Solana Validators & Staking API

Who secures Solana and how decentralised it is, read straight from a public Solana RPC node. Solana is proof-of-stake: validators vote with the SOL delegated to them, and the distribution of that stake decides both rewards and security. The validators endpoint ranks validators by activated stake, with each one's stake in SOL, its share of total stake, its commission and whether it is delinquent (currently failing to vote). The staking endpoint returns the staking economics — total active stake, the circulating and total SOL supply, the percentage of supply that is staked, the current inflation rate broken into its total, validator and foundation components, and the current epoch with its progress. The centralization endpoint computes the stake-centralisation metrics — the Nakamoto coefficient (the fewest validators that together control more than one third of the stake, the amount that could halt the chain under Byzantine-fault-tolerant consensus), the top-10 and top-20 stake share, and the Herfindahl concentration index. This is the Solana validator, staking and decentralisation data-cut, distinct from the Solana on-chain account/transaction API and the other staking and exchange APIs in the catalogue. Live from a public RPC, no key on the upstream, nothing stored.

Pacifica Perpetuals DEX API
Live market data for Pacifica, the Solana-based perpetuals DEX, with no key. List every perpetual market with its contract specs; pull an all-market price feed with mark/mid/oracle price, funding rate, open interest and 24h volume per symbol; read the live order book; and stream recent public trades.

Solana Program API
Inspect deployed Solana programs live from public Solana RPC — no key — and answer the question that matters most for safety: can this program still be changed, and by whom? For any program address it resolves the loader it runs under, whether it is executable, its on-chain ProgramData account, the upgrade authority (or that it has been made immutable / frozen), and the slot it was last deployed at. A batch endpoint audits up to twelve programs at once — perfect for checking the upgrade authority of every program a protocol depends on before you trust it — and a loaders endpoint documents Solana's program loaders. Distinct from balance, token and transaction APIs: this is the program and upgrade-authority layer that auditors, wallets and security tooling rely on to judge whether a Solana program is safe. Live from the chain; short cache only.
