**APIs profiled:** 1

Flipside Crypto is a blockchain analytics platform that lets analysts and developers run SQL queries against curated, Snowflake-backed on-chain datasets covering Ethereum, Solana, and 20+ other chains. The Data API exposes query execution and result retrieval over a JSON-RPC-style HTTP interface at api-v2.flipsidecrypto.xyz, authenticated with an x-api-key. In May 2026 Flipside sold its blockchain data business to SonarX and refocused on its edisyl enterprise AI platform; this catalog documents the Flipside Data API as published.
