SubQuery

SubQuery provides Web3 data indexing, RPC, and AI infrastructure that enables developers to access and query blockchain data efficiently. Its platform supports natural language querying through AskSubQuery, which turns conversational questions into real-time blockchain insights without requiring GraphQL, schemas, or complex query writing. The platform connects directly to multiple data sources including SubQuery, The Graph, Covalent, and Codex, transforming complex blockchain schemas into simple conversational answers. SubQuery offers an Indexer SDK for building data indexing applications and supports AI agent integration through MCP (Model Context Protocol). The platform operates on a pay-as-you-go model for developers with credit card payments, while SQT token holders unlock free daily queries. Founded in 2020 and headquartered in New Zealand, the company has raised approximately $13.1 million at the Series A stage.
