As a full Observable API, all interface calls return RxJS Observables, including the static `.create(...)`. In the same fashion and subscription-based methods return long-running Observables that update with the latest values.\n *\n * The API is well suited to real-time applications where the latest state is needed, unlocking the subscription-based features of Polkadot (and Substrate) clients. Some familiarity with RxJS is a requirement to use the API, however just understanding `.subscribe` and `.pipe` on Observables will unlock full-scale use thereof.\n *\n * @see [[ApiPromise]]\n *\n * ## Usage\n *\n * Making rpc calls -\n * <BR>\n *\n * ```javascript\n * import ApiRx from '@polkadot/api/rx';\n *\n * // initialize via Promise & static create\n * const api = await ApiRx.create().toPromise();\n *\n * // make a call to retrieve the current network head\n * api.rpc.chain.subscribeNewHeads().subscribe((header) => {\n * console.log(`Chain is at #${header.number}`);\n * });\n * ```\n * <BR>\n *\n * Subscribing to chain state -\n * <BR>\n *\n * ```javascript\n * import { combineLatest, pairwise, switchMap } from 'rxjs';\n * import { ApiRx, WsProvider } from '@polkadot/api';\n *\n *\n * // initialize a provider with a specific endpoint\n * const provider = new WsProvider('wss://example.com:9944')\n *\n * // initialize via isReady & new with specific provider\n * new ApiRx({ provider })\n * .isReady\n * .pipe(\n * switchMap((api) =>\n * combineLatest([\n * api.query.timestamp.blockPeriod(),\n * api.query.timestamp.now().pipe(pairwise())\n * ])\n * )\n * )\n * .subscribe(([blockPeriod, timestamp]) => {\n * const elapsed = timestamp[1].toNumber() - timestamp[0].toNumber();\n * console.log(`timestamp ${timestamp[1]} \\nelapsed ${elapsed} \\n(${blockPeriod}s target)`);\n * });\n * ```\n * <BR>\n *\n * Submitting a transaction -\n * <BR>\n *\n * ```javascript\n * import { first, switchMap } from 'rxjs';\n * import ApiRx from '@polkadot/api/rx';\n *\n * // import the test keyring (already has dev keys for Alice, Bob, Charlie, Eve & Ferdie)\n * import testingPairs from '@polkadot/keyring/testingPairs';\n * const keyring = testingPairs();\n *\n * // get api via Promise\n * const api = await ApiRx.create().toPromise();\n *\n * // retrieve nonce for the account\n * api.query.system\n * .account(keyring.alice.address)\n * .pipe(\n * first(),\n * // pipe nonce into transfer\n * switchMap(([nonce]) =>\n * api.tx.balances\n * // create transfer\n * .transferAllowDeath(keyring.bob.address, 12345)\n * // sign the transaction\n * .sign(keyring.alice, { nonce })\n * // send the transaction\n * .send()\n * )\n * )\n * // subscribe to overall result\n * .subscribe(({ status }) => {\n * if (status.isInBlock) {\n * console.log('Completed at block hash', status.asFinalized.toHex());\n * }\n * });\n * ```\n */\n class ApiRx extends _baseIndexJs.ApiBase {\n #isReadyRx;\n /**\n * @description Create an instance of the ApiRx class\n * @param options Options to create an instance.
