Factomd

This is the API reference for the factomd process. The API is designed for outside application to process transactions and interact with the Factom federated servers. It’s listening port can be configured and runs on 8088 by default.
All these APIs use JSON-RPC, which is a remote procedure call protocol encoded in JSON. It is a very simple protocol (and very similar to XML-RPC), defining only a handful of data types and commands.
They can be invoked in your terminal as:
curl -X POST --data-binary '{"jsonrpc": "2.0", "id": 0, "method": "METHOD_HERE", "params": {"PARAM_1":"PARAM_DATA_1"}}' -H 'content-type:text/plain;' http://localhost:8088/v2
The output will also be JSON.
The right panel will contain the curl commands to be run in your terminal, as well as the JSON structures of the request and response. The JSON structs detail the required parameters for each call.

Retrieve administrative blocks for any given height.
The admin block contains data related to the identities within the factom system and the decisions the system makes as it builds the block chain. The ‘abentries’ (admin block entries) in the JSON response can be of various types, the most common is a directory block signature (DBSig). A majority of the federated servers sign every directory block, meaning every block after m5 will contain 5 DBSigs in each admin block.

This API call is used to find the status of a transaction, whether it be a factoid, reveal entry, or commit entry. When using this, you must specify the type of the transaction by giving the chainid field 1 of 3 values:
f for factoid transactions
c for entry credit transactions (commit entry/chain)
################################################################ for reveal entry/chain
Where # is the ChainID of the entry
The status types returned are as follows:
“Unknown” : Not found anywhere
“NotConfirmed” : Found on local node, but not in network (Holding Map)
“TransactionACK” : Found in network, but not written to the blockchain yet (ProcessList)
“DBlockConfirmed” : Found in Blockchain
You may also provide the full marshaled transaction, instead of a hash, and it will be hashed for you.
The responses vary based on the type:

Requesting an entry requires you to specify if the hash you provide is a commit or an entry hash. The chainid field is used to specify this. If you are searching for a commit, put c as the chainid field, otherwise, put the chainid that the entry belongs too.
For commit/reveal acks, the response has 2 sections, one for the commit, one for the reveal. If you provide the entryhash and chainid, both will be filled (if found). If you only provide the commit txid and c as the chainid, then only the commitdata is guaranteed to come back with data. The committxid and entryhash fields correspond to the commitdataand entrydata objects.
Why c? It is short for:000000000000000000000000000000000000000000000000000000000000000c
which is the chainid for all entry credit blocks. All commits are placed in the entry credit block (assuming they are valid and are properly paid for).

The hash field for a factoid transaction is equivalent to txid. To indicate the hash is a factoid transaction, put f in the chainid field and the txid in the hash field.
The response will look different than entry related ack calls.
Why f? It is short for:
000000000000000000000000000000000000000000000000000000000000000f
which is the chainid for all factoid blocks. All factoid transactions are placed in the factoid (assuming they are valid).

Send a Chain Commit Message to factomd to create a new Chain. The commit chain hex encoded string is documented here.
The commit-chain API takes a specifically formated message encoded in hex that includes signatures. If you have a factom-walletd instance running, you can construct this commit-chain API call with compose-chain which takes easier to construct arguments.
The compose-chain api call has two api calls in it’s response: commit-chain and reveal-chain. To successfully create a chain, the reveal-chain must be called after the commit-chain.
It is possible to be unable to send a commit, if the commit already exists (if you try to send it twice). This is a mechanism to prevent you from double spending. If you encounter this error, just skip to the reveal-chain. The error format can be found here: repeated-commit

Send an Entry Commit Message to factom to create a new Entry. The entry commit hex encoded string is documented here.

The current-minute API call returns:
leaderheight returns the current block height.
directoryblockheight returns the last saved height.
minute returns the current minute number for the open entry block.
currentblockstarttime returns the start time for the current block.
currentminutestarttime returns the start time for the current minute.
currenttime returns the current nodes understanding of current time.
directoryblockinseconds returns the number of seconds per block.
stalldetected returns if factomd thinks it has stalled.
faulttimeout returns the number of seconds before leader node is faulted for failing to provide a necessary message.
roundtimeout returns the number of seconds between rounds of an election during a fault.
dblock-by-height
Retrieves a directory block given only its height.

Every directory block has a KeyMR (Key Merkle Root), which can be used to retrieve it. The response will contain information that can be used to navigate through all transactions (entry and factoid) within that block. The header of the directory block will contain information regarding the previous directory block’s keyMR, directory block height, and the timestamp.

Submit a factoid transaction. The transaction hex encoded string is documented here.
The factoid-submit API takes a specifically formatted message encoded in hex that includes signatures. If you have a factom-walletd instance running, you can construct this factoid-submit API call with compose-transaction which takes easier to construct arguments.

Returns various heights that allows you to view the state of the blockchain. The heights returned provide a lot of information regarding the state of factomd, but not all are needed by most applications. The heights also indicate the most recent block, which could not be complete, and still being built. The heights mean as follows:
directoryblockheight : The current directory block height of the local factomd node.
leaderheight : The current block being worked on by the leaders in the network. This block is not yet complete, but all transactions submitted will go into this block (depending on network conditions, the transaction may be delayed into the next block)
entryblockheight : The height at which the factomd node has all the entry blocks. Directory blocks are obtained first, entry blocks could be lagging behind the directory block when syncing.
entryheight : The height at which the local factomd node has all the entries. If you added entries at a block height above this, they will not be able to be retrieved by the local factomd until it syncs further.
A fully synced node should show the same number for all, (except between minute 0 and 1, when leaderheight will be 1 block ahead.)

The multiple-ec-balances API is used to query the acknowledged and saved balances for a list of entry credit addresses.
currentheight is the current height that factomd was loading.
lastsavedheight is the height last saved to the database.
In balances it returns "ack", "saved" and "err".
ack is the balance after processing any in-flight transactions known to the Factom node responding to the API call
saved is the last saved to the database
err is just used to display any error that might have happened during the request. If it is "" that means there was no error.
If the syntax of the parameters is off e.g. missing a quote, a comma, or a square bracket, it will return: {“jsonrpc”:“2.0”,“id”:null,“error”:{“code”:-32600,“message”:“Invalid Request”}}
If the parameters are labeled incorrectly the call will return: “{“code”:-32602,“message”:“Invalid params”,“data”:“ERROR! Invalid params passed in, expected 'addresses’”}”
If factomd is not loaded up all the way to the last saved block it will return: {“currentheight”:0,“lastsavedheight”:0,“balances”:[{“ack”:0,“saved”:0,“err”:“Not fully booted”}]}
If the list of addresses contains an incorrectly formatted address the call will return: {“currentheight”:0,“lastsavedheight”:0,“balances”:[{“ack”:0,“saved”:0,“err”:“Error decoding address”}]}
If an address in the list is valid but has never been part of a transaction the call will return: “balances”:[{“ack”:0,“saved”:0,“err”:“Address has not had a transaction”}]“
Referring to the example request: This Example is for simulation, these addresses may not work or have the same value for mainnet or testnet.
