# General Info
## General API Information
* Some endpoints will require an API Key. Please refer to [this page](https://www.asterdex.com/)
* The base endpoint is: **https://fapi.asterdex.com**
* All endpoints return either a JSON object or array.
* Data is returned in **ascending** order. Oldest first, newest last.
* All time and timestamp related fields are in milliseconds.
* All data types adopt definition in JAVA.
### HTTP Return Codes
* HTTP `4XX` return codes are used for for malformed requests;
the issue is on the sender's side.
* HTTP `403` return code is used when the WAF Limit (Web Application Firewall) has been violated.
* HTTP `429` return code is used when breaking a request rate limit.
* HTTP `418` return code is used when an IP has been auto-banned for continuing to send requests after receiving `429` codes.
* HTTP `5XX` return codes are used for internal errors; the issue is on
Aster's side.
* HTTP `503` return code is used when the API successfully sent the message but not get a response within the timeout period.
It is important to **NOT** treat this as a failure operation; the execution status is
**UNKNOWN** and could have been a success.
### Error Codes and Messages
* Any endpoint can return an ERROR
> ***The error payload is as follows:***
```javascript
{
"code": -1121,
"msg": "Invalid symbol."
}
```
* Specific error codes and messages defined in [Error Codes](#error-codes).
### General Information on Endpoints
* For `GET` endpoints, parameters must be sent as a `query string`.
* For `POST`, `PUT`, and `DELETE` endpoints, the parameters may be sent as a
`query string` or in the `request body` with content type
`application/x-www-form-urlencoded`. You may mix parameters between both the
`query string` and `request body` if you wish to do so.
* Parameters may be sent in any order.
* If a parameter sent in both the `query string` and `request body`, the
`query string` parameter will be used.
## LIMITS
* The `/fapi/v1/exchangeInfo` `rateLimits` array contains objects related to the exchange's `RAW_REQUEST`, `REQUEST_WEIGHT`, and `ORDER` rate limits. These are further defined in the `ENUM definitions` section under `Rate limiters (rateLimitType)`.
* A `429` will be returned when either rate limit is violated.
<aside class="notice">
Aster Finance has the right to further tighten the rate limits on users with intent to attack.
</aside>
### IP Limits
* Every request will contain `X-MBX-USED-WEIGHT-(intervalNum)(intervalLetter)` in the response headers which has the current used weight for the IP for all request rate limiters defined.
* Each route has a `weight` which determines for the number of requests each endpoint counts for. Heavier endpoints and endpoints that do operations on multiple symbols will have a heavier `weight`.
* When a 429 is received, it's your obligation as an API to back off and not spam the API.
* **Repeatedly violating rate limits and/or failing to back off after receiving 429s will result in an automated IP ban (HTTP status 418).**
* IP bans are tracked and **scale in duration** for repeat offenders, **from 2 minutes to 3 days**.
* **The limits on the API are based on the IPs, not the API keys.**
<aside class="notice">
It is strongly recommended to use websocket stream for getting data as much as possible, which can not only ensure the timeliness of the message, but also reduce the access restriction pressure caused by the request.
</aside>
### Order Rate Limits
* Every order response will contain a `X-MBX-ORDER-COUNT-(intervalNum)(intervalLetter)` header which has the current order count for the account for all order rate limiters defined.
* Rejected/unsuccessful orders are not guaranteed to have `X-MBX-ORDER-COUNT-**` headers in the response.
* **The order rate limit is counted against each account**.
## Endpoint Security Type
* Each endpoint has a security type that determines the how you will
interact with it.
* API-keys are passed into the Rest API via the `X-MBX-APIKEY`
header.
* API-keys and secret-keys **are case sensitive**.
* API-keys can be configured to only access certain types of secure endpoints.
For example, one API-key could be used for TRADE only, while another API-key
can access everything except for TRADE routes.
* By default, API-keys can access all secure routes.
Security Type | Description
------------ | ------------
NONE | Endpoint can be accessed freely.
TRADE | Endpoint requires sending a valid API-Key and signature.
USER_DATA | Endpoint requires sending a valid API-Key and signature.
USER_STREAM | Endpoint requires sending a valid API-Key.
MARKET_DATA | Endpoint requires sending a valid API-Key.
* `TRADE` and `USER_DATA` endpoints are `SIGNED` endpoints.
## SIGNED (TRADE and USER_DATA) Endpoint Security
* `SIGNED` endpoints require an additional parameter, `signature`, to be
sent in the `query string` or `request body`.
* Endpoints use `HMAC SHA256` signatures. The `HMAC SHA256 signature` is a keyed `HMAC SHA256` operation.
Use your `secretKey` as the key and `totalParams` as the value for the HMAC operation.
* The `signature` is **not case sensitive**.
* Please make sure the `signature` is the end part of your `query string` or `request body`.
* `totalParams` is defined as the `query string` concatenated with the
`request body`.
### Timing Security
* A `SIGNED` endpoint also requires a parameter, `timestamp`, to be sent which
should be the millisecond timestamp of when the request was created and sent.
* An additional parameter, `recvWindow`, may be sent to specify the number of
milliseconds after `timestamp` the request is valid for. If `recvWindow`
is not sent, **it defaults to 5000**.
> The logic is as follows:
```javascript
if (timestamp < (serverTime + 1000) && (serverTime - timestamp) <= recvWindow){
// process request
}
else {
// reject request
}
```
**Serious trading is about timing.** Networks can be unstable and unreliable,
which can lead to requests taking varying amounts of time to reach the
servers. With `recvWindow`, you can specify that the request must be
processed within a certain number of milliseconds or be rejected by the
server.
<aside class="notice">
It is recommended to use a small recvWindow of 5000 or less!
</aside>

