0xinsider Python SDK

Official Python client for the 0xinsider Developer API: Polymarket sports and esports analytics, wallet grades, large trades, positions, reports and sharp-money flow.

pip install 0xinsider

The distribution is 0xinsider; the import is oxinsider, because a Python module name cannot start with a digit.

Try it without a key

The sandbox answers every documented operation with example data. It needs no credential and never touches production data.

import oxinsider

with oxinsider.Client.sandbox() as client:
    page = client.list_leaderboard(limit=5)
    print(page["data"][0]["username"])

    # Any error the operation documents, on demand:
    try:
        client.request("GET", "/api/v1/leaderboard", query={"sandbox_status": 429})
    except oxinsider.RateLimitedError as error:
        print(error.code, error.retry_after)

Live data

Data operations need an API key from 0xinsider.com/developers or an OAuth 2.1 access token (auth.md), plus an active Pro subscription. Discovery, health and platforms are public.

import oxinsider

client = oxinsider.Client()  # reads OXINSIDER_API_KEY
trader = client.get_trader("swisstony", expand=["strategy", "categories"])
print(trader["data"]["grade"])

for trade in client.paginate("list_whale_trades", min_grade="A", limit=100):
    print(trade["size_usd"], trade["market"]["title"])

• Every documented operation is a method named after its operationId in snake_case (listLeaderboard becomes list_leaderboard). Each returns the decoded JSON body.
• if_none_match="<etag>" returns {"object": "not_modified", "data": None, "etag": ...} when nothing changed.
• idempotency_key= is accepted on the webhook mutations that document it.
• The SSE stream is read with client.request("GET", "/api/v1/stream", stream=True), which returns the open httpx.Response.

Errors

Every non-2xx response raises oxinsider.OxinsiderApiError or a subclass: BadRequestError, AuthenticationError, SubscriptionRequiredError, PermissionDeniedError, NotFoundError, RateLimitedError or ServerError. Each carries status, code, reason, param, retry_at, retry_after and request_id. Branch on reason when it is present. For RateLimitedError, wait retry_after seconds. A request that gets no response raises OxinsiderConnectionError.

How it is built

src/oxinsider/_operations.py is generated from the published OpenAPI document by scripts/generate.py, and a weekly workflow opens a pull request when the contract changes. Releases publish to PyPI from GitHub Actions through trusted publishing.
