.api_key.key,
        item.group_id,
        item.base_multiplier,
        item.custom_multiplier,
        item.effective_multiplier,
    )

multiplier_by_key = client.keys.multiplier_map(key_by="key")
multiplier_by_id = client.keys.multiplier_map(key_by="id")

created = client.keys.create("automation", group_id=groups[0].id)
client.keys.update(created.id, name="nightly automation")
client.keys.set_status(created.id, active=False)
client.keys.delete(created.id)

all() follows pagination until every key has been fetched. with_group_multipliers() joins each key to its group and reports the base, user-specific, and effective rate; the user-specific rate from /groups/rates takes precedence. multiplier_map() returns the effective rate keyed by the API key value, key ID, or name. Name collisions raise an error instead of silently overwriting an entry.

API key values are available through api_key.key, but object representations redact fields that commonly contain credentials.

Usage history

history and usage refer to the same resource.

from datetime import date, timedelta

end = date.today()
start = end - timedelta(days=7)

page = client.history(
    start_date=start,
    end_date=end,
    page_size=100,
    sort_by="created_at",
    sort_order="desc",
)

for record in page:
    print(record.created_at, record.model, record.actual_cost)

for record in client.history.iter(page_size=100):
    process(record)

stats = client.usage.stats(start_date=start, end_date=end)
dashboard = client.usage.dashboard()
trend = client.usage.trend(start_date=start, end_date=end, granularity="day")
models = client.usage.models(start_date=start, end_date=end)
snapshot = client.usage.snapshot(start_date=start, end_date=end)

Other shared resources

active_subscriptions = client.subscriptions(active=True)
announcements = client.announcements()
client.announcements.mark_read(announcements[0].id)

result = client.redeem("REDEMPTION-CODE")
redemption_history = client.redeem.history()

Fork-specific endpoints

request() provides the same authentication, envelope handling, timezone parameter, refresh behavior, and error mapping for relative endpoints that are not part of the stable resource API.

result = client.request("GET", "some-fork-specific-endpoint")

Absolute URLs and parent-path traversal are rejected so a session token cannot be redirected outside the configured API root.

Errors

HTTP and Sub2API envelope failures use typed exceptions:

from sub2api import AuthenticationError, RateLimitError, Sub2APIError

try:
    client.keys.create("automation")
except RateLimitError as error:
    print(error.retry_after)
except AuthenticationError:
    client.login("person@example.com", "password")
except Sub2APIError as error:
    print(error)

Remote plaintext HTTP is rejected by default because it exposes login credentials and tokens. Localhost HTTP is allowed for development; other HTTP instances require allow_insecure=True.