## Filters
Filters define trading rules on a symbol or an exchange.
### Symbol filters
#### PRICE_FILTER
> **/exchangeInfo format:**
```javascript
{
"filterType": "PRICE_FILTER",
"minPrice": "0.00000100",
"maxPrice": "100000.00000000",
"tickSize": "0.00000100"
}
```
The `PRICE_FILTER` defines the `price` rules for a symbol. There are 3 parts:
* `minPrice` defines the minimum `price`/`stopPrice` allowed; disabled on `minPrice` == 0.
* `maxPrice` defines the maximum `price`/`stopPrice` allowed; disabled on `maxPrice` == 0.
* `tickSize` defines the intervals that a `price`/`stopPrice` can be increased/decreased by; disabled on `tickSize` == 0.
Any of the above variables can be set to 0, which disables that rule in the `price filter`. In order to pass the `price filter`, the following must be true for `price`/`stopPrice` of the enabled rules:
* `price` >= `minPrice`
* `price` <= `maxPrice`
* (`price`-`minPrice`) % `tickSize` == 0
#### LOT_SIZE
> **/exchangeInfo format:**
```javascript
{
"filterType": "LOT_SIZE",
"minQty": "0.00100000",
"maxQty": "100000.00000000",
"stepSize": "0.00100000"
}
```
The `LOT_SIZE` filter defines the `quantity` (aka "lots" in auction terms) rules for a symbol. There are 3 parts:
* `minQty` defines the minimum `quantity` allowed.
* `maxQty` defines the maximum `quantity` allowed.
* `stepSize` defines the intervals that a `quantity` can be increased/decreased by.
In order to pass the `lot size`, the following must be true for `quantity`:
* `quantity` >= `minQty`
* `quantity` <= `maxQty`
* (`quantity`-`minQty`) % `stepSize` == 0
#### MARKET_LOT_SIZE
> **/exchangeInfo format:**
```javascript
{
"filterType": "MARKET_LOT_SIZE",
"minQty": "0.00100000",
"maxQty": "100000.00000000",
"stepSize": "0.00100000"
}
```
The `MARKET_LOT_SIZE` filter defines the `quantity` (aka "lots" in auction terms) rules for `MARKET` orders on a symbol. There are 3 parts:
* `minQty` defines the minimum `quantity` allowed.
* `maxQty` defines the maximum `quantity` allowed.
* `stepSize` defines the intervals that a `quantity` can be increased/decreased by.
In order to pass the `market lot size`, the following must be true for `quantity`:
* `quantity` >= `minQty`
* `quantity` <= `maxQty`
* (`quantity`-`minQty`) % `stepSize` == 0
#### MAX_NUM_ORDERS
> **/exchangeInfo format:**
```javascript
{
"filterType": "MAX_NUM_ORDERS",
"limit": 200
}
```
The `MAX_NUM_ORDERS` filter defines the maximum number of orders an account is allowed to have open on a symbol.
Note that both "algo" orders and normal orders are counted for this filter.
#### MAX_NUM_ALGO_ORDERS
> **/exchangeInfo format:**
```javascript
{
"filterType": "MAX_NUM_ALGO_ORDERS",
"limit": 100
}
```
The `MAX_NUM_ALGO_ORDERS ` filter defines the maximum number of all kinds of algo orders an account is allowed to have open on a symbol.
The algo orders include `STOP`, `STOP_MARKET`, `TAKE_PROFIT`, `TAKE_PROFIT_MARKET`, and `TRAILING_STOP_MARKET` orders.
#### PERCENT_PRICE
> **/exchangeInfo format:**
```javascript
{
"filterType": "PERCENT_PRICE",
"multiplierUp": "1.1500",
"multiplierDown": "0.8500",
"multiplierDecimal": 4
}
```
The `PERCENT_PRICE` filter defines valid range for a price based on the mark price.
In order to pass the `percent price`, the following must be true for `price`:
* BUY: `price` <= `markPrice` * `multiplierUp`
* SELL: `price` >= `markPrice` * `multiplierDown`
#### MIN_NOTIONAL
> **/exchangeInfo format:**
```javascript
{
"filterType": "MIN_NOTIONAL",
"notional": "1"
}
```
The `MIN_NOTIONAL` filter defines the minimum notional value allowed for an order on a symbol.
An order's notional value is the `price` * `quantity`.
Since `MARKET` orders have no price, the mark price is used.

