K-Sortable Globally Unique IDs (ksuid)

Universally Unique Lexicographically Sortable Identifier (ulid)

curl -X GET 'https://api.onetimecode.net/ulid'

UUIDs

# get an UUID
curl -X GET 'https://api.onetimecode.net/uuid'
{"result":"7cc1e97d-6bed-4d63-be64-d0c74dc0c587"}

Shortcuts for numbers

Roll the dice

The /dice endpoint is an alias for /number?min=1&max=6.

curl -X GET 'https://api.onetimecode.net/dice'
{"result":"5"}

Toss a coin

The /coin endpoint is an alias for number?min=0&max=1. It returns either 0 or 1. The /coin endpoint is the only endpoint that returns an additional attribute side whereas 0 = head and 1 = tails.

curl -X GET 'https://api.onetimecode.net/coin'
{"result":"1", "side":"tails"}

Response

The API returns a JSON object with the key result and a string value.

{
  "result": "648197"
}

For the /coin endpoint:

{
  "result": "0",
  "side": "head"
}

Endpoints

• /number returns a numerical code
• /alphanumeric returns an alphanumerical code
• /uuid returns an UUID
• /ulid returns an ULID (see ulid/spec)
• /ksuid returns a KSUID (see segmentio/ksuid)
• /dice is a shortcut for /number?min=1&max=6
• /coin is a shortcut for /number?min=0&max=1 and returns heads or tails
• /healthz is the health endpoint

Optional parameters

length

The length parameter determines the length of the returned code. The default length is 6. Setting the length to 0 or less uses the default of 6. The highest allowed length is 100. A length higher than 100 gets reduced to 100.

min/max

Instead of the length parameter you can submit a pair of min and max parameters for the lower and upper threshold of the numerical onetimecode.

group_by/group_every

Groups the returned code in segments of the length of group_every, divided by a single character given by group_by. Works with both or one of the params. group_every has a default of 4, group_by has a dash (-) as default value. Does not work if group_every is larger than the requested length of the code.

Applies only to /number and /alphanumeric.
