Solana Developer Docs

Two endpoints to build on Solana: a fast RPC + WebSocket for on-chain reads, transactions, and live updates, and a REST Data API for ready-made market data — prices, candles, trades, holders, launches, trending. Both API-key-gated over TLS.

All endpoints live over HTTPS / WSS

What you get

Solana RPC — standard Solana JSON-RPC + WebSocket. Read balances/accounts, simulate & send transactions, subscribe to live updates. Drop-in for any Solana SDK.
Data API — a clean REST API (think Bitquery) for launchpad/DEX data (Raydium LaunchLab today). One endpoint per resource, JSON in / JSON out — no SQL or chain-decoding required.

Use the RPC for chain actions (send a swap, check a balance, watch an account) and the Data API for analytics (price, candles, trades, holders, trending, launches).