# Websocket Market Streams
* The baseurl for websocket is **wss://fstream.asterdex.com**
* Streams can be access either in a single raw stream or a combined stream
* Raw streams are accessed at **/ws/\<streamName\>**
* Combined streams are accessed at **/stream?streams=\<streamName1\>/\<streamName2\>/\<streamName3\>**
* Combined stream events are wrapped as follows: **{"stream":"\<streamName\>","data":\<rawPayload\>}**
* All symbols for streams are **lowercase**
* A single connection is only valid for 24 hours; expect to be disconnected at the 24 hour mark
* The websocket server will send a `ping frame` every 5 minutes. If the websocket server does not receive a `pong frame` back from the connection within a 15 minute period, the connection will be disconnected. Unsolicited `pong frames` are allowed.
* WebSocket connections have a limit of 10 incoming messages per second.
* A connection that goes beyond the limit will be disconnected; IPs that are repeatedly disconnected may be banned.
* A single connection can listen to a maximum of **200** streams.
* Considering the possible data latency from RESTful endpoints during an extremely volatile market, it is highly recommended to get the order status, position, etc from the Websocket user data stream.
## Live Subscribing/Unsubscribing to streams
* The following data can be sent through the websocket instance in order to subscribe/unsubscribe from streams. Examples can be seen below.
* The `id` used in the JSON payloads is an unsigned INT used as an identifier to uniquely identify the messages going back and forth.
### Subscribe to a stream

## How to manage a local order book correctly
1. Open a stream to **wss://fstream.asterdex.com/stream?streams=btcusdt@depth**.
2. Buffer the events you receive from the stream. For same price, latest received update covers the previous one.
3. Get a depth snapshot from **https://fapi.asterdex.com/fapi/v1/depth?symbol=BTCUSDT&limit=1000** .
4. Drop any event where `u` is < `lastUpdateId` in the snapshot.
5. The first processed event should have `U` <= `lastUpdateId` **AND** `u` >= `lastUpdateId`
6. While listening to the stream, each new event's `pu` should be equal to the previous event's `u`, otherwise initialize the process from step 3.
7. The data in each event is the **absolute** quantity for a price level.
8. If the quantity is 0, **remove** the price level.
9. Receiving an event that removes a price level that is not in your local order book can happen and is normal.

* Example usage:
Call this endpoint at 30s intervals with an countdownTime of 120000 (120s).
If this endpoint is not called within 120 seconds, all your orders of the specified symbol will be automatically canceled.
If this endpoint is called with an countdownTime of 0, the countdown timer will be stopped.
* The system will check all countdowns **approximately every 10 milliseconds**, so please note that sufficient redundancy should be considered when using this function. We do not recommend setting the countdown time to be too precise or too small.

# User Data Streams
* The base API endpoint is: **https://fapi.asterdex.com**
* A User Data Stream `listenKey` is valid for 60 minutes after creation.
* Doing a `PUT` on a `listenKey` will extend its validity for 60 minutes.
* Doing a `DELETE` on a `listenKey` will close the stream and invalidate the `listenKey`.
* Doing a `POST` on an account with an active `listenKey` will return the currently active `listenKey` and extend its validity for 60 minutes.
* The baseurl for websocket is **wss://fstream.asterdex.com**
* User Data Streams are accessed at **/ws/\<listenKey\>**
* User data stream payloads are **not guaranteed** to be in order during heavy periods; **make sure to order your updates using E**
* A single connection to **fstream.asterdex.com** is only valid for 24 hours; expect to be disconnected at the 24 hour mark
