Real-time on-chain data for Plasma (chain-id 9745) — the stablecoin-native EVM Layer-1 anchored to Bitcoin and purpose-built for high-volume, low-cost stablecoin (USD₮) payments. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native XPL balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Plasma JSON-RPC node — decoded from hex into plain decimals and human-readable XPL so you do not have to. Ideal for explorers, wallets, payment dashboards, gas estimators and analytics on the Plasma chain.

Live on-chain data from the Litecoin network (LTC), the long-running silver-to-Bitcoin's-gold proof-of-work UTXO chain with 2.5-minute blocks and Scrypt mining, via the public litecoinspace.org explorer. Like Bitcoin, Litecoin is UTXO-based. Resolve any address's confirmed LTC balance, the total it has ever received and sent, its transaction count and any unconfirmed mempool balance. Look up a transaction's fee, size, input and output counts, total output value and confirmation status. Read a block's height, hash, timestamp, transaction count, size and difficulty. Get the live chain state — the tip height, the recommended fee rates, the mempool size and fees, and the next difficulty adjustment. Live, no key, nothing stored. Distinct from the Bitcoin, Kaspa, XRP Ledger, Cardano, Hedera, Cosmos, Sui, NEAR, MultiversX, Starknet, Solana and EVM on-chain APIs and from price feeds — this is Litecoin's UTXO address state, transactions, blocks and fees. Perfect for wallets, explorers and payments apps.

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.

Live on-chain data from the XRP Ledger (XRPL), the decentralized blockchain behind XRP, served straight from public XRPL nodes by JSON-RPC — no key, nothing cached. The account endpoint returns any address's core state: its XRP balance, transaction sequence, the number of objects it owns, and its account flags and domain — the genesis-era account rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh holds tens of thousands of XRP. The balances endpoint returns the full wallet: the XRP balance plus every issued-currency trustline (token or stablecoin) the account holds, with the issuer, currency and amount, decoding hex currency codes to readable tickers. The transactions endpoint returns the account's most recent ledger activity — payments, DEX offers, trustline changes — each with its hash, type, amount, fee, result and time. The server endpoint returns the state of the ledger itself: the latest validated ledger index and age, the base and per-object XRP reserves, the current fee and the node software version — the network health a wallet or explorer needs. Everything is read live from the XRPL, nothing stored. This is the XRP Ledger on-chain layer for any wallet, explorer, exchange, payments or analytics app. Distinct from EVM and Solana on-chain APIs and from price feeds — this is XRPL account state, token balances, transactions and ledger health. 4 endpoints, no key on our side.

Live data for Bitcoin's Lightning Network — the instant-payment layer on top of Bitcoin — served straight from mempool.space's public API, no key, nothing cached. The stats endpoint returns the state of the whole network: how many nodes and payment channels exist, the total capacity locked in Bitcoin, the average and median channel capacity, the average fee rate, and the split between clearnet and Tor nodes — the network runs tens of thousands of channels holding thousands of BTC. The top endpoint is the node league table, ranked by liquidity (capacity) or by connectivity (channel count), with each node's alias, capacity and channel count — Bitfinex and Binance run some of the largest routing nodes. The search endpoint finds nodes by alias and returns their public key, capacity and channel count. This is the routing-and-liquidity layer for any Lightning wallet, node operator, payment or analytics app — who the big routing nodes are and how much capacity the network holds. Live from mempool.space, nothing stored. Distinct from on-chain Bitcoin and fee APIs — this is the Lightning Network layer. 4 endpoints.

Live on-chain data for Electroneum Smart Chain — an EVM Layer 1 built for mobile payments — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's ETN balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in ETN, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in ETN, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

Live on-chain data for Fuse Network — an EVM Layer 1 for payments and stablecoins — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, validator and timestamp. The address endpoint returns any account's FUSE balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in FUSE, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in FUSE, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

ISO 18245 Merchant Category Codes (MCC) as an API — the 981 four-digit codes that Visa, Mastercard and other card networks use to classify a merchant's line of business. Look up any code (e.g. 5812 → Eating places and Restaurants, 5411 → Grocery Stores/Supermarkets, 3000 → United Airlines), search by description (e.g. "hotel", "airline", "pharmacy"), filter by IRS-reportable status, or list them all. Each record carries the network/edited description, USDA and IRS descriptions and whether the category is IRS 1099-reportable. Ideal for payments, fintech, expense management, fraud analysis and transaction enrichment.
