Blockchain, Crypto & Web3 in Europe

43 blockchain, crypto & web3 providers across Europe, publishing 128 APIs.

43 providers 128 published APIs 318 indexed documents

Blockchain, Crypto & Web3 across Europe — 43 providers on the APIs.io network sit in both cohorts, and between them they publish 128 indexed APIs.

26 of the 43 publish at least one machine-readable API; 17 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: 17 developing, 11 emerging, 7 minimal, 5 thin, 2 strong, and 1 exemplar.

Leading by rating: Braiins, Ledger, Copper.co, SIX, Silverflow, Safello, and 37 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.
