Blockchain, Crypto & Web3 in Europe

36 blockchain, crypto & web3 providers across Europe, publishing 77 APIs.

36 providers 77 published APIs 264 indexed documents

Blockchain, Crypto & Web3 across Europe — 36 providers on the APIs.io network sit in both cohorts, and between them they publish 77 indexed APIs.

22 of the 36 publish at least one machine-readable API; 14 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 14 developing, 7 emerging, 7 minimal, 3 strong, 3 thin, and 2 exemplar.

Leading by rating: FeedOracle Technologies, AlgoVoi, Braiins, Ledger, Copper.co, Silverflow, and 30 more.

Region membership is derived from three explicit signals — a provider tag, a provider-name pattern, or a stated headquarters in the provider’s own description. This is a map of stated headquarters, not of markets served.
