Stellar Data: RPC + Horizon

API access for reading chain state. Stellar RPC is the preferred entry point for new projects; Horizon remains for legacy and historical-query workflows. For deeper history beyond RPC's 7-day window, use Hubble/Galexie.

When to use this skill

• Calling Stellar RPC methods (getLatestLedger, getLedgerEntries, getEvents, simulateTransaction, sendTransaction)
• Querying Horizon endpoints (accounts, transactions, operations, effects, ledgers)
• Streaming live events or operations
• Pulling historical data beyond RPC's 7-day window (Hubble, Galexie)
• Choosing between RPC and Horizon for a given workflow
