In addition to the [standard API](#Methods), an [extension API](#WSExtMethods)
has been developed that is exclusive to clients using Websockets. In its current
state, this API attempts to cover features found missing in the standard API
during the development of btcwallet.
While the [standard API](#Methods) is stable, the
[Websocket extension API](#WSExtMethods) should be considered a work in
progress, incomplete, and susceptible to changes (both additions and removals).

| Parameters | 1. checklevel (numeric, optional, default=3) - how in-depth the verification is (0=least amount of checks, higher levels are clamped to the highest supported level)<br/>2. numblocks (numeric, optional, default=288) - the number of blocks starting from the end of the chain to verify |
| Description | Verifies the block chain database.<br/>The actual checks performed by the `checklevel` parameter is implementation specific. For lbcd this is:<br/>`checklevel=0` - Look up each block and ensure it can be loaded from the database.<br/>`checklevel=1` - Perform basic context-free sanity checks on each block. |
| Notes | <fontcolor="orange">lbcd currently only supports `checklevel` 0 and 1, but the default is still 3 for compatibility. Per the information in the Parameters section above, higher levels are automatically clamped to the highest supported level, so this means the default is effectively 1 for lbcd.</font> |
The following is an overview of the RPC methods which are implemented by lbcd, but not the original bitcoind client. Click the method name for further details such as parameter and return information.
| Description | Dynamically changes the debug logging level.<br/>The levelspec can either a debug level or of the form `<subsystem>=<level>,<subsystem2>=<level2>,...`<br/>The valid debug levels are `trace`, `debug`, `info`, `warn`, `error`, and `critical`.<br/>The valid subsystems are `AMGR`, `ADXR`, `BCDB`, `BMGR`, `lbcd`, `CHAN`, `DISC`, `PEER`, `RPCS`, `SCRP`, `SRVR`, and `TXMP`.<br/>Additionally, the special keyword `show` can be used to get a list of the available subsystems. |
| Description | Get block height and hash of best block in the main chain. |
| Returns | `{ (json object)`<br/> `"hash": "data", (string) the hex-encoded bytes of the best block hash`<br/> `"height": n (numeric) the block height of the best block`<br/>`}` |
| Parameters | 1. address (string, required) - bitcoin address <br/> 2. verbose (int, optional, default=true) - specifies the transaction is returned as a JSON object instead of hex-encoded string <br/>3. skip (int, optional, default=0) - the number of leading transactions to leave out of the final response <br/> 4. count (int, optional, default=100) - the maximum number of transactions to return <br/> 5. vinextra (int, optional, default=0) - Specify that extra data from previous output will be returned in vin <br/> 6. reverse (boolean, optional, default=false) - Specifies that the transactions should be returned in reverse chronological order |
| Description | Returns raw data for transactions involving the passed address. Returned transactions are pulled from both the database, and transactions currently in the mempool. Transactions pulled from the mempool will have the `"confirmations"` field set to 0. Usage of this RPC requires the optional `--addrindex` flag to be activated, otherwise all responses will simply return with an error stating the address index has not yet been built up. Similarly, until the address index has caught up with the current best height, all requests will return an error response in order to avoid serving stale data. |
| Returns (verbose=0) | `[ (json array of strings)`<br/> `"serializedtx", ... hex-encoded bytes of the serialized transaction`<br/>`]` |
| Returns (verbose=1) | `[ (array of json objects)`<br/> `{ (json object)`<br/> `"hex": "data", (string) hex-encoded transaction`<br/> `"txid": "hash", (string) the hash of the transaction`<br/> `"version": n, (numeric) the transaction version`<br/> `"locktime": n, (numeric) the transaction lock time`<br/> `"vin": [ (array of json objects) the transaction inputs as json objects`<br/> <fontcolor="orange">For coinbase transactions:</font><br/> `{ (json object)`<br/> `"coinbase": "data", (string) the hex-encoded bytes of the signature script`<br/> `"txinwitness": “data", (string) the witness stack for the input`<br/> `"sequence": n, (numeric) the script sequence number`<br/> `}`<br/> <fontcolor="orange">For non-coinbase transactions:</font><br/> `{ (json object)`<br/> `"txid": "hash", (string) the hash of the origin transaction`<br/> `"vout": n, (numeric) the index of the output being redeemed from the origin transaction`<br/> `"scriptSig": { (json object) the signature script used to redeem the origin transaction`<br/> `"asm": "asm", (string) disassembly of the script`<br/> `"hex": "data", (string) hex-encoded bytes of the script`<br/> `}`<br/> `"prevOut": { (json object) Data from the origin transaction output with index vout.`<br/> `"addresses": ["value",...], (array of string) previous output addresses`<br/> `"value": n.nnn, (numeric) previous output value`<br/> `}`<br/> `"txinwitness": “data", (string) the witness stack for the input`<br/> `"sequence": n, (numeric) the script sequence number`<br/> `}, ...`<br/> `]`<br/> `"vout": [ (array of json objects) the transaction outputs as json objects`<br/> `{ (json object)`<br/> `"value": n, (numeric) the value in BTC`<br/> `"n": n, (numeric) the index of this transaction output`<br/> `"scriptPubKey": { (json object) the public key script used to pay coins`<br/> `"asm": "asm", (string) disassembly of the script`<br/> `"hex": "data", (string) hex-encoded bytes of the script`<br/> `"reqSigs": n, (numeric) the number of required signatures`<br/> `"type": "scripttype" (string) the type of the script (e.g. 'pubkeyhash')`<br/> `"addresses": [ (json array of string) the bitcoin addresses associated with this output`<br/> `"address", (string) the bitcoin address`<br/> `...`<br/> `]`<br/> `}`<br/> `}, ...`<br/> `]`<br/> `"blockhash":"hash" Hash of the block the transaction is part of.`<br/> `"confirmations":n, Number of numeric confirmations of block.`<br/> `"time":t, Transaction time in seconds since the epoch.` <br/> `"blocktime":t, Block time in seconds since the epoch.`<br/>`},...`<br/>`]` |
| Parameters | 1. command (string, required) - `connect` to add a peer (defaults to temporary), `remove` to remove a persistent peer, or `disconnect` to remove all matching non-persistent peers <br/> 2. peer (string, required) - ip address and port, or ID of the peer to operate on<br/> 3. connection type (string, optional) - `perm` indicates the peer should be added as a permanent peer, `temp` indicates a connection should only be attempted once. |
| Description | Attempts to add or remove a peer. |
| Parameters | 1. numblocks (int, required) - The number of blocks to generate |

Additionally, if no EndBlock is provided, the client is automatically registered for transaction notifications for all rescanned addresses and the final UTXO set. Rescan results are sent as recvtx and redeemingtx notifications. This call returns once the rescan completes. |
| Notifications | [txaccepted](#txaccepted) or [txacceptedverbose](#txacceptedverbose) |

lbcd uses standard JSON-RPC notifications to notify clients of changes, rather than requiring clients to poll lbcd for updates. JSON-RPC notifications are a subset of requests, but do not contain an ID. The notification type is categorized by the `method` field and additional details are sent as a JSON array in the `params` field.
