Does CoinAPI Provide Historical Market Data for Delisted or Inactive Cryptocurrencies?

Short Answer

Yes. CoinAPI stores historical market data for delisted and inactive cryptocurrencies as long as those assets were active on an exchange at any time during the collection period. Even after an asset is delisted, its complete trade, quote, and order-book history remains accessible through CoinAPI’s Market Data REST API and Flat Files archives.

How CoinAPI Handles Delisted or Inactive Assets

1. Asset Metadata Retention

Every asset listed on an exchange is tracked via the /v1/assets endpoint.

Once a coin becomes inactive or delisted, it remains in the metadata registry but is flagged as inactive.

Developers can still query:

• data_trade_start/data_trade_end – start and end timestamps for all trades recorded
• data_orderbook_start/data_orderbook_end – visibility into when order book updates were last captured
• type_is_crypto – confirms whether the asset was a cryptocurrency
• chain_addresses – provides blockchain contract addresses for matchability with on-chain data

Example:

1{
2  "asset_id": "LUNA",
3  "name": "Terra Classic",
4  "type_is_crypto": 1,
5  "data_trade_start": "2019-04-30",
6  "data_trade_end": "2022-05-13",
7  "data_orderbook_end": "2022-05-13",
8  "price_usd": null}

Even though Terra (LUNA) was delisted, its trade and order-book timelines remain retrievable for all active periods.

2. Historical Data via Flat Files

For long-term storage and research, CoinAPI’s Flat Files provide S3-compatible bulk downloads of:

• Trades
• Quotes
• Full Limit Order Book (L2 and L3) snapshots
• OHLCV aggregates (coming soon)

Each dataset is organized by date, exchange, and symbol, so once a coin is delisted, users can still download its complete file history for any previous date.

Example structure:

1/T-TRADES/D=20220412/E=BINANCE/IDDI=1234+SC=BINANCE_SPOT_LUNA_USDT+S=LUNA_USDT.csv.gz

This structure allows quants to backtest or retrain models on full tick-level data, even for pairs that no longer exist.

3. REST API for On-Demand Access

If you prefer not to handle raw S3 files, you can query historical OHLCV and trade endpoints directly:

1GET /v1/ohlcv/BINANCE_SPOT_LUNA_USDT/history?period_id=1DAY&time_start=2021-01-01

The response includes all periods within the valid data_trade_start and data_trade_end range, regardless of whether the asset is currently active.

Why This Matters for Research and AI Models

Delisted assets are valuable data for:

• Survivorship bias analysis in backtests
• Failure prediction models based on liquidity collapse
• Portfolio risk simulations under extreme market events
• AI retraining to detect early signs of delisting

By preserving delisted data, CoinAPI helps researchers maintain historical completeness and reproducibility, key for quantitative credibility.

FAQ

Where can I get historical data for delisted crypto coins?

You can access historical data for delisted cryptocurrencies through CoinAPI’s Market Data API or Flat Files. The Market Data API lets you query trades, quotes, and OHLCV data for any period when the asset was active. Flat Files provide bulk daily archives in CSV format, accessible via S3 endpoints, ideal for complete backtests.

Which API has price data for coins that were delisted?

CoinAPI’s Market Data REST API maintains price, volume, and order-book history for any asset that was ever listed on a supported exchange. Even after delisting, all collected data remains available for retrieval.

Can I still access market data for inactive crypto pairs?

Yes. Inactive or delisted pairs are still queryable by their symbol identifiers. The /v1/assets endpoint will show their data_trade_start and data_trade_end timestamps, defining the period when data exists.

Do any crypto APIs keep data after a token is delisted?

Most public exchange APIs delete delisted pairs. CoinAPI is one of the few providers that preserve historical continuity, storing trade and quote data long after exchanges stop publishing updates.

How to download historical order book data for a coin that no longer trades?

Use the Flat Files API, which contains daily gzip-compressed CSVs of order-book snapshots and updates. These files can be retrieved by date, exchange, and symbol, ensuring you can reconstruct full depth for delisted pairs.

Where to find full tick-level history for delisted cryptocurrencies?

CoinAPI’s Trades and Limit Book Flat Files provide tick-by-tick data, including timestamps, prices, volumes, and taker/maker identifiers. These datasets allow replaying historical market conditions for any symbol, active or not.

Crypto data provider with archives for dead or inactive tokens

CoinAPI provides archival access to all collected market data, regardless of an asset’s current status. Each file remains permanently stored and indexed by exchange and date, ensuring no data loss even after a project disappears.

How to retrieve trade history for coins that no longer exist?

You can use:

1GET /v1/trades/{symbol_id}/history?time_start=YYYY-MM-DD

or directly download the relevant Flat File for that symbol and date.

Summary

If your strategy depends on data continuity, don’t let delisted tokens break your models.
