🇸🇬Blockchain, Crypto & Web3 in Singapore
11 blockchain, crypto & web3 providers in Singapore, publishing 19 APIs.

Blockchain, Crypto & Web3 in Singapore — 11 providers on the APIs.io network sit in both cohorts, and between them they publish 19 indexed APIs.
7 of the 11 publish at least one machine-readable API; 4 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: 4 thin, 2 developing, 2 minimal, 1 strong, and 1 emerging.
Leading by rating: Biconomy, Sygnum, Aelf, EDX Markets, Blue Square Group Limited, ADDX, and 5 more.
Country membership reads a tag or a stated headquarters. A provider lands in Singapore when one of its own top-level tags names the country, or when its own description states a headquarters that names the country or one of its cities (roadmap#542, #719). A description that calls a company by its nationality, or names a city in a phrase that is not a headquarters statement, is not counted, so this cell is a floor, not a census.

This page is the intersection of two independently computed cohorts:
Singapore and
Blockchain, Crypto & Web3. A provider appears here only when it is
already a member of both. Singapore membership is matched on tag, stated HQ,
so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.
Work with this as data
Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
