Cronos API

healthy 4,413 Subscribers

Real-time on-chain data for Cronos (chain-id 25) — the EVM-compatible Layer-1 (Cosmos SDK / Ethermint) backed by Crypto.com, using CRO as its native coin. 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 CRO balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Cronos JSON-RPC node — decoded from hex into plain decimals and human-readable CRO so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on Cronos.

Crypto.com Exchange API

Live spot market data from the Crypto.com Exchange, one of the largest global retail crypto venues and the heart of the CRO ecosystem, served straight from its public API with no key and nothing cached. The ticker endpoint returns a market's last price, best bid and ask, the spread, 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 gives you the most-traded pairs on the venue. The instruments endpoint lists the tradable spot pairs with their price and quantity tick sizes and decimal precision. The book endpoint returns live order-book depth — every bid and ask level with price, amount and order count, plus the best bid/ask and spread. Everything is read live from Crypto.com on each request, nothing stored; perpetual contracts are excluded so you get clean spot data. 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 perpetuals or candles use a derivatives or OHLC API.

Carbon API

Live on-chain data for Carbon (chain id carbon-1) — the Switcheo-built Cosmos-SDK Layer-1 for decentralised derivatives and spot trading, whose native token is SWTH — 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 SWTH, commission rate and jailed flag. The supply endpoint returns the total SWTH 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. SWTH uses an 8-decimal base denomination which is converted to whole SWTH 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 DeFi ecosystem. Live keyless upstream. 5 endpoints.

Fetch.ai API

Live on-chain data for Fetch.ai (chain id fetchhub-4) — the Cosmos-SDK Layer-1 behind the Artificial Superintelligence Alliance, whose native token is FET — 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 FET, commission rate and jailed flag. The supply endpoint returns the total FET 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. FET uses an 18-decimal base denomination (afet) which is converted to whole FET 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 AI-blockchain ecosystem. Live keyless upstream. 5 endpoints.

Oraichain API

Live on-chain data for Oraichain — the AI-oracle Layer-1 built on the Cosmos SDK, whose native token is ORAI — 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 ORAI tokens, commission rate and jailed flag. The supply endpoint returns the total ORAI 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. Token amounts are converted from base micro-ORAI (6 decimals) into whole ORAI, and all figures are read live from the chain — nothing is bundled or modelled — with a short server-side cache and 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 covering the Cosmos and AI-blockchain ecosystem. Live keyless upstream. 5 endpoints.
