Products are the Portal API for HTTP streaming of raw chain data, a decentralized data lake run by worker nodes, a TypeScript SDK and managed Cloud. Solana is among supported networks. The public endpoint is free for development, zero egress fees are listed, and dedicated portals and higher limits need a paid plan without stated prices. The stack is described as open source with self-hosting, Portal being Rust under AGPL-3.0. Performance figures such as 27ms P50 are vendor-reported.
