{"openapi":"3.1.0","info":{"title":"Stellar (XLM) On-Chain API","version":"1.0.0","description":"Live on-chain data from the Stellar network, the open blockchain for payments and asset issuance behind the lumen (XLM), served straight from Stellar's public Horizon API — no key, nothing cached. The account endpoint returns any address's full wallet: its XLM balance and every issued asset it holds — Stellar is the home of anchored stablecoins like USDC, so a wallet shows native lumens alongside its tokens, each with the asset code, issuer and balance — plus the account sequence, sub-entry count and home domain. The payments endpoint returns the account's most recent payments in and out, each with the counterparty, asset, amount and time. The transactions endpoint returns the account's recent transactions with the ledger, fee, operation count, success flag and memo. The network endpoint returns the live state of the network itself: the latest ledger, the base fee and the fee percentiles and ledger capacity that tell you how congested the network is. Everything is read live from Horizon, nothing stored. This is the Stellar on-chain layer for any wallet, anchor, exchange, payments or analytics app. Distinct from the XRP Ledger, EVM and Solana on-chain APIs and from price feeds — this is Stellar account state, multi-asset balances, payments and network health. 4 endpoints, no key on our side.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/stellar-api","description":"oanor
