Stellar Asset API

healthy 3,710 Subscribers

Read live data on Stellar assets and the native Stellar DEX, straight from the public Horizon API — no key. Resolve any issued asset (code plus issuer) to its on-chain stats: total authorized supply, number of holding accounts, claimable-balance, liquidity-pool and Soroban-contract amounts, the authorization flags (auth required, revocable, clawback) that tell you how tightly the issuer controls it, and its Soroban contract id. List every issuer of an asset code to survey them and spot impersonators — anyone can issue an asset with any code, so verifying the exact issuer matters. And pull the live order book for an asset against XLM (or any counter asset) on Stellar's built-in decentralized exchange — best bid, best ask and the spread. Distinct from account-, payment- and transaction-level APIs: this is the asset-and-market layer for Stellar wallets, anchors, stablecoin issuers and trading tools. Live from the network; short cache only.

Stellar DEX (SDEX) Order Book & Trades API — oanor API marketplace

Stellar DEX (SDEX) Order Book & Trades API

The Stellar Decentralized Exchange (SDEX) central-limit order book, live from the public Stellar Horizon API — no key, nothing cached. Where the pools reader covers Stellar's AMM and the asset reader covers token metadata, this surfaces the on-chain order book the others miss. Pull the live bids and asks for any asset pair with their price and amount, plus the derived best bid, best ask, mid price and spread. Get a compact ticker for a pair — best bid/ask, mid, spread and the last executed trade. And read the most recent executed trades, network-wide or filtered to a single pair, with their price and base/counter amounts. Defaults to the deeply-traded XLM/USDC pair; quote any pair by passing the selling and buying assets (asset code plus issuer, or XLM for native). The order-book-and-trading layer for Stellar wallets, swap UIs, market-makers and analytics. Live from horizon.stellar.org.

 Stellar Pools API — oanor API marketplace

Stellar Pools API

Read live Stellar liquidity pools — the network's native automated market maker — straight from the public Horizon API, no key. Every Stellar pool is a constant-product market maker between two assets; this surfaces what asset and order-book readers miss: browse the pools with their two reserves, fee, share count and the number of trustlines (participants); read any single pool by its id; or find every pool that holds a given asset, against XLM or another token, to see exactly where a token has on-chain liquidity and at what depth. The automated-market-maker layer for Stellar wallets, anchors, swap UIs, liquidity providers and analytics. Live from the network; short cache only.

 Stellar (XLM) On-Chain API — oanor API marketplace

Stellar (XLM) On-Chain API

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.

 Sifchain API — oanor API marketplace

Sifchain API

Live on-chain data for Sifchain (chain id sifchain-1) — the Cosmos-SDK Layer-1 omni-chain decentralised exchange, whose native token is ROWAN — served directly from public LCD/REST nodes with multi-node failover. The status endpoint returns the latest block height and time, chain id, the staking bond denom and the current minting inflation rate. The validators endpoint lists the active bonded validator set ranked by stake, each with its moniker, operator address, self-plus-delegated ROWAN, commission rate and jailed flag. The supply endpoint returns the total ROWAN supply, the amount bonded in staking and the resulting bonded ratio. The governance endpoint returns the most recent on-chain proposals with their id, title, status and voting window. ROWAN uses an 18-decimal base denomination which is converted to whole ROWAN with exact big-integer scaling, and every figure is read live from the chain — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for staking dashboards, validator and delegator tooling, explorers, governance trackers and portfolio or analytics apps across the Cosmos and cross-chain DEX ecosystem. Live keyless upstream. 5 endpoints.
