Stellar (XLM) On-Chain API

healthy 4,271 Subscribers

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.

Lighting Calculator API

Lighting design maths as an API, computed locally and deterministically. The room endpoint works out how many lumens a room needs from its area and a target illuminance — given directly in lux or chosen from a room-type preset (living, kitchen, office, workshop and more) — and, optionally, how many fixtures at a given lumen output and how many watts at a given lamp type. The lux endpoint converts between lux, footcandles and lumens over an area, so you can find the illuminance from a light output and a room size or vice versa. The efficacy endpoint relates lumens, watts and luminous efficacy (lumens per watt): give any two — or a lamp-type preset such as incandescent, halogen, CFL or LED — and it computes the third. Everything is computed locally and deterministically, so it is instant and private. It is a lumen-method estimate: target levels are typical guidance (EN 12464 / IES) and a full design would add room and utilisation factors. Ideal for lighting and electrical tools, interior-design and home apps, retrofit and energy-saving calculators, and smart-home planning. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is illumination maths; for Ohm's-law electrical quantities use an electronics API.

DigiFinex Exchange API

Live spot market data from DigiFinex, a global crypto exchange, served straight from its public v3 API with no key and nothing cached. The ticker endpoint returns a market's last price, best bid and ask, 24-hour high and low, 24-hour change and base and quote volume. The tickers endpoint returns every spot market for a quote currency ranked by 24-hour quote volume, so one call surfaces the most-traded pairs on the venue. The markets endpoint lists the tradable pairs with their price and volume precision and minimum order size. The book endpoint returns live order-book depth — every bid and ask level with price and amount, plus the best bid/ask and the spread. Everything is read live from DigiFinex on each request, nothing stored. A distinct global venue, separate from the other exchange feeds on the marketplace. Ideal for trading bots, price tickers, arbitrage scanners, portfolio trackers and market dashboards. Live, no key. 4 spot endpoints. For candles or perpetuals use an OHLC or derivatives API.

AscendEX Exchange API

Live spot market data from AscendEX (formerly BitMax), a global crypto exchange, served straight from its public API with no key and nothing cached. The ticker endpoint returns a market's last price, open, 24-hour high and low, 24-hour change, best bid and ask and volume. The tickers endpoint returns every spot market for a quote currency ranked by 24-hour volume, so one call surfaces the most-traded pairs on the venue. The markets endpoint lists the tradable pairs with their tick and lot size and minimum and maximum notional. The book endpoint returns live order-book depth — every bid and ask level with price and amount, plus the best bid/ask and the spread. Everything is read live from AscendEX on each request, nothing stored. A distinct global venue, separate from the other exchange feeds on the marketplace. Markets are written BASE/QUOTE; BTC_USDT is also accepted. Ideal for trading bots, price tickers, arbitrage scanners, portfolio trackers and market dashboards. Live, no key. 4 spot endpoints. For candles or perpetuals use an OHLC or derivatives API.

XT Exchange API

Live spot market data from XT.com, a global crypto exchange, served straight from its public v4 API with no key and nothing cached. The ticker endpoint returns a market's last price, open, 24-hour high and low, 24-hour change and base and quote volume. The tickers endpoint returns every spot market for a quote currency ranked by 24-hour quote volume, so one call surfaces the most-traded pairs on the venue. The markets endpoint lists the tradable pairs with their price and quantity precision and trading state. The book endpoint returns live order-book depth — every bid and ask level with price and amount, plus the best bid/ask and the spread. Everything is read live from XT on each request, nothing stored. A distinct global venue, separate from the other exchange feeds on the marketplace. Ideal for trading bots, price tickers, arbitrage scanners, portfolio trackers and market dashboards. Live, no key. 4 spot endpoints. For candles or perpetuals use an OHLC or derivatives API.
