  description: High-performance Solana JSON-RPC HTTP endpoints served from a fault-tolerant elastic-node architecture across
    four global regions (Northern Virginia, Oregon, London, Singapore). Supports the full standard Solana RPC method surface
    (getAccountInfo, getBalance, getTransaction, sendTransaction, getProgramAccounts, getSignaturesForAddress, etc.) with
    credential-level rate limits, per-method routing rules, and observability (detailed logging, performance metrics, usage
    insights).

  description: ChainStream is Syndica's real-time Solana data streaming API. It consolidates updates from multiple validators
    using a "fastest wins" strategy so the subscriber benefits from the lowest-latency notification across the validator set,
    and offers an optional `verified` parameter that delivers only transactions confirmed by multiple validators at `processed`
    commitment. ChainStream uses JSON-RPC 2.0 over WebSocket (`wss://chainstream.api.syndica.io/api-key/<API_KEY>`) and supports
    `transactionsSubscribe`, `slotsSubscribe`, and encoded `blocksSubscribe` against `solana-mainnet` (devnet coming). Production
    users have cut limit-order time-to-fill from 10s to 300ms with it.
