Send your first request: ```python import requests url = "https://go.getblock.io//" headers = { "Content-Type": "application/json" } payload = { "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": "getblock.io" } response = requests.post(url, headers=headers, json=payload) print(response.json()) ``` ### Key Features of GetBlock GetBlock is offering one of the most comprehensive APIs toolkits in the segment supporting hundreds of dApps with fast and reliable connection to blockchain nodes. #### 100+ blockchains in store * Seamless connection to full and archive nodes * Shared and dedicated nodes: Tailored for your dApp’s needs. * Programmable and non-programmable blockchains * L1 and L2 protocols * EVM and non-EVM networks See full list: \ \ All mainstream RPC interfaces * WebSockets * JSON RPC * GraphQL * REST API * And more Add them in Lego-like manner: #### Industry-leading suite of add-ons and ready-made APIs * DAS API * Firehose * Blockbook * Yellowstone Geyser Need more? Don’t hesitate to contact sales: ## Examples for Console REST API Requests #### cURL Most \*nix-based systems come with cURL pre-installed. cURL is a command-line tool and library for transferring data with URLs. To check if cURL is installed, run the following command: ```json curl -h ``` Example of requesting the latest block number using the GetBlock API and cURL: ```json curl --location --request POST 'https://go.getblock.io//' \ --header 'Content-Type: application/json' \ --data-raw '{ "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": "getblock.io" }' ``` #### Python To run Python examples, ensure Python is installed along with the requests package. You can install the package using the following command: ```json python -m pip install requests ``` Example: ```python import requests url = "https://go.getblock.io//" headers = { "Content-Type": "application/json" } payload = { "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": "getblock.io" } response = requests.post(url, headers=headers, json=payload) print(response.json()) ``` #### JavaScript For JavaScript examples, you'll need Node.js version 18 or later. Follow the official documentation to install the latest stable version globally. Verify your installation by running: ``` node -v ``` #### Ruby To execute Ruby examples, install Ruby on your machine. Refer to the official installation guide for details. Confirm installation by running: ``` ruby -v ``` ## Supported networks We provide APIs for a wide range of networks, including: [Aptos (APT)](https://getblock.io/docs/apt/json-rpc/apt_v1_estimate_gas_price/) [Arbitrum (ARB)](https://getblock.io/docs/arb/json-rpc/arbitrum_eth_accounts/) [Avalanche (AVAX)](https://getblock.io/docs/avax/json-rpc/avax_eth_accounts/) [Bitcoin Cash (BCH)](https://getblock.io/docs/bch/json-rpc/bch_combinepsbt/) [BNB Smart Chain (BSC)](https://getblock.io/docs/bsc/json-rpc/bsc_debug_tracecall/) [Bitcoin-SV (BSV)](https://getblock.io/docs/bsv/json-rpc/bsv_analyzepsbt/) [Bitcoin (BTC)](https://getblock.io/docs/btc/json-rpc/btc_analyzepsbt/) [Bitcoin Gold (BTG)](https://getblock.io/docs/btg/json-rpc/btg_analyzepsbt/) [Cronos (CRO)](https://getblock.io/docs/cro/json-rpc/cro_eth_accounts/) [Dash (DASH)](https://getblock.io/docs/dash/json-rpc/dash_combinerawtransaction/) [DigiByte (DGB)](https://getblock.io/docs/dgb/json-rpc/dgb_analyzepsbt/) [Dogeсoin (DOGE)](https://getblock.io/docs/doge/json-rpc/doge_createrawtransaction/) [Polkadot (DOT)](https://getblock.io/docs/dot/json-rpc/dot_chain_getblock/) [Ethereum Classic (ETC)](https://getblock.io/docs/etc/json-rpc/etc_eth_accounts/) [Ethereum (ETH)](https://getblock.io/docs/eth/json-rpc/eth_eth_accounts/) [Fantom (FTM)](https://getblock.io/docs/ftm/json-rpc/ftm_dag_getevent/) [Fuse.io (FUSE)](https://getblock.io/docs/fuse/json-rpc/fuse_eth_accounts/) [Moonbeam (GLMR)](https://getblock.io/docs/glmr/json-rpc/glmr_eth_accounts/) [Gnosis Chain (GNO)](https://getblock.io/docs/gno/json-rpc/gno_eth_accounts/) [Huobi ECO Chain (HECO)](https://getblock.io/docs/heco/json-rpc/heco_eth_accounts/) [KuCoin Community Chain (KCC)](https://getblock.io/docs/kcc/json-rpc/kcc_eth_accounts/) [Kusama (KSM)](https://getblock.io/docs/ksm/json-rpc/ksm_chain_getblock/) [Polygon (MATIC)](https://getblock.io/docs/matic/json-rpc/matic_eth_accounts/) [Moonriver (MOVR)](https://getblock.io/docs/movr/json-rpc/movr_chain_getblock/) [Near Protocol (NEAR)](https://getblock.io/docs/near/json-rpc/near_block/) [Harmony (ONE)](https://getblock.io/docs/one/json-rpc/one_eth_accounts/) [Ontology (ONT)](https://getblock.io/docs/ont/json-rpc/ont_getbalance/) [Optimism (OP)](https://getblock.io/docs/op/json-rpc/optimism_eth_accounts/) [Rootstock (RSK)](https://getblock.io/docs/rsk/json-rpc/rsk_eth_accounts/) [Solana (SOL)](https://getblock.io/docs/sol/json-rpc/sol_getaccountinfo/) [Theta (THETA)](https://getblock.io/docs/theta/json-rpc/theta_theta.broadcastrawtransaction/) [TON (TON)](https://getblock.io/docs/ton/json-rpc/ton_detectaddress/) [Tron (TRX)](https://getblock.io/docs/trx/json-rpc/trx_eth_blocknumber/) [NEM (XEM)](https://getblock.io/docs/xem/rest/xem_account_get_forwarded_from-public-key/) [Monero (XMR)](https://getblock.io/docs/xmr/json-rpc/get_alternate_chains/) [ZCash (ZEC)](https://getblock.io/docs/zec/json-rpc/zec_createrawtransaction/) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
