Public Rest API for Namebase

General API Information

The root API URL is https://www.namebase.io
Parameters for GET requests must be sent as a query string.
All other request methods require parameters in the request body as Content-Type: application/json
Parameter order does not matter.
All timestamps are in milliseconds.
API errors take the following form:

{
  "code": "NAMEBASE_API_ERROR_CODE",
  "message": "Error message appears here."
}

Rate limiting

If your account repeatedly gets rate limited, then you are using the API improperly and must back off. Failure to do so will cause your account to lose API access. Namebase retains the right to ban your account with no notice if you are abusing the API.

The rate limits are set generously and are not meant to prohibit any amount of normal usage. In the future, we will standardize our rate limits and provide more explicit feedback about how many remaining requests you can send each minute.

Timing security

Some endpoints require you to send a timestamp of when you created the request.
You can optionally specify a receiveWindow which determines when your timestamped request expires.
The receiveWindow defaults to 5 seconds (so, 5000)
If your timestamp is ahead of the server time by too much, you will receive an error complaining about sending a timestamp from the future.
You can query the exchange info endpoint to synchronize your computer's clock with the exchange's.

Public Namebase API

Terminology

For a symbol like HNSBTC, HNS is the "base" asset and BTC is the "quote" asset
All prices are in the units of quote asset per 1 unit of the base asset
All quantities are in the units of the base asset, and all quote quantities are in the units of the quote asset
Similarly, volumes are in the units of the base asset, and quote volumes are in the units of the quote asset

ENUM definitions

Order types

LMT (limit)
MKT (market)

Order status

NEW (on the book, no trades yet)
PARTIALLY_FILLED (on the book, some trades have occurred)
FILLED (automatically taken off the book, order fully satisfied)
CLOSED (automatically taken off the book, order partially satisfied)
CANCELED (the trader took the order off the book, order partially satisfied)

When a limit buy order is placed, due to complexities with rounding numbers, it may be the case that your order lacks sufficient quote to be fully satisfied. In this scenario, your order will automatically be removed from the book (the CLOSED state) and you will be refunded the dusty quote amount that remained. In the case of BTC, this dust amount is often just a few satoshis. This is rare and requires no action on your part.

When a market order is placed, there may be insufficient liquidity to fully satisfy the order. Alternatively, there may be price slippage and your account may lack sufficient funds to fully satisfy the order. In either case, the order is automtically removed from the book and placed in the CLOSED state.

Lastly, if you place two orders on opposite sites and accidentally trade with yourself, then your more recent order, the taker order, will be automatically removed from the book and placed in the CLOSED state. Your older, original order will remain on the book. For your own protection (to save you trading fees), Namebase's matching engine will not match two orders from the same user.
