# API # API
Serve on `http://localhost:2024` In order to allow for quick client development, with the security
of the light-client and ease of use the cli (embedding go-wire and
go-crypto), we will provide a REST API, which can run on localhost
as part of `basecli`, securely managing your keys, signing transactions,
and validating queries. It will be exposed for a locally deployed
application to make use of (eg. electron app, web server...)
Don't allow cors By default we will serve on `http://localhost:2024`. CORS will be disabled by default. Potentially we can add a flag to enable it for one domain.
## Create Tx ## MVP
`POST /tx` The MVP will allow us to move around money. This involves the
following functions:
Input: signed tx as json, just like --prepare... ## Construct an unsigned tx
Goes to the node, and returns result:
``` `POST /build/send`

Example tx: Output (a json encoding of basecoin.Tx):
wrappers = combine(feeWrap, nonceWrap, chainWrap, sigWrap) `basecli tx send --to=role:62616E6B32 --from=sigs:91C959ADE03D8973E8F2FBA9FD2EED327DCE2B0A --amount=900000mycoin --sequence=1 --multi --prepare=- --no-sign`

Matt's proposal: ## Sign a Tx
`POST /build/send` Once you construct a proper json-encoded `basecoin.Tx`, you can sign it once, or (if you constructed it with `multi=true`), multiple times.
`POST /sign`
Input: Input:
``` ```

## Send Tx to the Blockchain
## Query: This will encode the transaction as binary and post it to the tendermint node, waiting until it is committed to the blockchain.
(TODO: make this async? return when recevied, notify when committed?)

## Other stuff for MVP
## Other stuff You must run `basecli init` int he cli to set things up.
`init` / `serve` on cli When you run `basecli serve`, it will start the local rest api server, with the above endpoints.
keys management under `/keys`: Also, support keys endpoints from go-crypto as they currently are and mount them under `/keys`.
List, get, create (delete + update)? ## Future Stuff
proxy mounted as well under `/tendermint` proxy mounted as well under `/tendermint`
