tradernick-data-provider

Python client for the TraderNick data_provider service. Drop-in compatible with horatio-data-provider: same DataProviderClient class, same namespaces (evm, tron, btc, binance, hyperliquid, wallets, cache, jobs), same chainable builder methods, same as_pandas() / as_polars() / as_parquet() terminators. The only visible difference is the import path.

# Before
from horatio_data_provider import DataProviderClient

# After
from tradernick_data_provider import DataProviderClient

The server URL passed to the constructor is the only thing you need to change at the call site.

Install

pip install tradernick-data-provider

Usage

import asyncio
from tradernick_data_provider import DataProviderClient

async def main():
    async with DataProviderClient("http://localhost:10005") as client:
        df = await client.binance.ohlcv("BTC", "1h") \
            .time_range("2026-06-01T00:00:00Z", "2026-06-08T00:00:00Z") \
            .as_polars()
        print(df)

asyncio.run(main())

All Horatio query builders work unchanged. The server delegates to ClickHouse instead of DeFiStream, so reads stay sub-second on tables where Horatio has to pay a fresh upstream fetch.

Status

0.5.0 — Binance spot markets + erc20 min_amount fix + first test suite.

• client.binance.spot.{ohlcv, raw_trades} — the Binance spot market, a fully separate dataset from perp/futures. Same shapes as the perp binance.{ohlcv, raw_trades}; raw_trades keeps add_symbol / with_id.
• Fix: evm.erc20.transfers([...]).min_amount(x) now resolves server-side. The client routed .min_amount() to /evm/erc20_transfers/read/min, but that alias was never registered on the server (it 404'd). erc20 is now in the /read + /read/min alias set alongside native/tron/btc transfers.
• Tests: a pytest suite (clients/tests/) — respx-mocked unit tests for body/path construction + response transforms, plus an env-gated live integration tier (-m integration, needs DATA_PROVIDER_URL).

0.4.0 — Transfer wallet selection + multi-network as_parquet lands.

• All transfer queries (evm.erc20, evm.native_transfers, tron.native, tron.trc20, btc.native) now accept full Horatio wallet-selection pushdown: sender_label / receiver_label / involving_label, sender_category / receiver_category / involving_category, and every exclude_* variant.
• query.network([...]).as_parquet(key) now works for all transfer queries — server-side fan-out across networks, in-process concat, single parquet under key. Optional with_network column auto-toggles on multi-network calls.
• Breaking: evm.stader / evm.threshold namespaces removed. TN doesn't ingest those upstreams; the stubs were giving false-positive "namespace exists" signals. Re-add when TN ingestion picks them up.

0.3.0 — Phase 4 TN-exclusive protocols. Adds Spark, Morpho, and Aerodrome (concentrated + basic). New namespaces live under client.evm.{spark, morpho, aerodrome}; existing aave / uniswap / lido / erc20 / native paths are unchanged.

0.2.0 — Phase 1+2 read parity. Validated against horatio-data-provider on 2026-06-07:

• Column-shape parity: 100% across binance / aave / lido / uniswap / hyperliquid / transfers.
• Row-count + value parity: exact match on stable tables (binance.ohlcv 1m, raw_trades, lido.deposit, aave.borrows/repays, evm.native with min_amount); within ±2 rows on AAVE event tables where DeFiStream's sweep loop occasionally re-fetches windows with slightly different cuts.

What works:

• binance.{ohlcv, raw_trades, book_depth, open_interest, funding_rate, long_short_ratios} (with with_id, add_symbol)
• binance.spot.{ohlcv, raw_trades} — spot market (separate from perp)
• maintenance: binance.{flush,compact}_{raw_trades,ohlcv,exchange}, client.cache.{flush, compact, dedup, migrate_time}, client.jobs.{list, get, cancel, wait, submit}
• evm.aave.{deposit, withdraw, borrow, repay, flashloan, liquidation} with involving, exclude_involving, eth_market_type
• evm.uniswap.{swap, deposit, withdraw, collect} — V3
• evm.lido.{deposit, withdrawal_request, withdrawal_claimed, l2_deposit, l2_withdrawal_request}
• evm.erc20.transfers, evm.native_transfers with full filter set (sender / receiver / involving / exclude_* / min_amount / max_amount)
• tron.{native, trc20}.transfers, btc.native.transfers
• hyperliquid.{ohlcv, trades, fills, funding, transfers, vaults, trade_history, position_history}
• client.{wallets.list, wallets.get, wallets.upsert, wallets.delete}
• client.{load_parquet, scan_parquet, list_snapshots, delete_snapshot, as_parquet} — server-side parquet snapshots with local_* filters
• client.jobs.{list, get, cancel} — proxies to the ingestion job queue

TN-exclusive (since 0.3.0):

• evm.spark.{deposits, withdrawals, borrows, repays, flashloans, liquidations} — same six-event surface as evm.aave byte-for-byte
• evm.morpho.{supplies, withdrawals, borrows, repays, supply_collaterals, withdraw_collaterals, liquidations} with .market_id(...) filter
• evm.aerodrome.concentrated.{swaps, deposits, withdrawals, collects} with optional tick_spacing
• evm.aerodrome.basic.{swaps, deposits, withdrawals, claims} with optional stable flag

Not yet exposed / unsupported:

• .aggregate(...) — present on every builder (Horatio parity) but the server has no aggregate read route, so it 404s. Aggregate client-side from the raw .as_polars() frame for now; a server-side aggregate is a future release.
• client.btc.mined() — no server route/table yet (TN doesn't ingest Bitcoin coinbase payouts); calling it 404s.
• evm.{stader, threshold} — dropped in 0.4.0 (TN doesn't ingest the upstream yet); re-add when ingestion lands
• gmx.* namespace — not planned (out of scope for this platform)
• hyperliquid.{sends, spot_transfers} — exposed but hollow: DeFiStream provides them ("Tier 3") but TN doesn't ingest them yet, so the endpoints return the correct empty schema (0 rows). A follow-up will add the CH tables
  • ingestion streams and make them return real data.
• client.scan_parquet only honors address-based local_* filters; label/category/entity variants are wired but no-op without wallet_labels co-mounted on the snapshot.

Compatibility

Drop-in compatible with horatio-data-provider 4.x.
