Cardano Stake Pool API
Cardano's stake-pool operators (SPOs) — live from the public Koios indexer, no key. Cardano is delegated proof-of-stake: ADA holders delegate to stake pools run by independent operators, who mint blocks and earn rewards. The Cardano account reader resolves which pool a single stake account delegates to, but there is no registry of the pools themselves. This opens it. List every pool the chain knows with its operator margin, fixed cost and pledge; look up one pool in full — its registered identity (ticker, name, homepage, description) from off-chain metadata plus its on-chain economics: live delegated stake, saturation, delegator count, lifetime blocks and status; and read a pool's Mark / Set / Go stake snapshots, the three-epoch pipeline Cardano uses to compute rewards. The operator layer for Cardano wallets, staking dashboards, pool explorers and analytics. Distinct from the Cardano account reader (per-account delegation), the chain-economics reader, the native-token registry and the DRep governance reader. Live from the indexer; short cache only.
