Pandas API client for CoinGecko

coingecko-pandas

Pandas API client for CoinGecko

A pandas-style Python client for the CoinGecko REST and WebSocket APIs. Every list endpoint returns a pandas.DataFrame, every dict endpoint returns a TypedDict, and every shape is enforced by a pandera schema. Sync + async, with optional Streamlit explorer and FastMCP server extras.

Install

uv pip install coingecko-pandas              # core
uv pip install "coingecko-pandas[ws]"        # + WebSocket
uv pip install "coingecko-pandas[explorer]"  # + Streamlit dashboard
uv pip install "coingecko-pandas[mcp]"       # + FastMCP server
uv pip install "coingecko-pandas[dev]"       # + test/lint toolchain

Quickstart

Sync

from coingecko_pandas import CoinGeckoPandas

with CoinGeckoPandas() as client:
    # Top 10 by market cap
    df = client.coins_markets("usd", per_page=10, page=1)
    print(df[["id", "symbol", "currentPrice", "marketCap"]])

    # Bitcoin OHLC last day
    ohlc = client.coins_id_ohlc("bitcoin", vs_currency="usd", days="1")
    print(ohlc.tail())

Async

import asyncio
from coingecko_pandas import AsyncCoinGeckoPandas

async def main():
    async with AsyncCoinGeckoPandas() as client:
        markets, ohlc = await asyncio.gather(
            client.coins_markets("usd", per_page=10, page=1),
            client.coins_id_ohlc("bitcoin", vs_currency="usd", days="1"),
        )
        print(markets.head())
        print(ohlc.tail())

asyncio.run(main())

Authentication

CoinGecko offers two API tiers. The repo ships an .env.example — copy it to .env, fill in your keys, and any example/test that calls load_dotenv() will pick them up automatically:

cp .env.example .env
$EDITOR .env

Or set them directly in your shell:

# Demo (free) tier
export COINGECKO_DEMO_API_KEY=...

# Pro tier (auto-switches base URL to pro-api.coingecko.com)
export COINGECKO_PRO_API_KEY=...

Or pass via the constructor:

CoinGeckoPandas(api_key="demo-key")
CoinGeckoPandas(pro_api_key="pro-key")

The Pro key takes precedence and switches the base URL to https://pro-api.coingecko.com/api/v3/. The client reads env vars in __post_init__, so as long as .env is loaded before instantiation, you don't need to pass anything explicitly.

Endpoints

All 41 CoinGecko Demo API endpoints are exposed across 14 mixin classes (one per OpenAPI tag):

Mixin	Methods
PingMixin	ping_server
SimpleMixin	simple_price, simple_token_price, simple_supported_currencies
CoinsMixin	coins_list, coins_markets, coins_id, coins_id_tickers, coins_id_history, coins_id_market_chart, coins_id_market_chart_range, coins_id_ohlc
ContractMixin	coins_contract_address, contract_address_market_chart, contract_address_market_chart_range
AssetPlatformsMixin	asset_platforms_list, token_lists
CategoriesMixin	coins_categories_list, coins_categories
ExchangesMixin	exchanges, exchanges_list, exchanges_id, exchanges_id_tickers, exchanges_id_volume_chart
DerivativesMixin	derivatives_tickers, derivatives_exchanges, derivatives_exchanges_list, derivatives_exchanges_id
NFTsMixin	nfts_list, nfts_id, nfts_contract_address
ExchangeRatesMixin	exchange_rates
SearchMixin	search_data
TrendingMixin	trending_search
GlobalMixin	crypto_global, global_defi
PublicTreasuryMixin	entities_list, public_treasury_entity, public_treasury_transaction_history, public_treasury_entity_chart, companies_public_treasury

WebSockets (Pro tier)

CoinGecko publishes 4 channels (Pro only):

Method	Channel	Code
subscribe_simple_price	CGSimplePrice	C1
subscribe_onchain_token_price	OnchainSimpleTokenPrice	G1
subscribe_onchain_trade	OnchainTrade	G2
subscribe_onchain_ohlcv	OnchainOHLCV	G3

from coingecko_pandas import CoinGeckoPandas, CoinGeckoWebSocket

client = CoinGeckoPandas(pro_api_key="...")
ws = CoinGeckoWebSocket.from_client(client)

with ws.subscribe_simple_price(coins=["bitcoin"]) as session:
    ...

The exact WebSocket connection URL and subscribe payload format are not in the public docs at the time of generation. Verify against the CoinGecko Pro dashboard before relying on this in production.

Error handling

from coingecko_pandas import (
    CoinGeckoAPIError,
    CoinGeckoAuthError,
    CoinGeckoRateLimitError,
)

try:
    df = client.coins_markets("usd")
except CoinGeckoAuthError:
    ...
except CoinGeckoRateLimitError:
    ...
except CoinGeckoAPIError as e:
    print(e.status_code, e.url, e.detail)

Development

uv pip install -e ".[dev]"
uv run pytest tests/test_unit.py tests/test_async_unit.py -v
uv run ruff check coingecko_pandas
uv run mypy coingecko_pandas

CI runs the same checks on every push and PR via .github/workflows/ci.yml across Python 3.11, 3.12, and 3.13.

To run the live integration tests:

PYTEST_LIVE=1 uv run pytest tests/test_integration.py -v

Releasing

Releases are cut by pushing a v* tag. .github/workflows/release.yml then:

1. Builds sdist + wheel via uv build
2. Publishes to PyPI via trusted publishing (OIDC, no API token in secrets)
3. Creates a GitHub release with the built artifacts attached

One-time setup (before the first release):

1. Reserve the coingecko-pandas name on PyPI.
2. Visit https://pypi.org/manage/account/publishing/ and add a pending publisher:
   • PyPI project name: coingecko-pandas
   • Owner: sigma-quantiphi
   • Repository: coingecko-pandas
   • Workflow: release.yml
   • Environment: pypi
3. In the GitHub repo settings, create an Environment named pypi.

To cut a release:

# 1. Move [Unreleased] entries under a new version header in CHANGELOG.md
# 2. Bump version in pyproject.toml
# 3. Commit, tag, push
git commit -am "Release v0.1.1"
git tag v0.1.1
git push origin main --tags
