# Dapper Labs — Flow blockchain developer surface

> Dapper Labs is the creator of the Flow blockchain and consumer NFT experiences (NBA Top Shot, NFL All Day, Disney Pinnacle). Its primary public developer surface is the Flow Access API — a public, unauthenticated node API (REST + gRPC + WebSocket streaming) for reading on-chain data and submitting Cadence transactions. This llms.txt is generated by the API Evangelist enrichment pipeline from the catalog and repo artifacts.
