🇬🇧Blockchain, Crypto & Web3 in United Kingdom

7 blockchain, crypto & web3 providers in United Kingdom, publishing 18 APIs.

7 providers 18 published APIs 18 indexed documents

Blockchain, Crypto & Web3 in United Kingdom — 7 providers on the APIs.io network sit in both cohorts, and between them they publish 18 indexed APIs.

4 of the 7 publish at least one machine-readable API; 3 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: 3 developing, 2 emerging, 1 thin, and 1 minimal.

Leading by rating: Trust Payments, Cardstream, Thredd, Thought Machine, Globacap, Zilch, and 1 more.

Country membership is exact-tag only. A provider lands in United Kingdom when one of its own top-level tags names the country — there is no headquarters signal on the country axis, unlike the region axis which reads tag, provider-name pattern, and stated HQ. So this cell is a floor, not a census, and it understates by construction — a blockchain, crypto & web3 company headquartered in United Kingdom that never tags itself is counted nowhere on this axis. The region cuts read the wider signal set and will generally hold more.

This page is the intersection of two independently computed cohorts: United Kingdom and Blockchain, Crypto & Web3. A provider appears here only when it is already a member of both. United Kingdom membership is matched on tag, so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
