**Canonical:** https://apis.io/providers/blockspring/  
**Website:** https://blockspring.com  
**APIs profiled:** 0

Blockspring was a data integration and enrichment platform that let developers and spreadsheet users run cloud functions and connect to hundreds of third-party APIs and data services from Google Sheets, Excel, and via its own API. Founded around 2014 and originally Y Combinator backed, it was acquired by Coda (Krypton) in 2017 and surfaced here as an a16z portfolio-associated company. All Blockspring services -- the website tooling, integrations, plugins, APIs, and data enrichment -- were permanently shut down on December 29, 2022, with active subscriptions cancelled and prorated refunds issued. This profile is retained as a historical record; there is no live developer surface, OpenAPI, SDK, or documentation to enrich.
