Marinade API

healthy 3,218 Subscribers

Live data from Marinade, Solana's largest liquid-staking protocol, where users stake SOL and hold mSOL (a reward-accruing token) or use Marinade Native. The overview endpoint returns the headline state — the mSOL/SOL price, the 30d and 7d staking APY, and the total value locked. The tvl endpoint returns the full TVL breakdown (staked SOL/USD, liquidity, directed, native, self and select stake). The apy endpoint returns the mSOL staking APY over 30d and 7d with the underlying price evolution. The validators endpoint returns Marinade's delegation validator set ranked by stake — each with its name, vote account, data-centre location, commission, activated stake, average APY and uptime. Read live from Marinade, nothing stored. This is Marinade's own Solana liquid-staking, mSOL-yield, TVL and validator layer — distinct from Ethereum staking feeds, on-chain explorers and DEX/price APIs.

 Solana Program API — oanor API marketplace

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.
