What is the CoinLore API?

CoinLore is a free cryptocurrency market data API requiring no API key or registration, providing prices, market capitalisation, trading volume, supply figures and percentage changes for more than 10,000 coins.

CoinLore is the most permissive free crypto API still operating — no key, no signup, and limits generous enough for real use. That matters because most competitors have progressively tightened their free tiers.

One thing to watch: numeric values are returned as strings, including prices and percentage changes. Parse them explicitly, and use decimal arithmetic rather than binary floats for anything involving money.

Common errors and how to fix them

Numbers arrive as strings

All numeric fields are JSON strings.

Fix: Parse explicitly, and use a decimal type for monetary values rather than a binary float.

Empty array for an unknown id

Coin ids are CoinLore-specific integers, not ticker symbols.

Fix: Fetch /tickers/ once to map symbols to ids and cache it.

Requesting faster than about one per second.

Fix: Throttle and cache; prices rarely need sub-second freshness.

CoinLore API — frequently asked questions

Does CoinLore need an API key?

No — no key, no registration and no signup, which makes it the most permissive free crypto API currently available.

Why are prices returned as strings?

To preserve decimal precision. Parse them explicitly and use decimal arithmetic for money; converting to a binary float can introduce rounding errors.

How do I find a coin's id?

Ids are CoinLore-specific integers, not ticker symbols. Fetch /tickers/ once to build a symbol-to-id map and cache it — Bitcoin is id 90.

How does it compare with CoinGecko?

CoinGecko has richer data and better documentation but a tighter unauthenticated rate limit. CoinLore is simpler and more permissive, which makes it a good fallback.
