APIBAN

REST API for sharing IP addresses sending unwanted SIP traffic

APIBAN helps prevent unwanted SIP traffic by identifying addresses of known bad actors before they attack your system. Bad actors are collected through globally deployed honeypots and curated by LOD/APIBAN.

APIBAN is made possible by the generosity of our sponsors.

This API allows you to integrate and interact with APIBAN data.

The data is provided in standard JSON responses and use HTTP Status Codes to help determine results

NOTE If you are looking to protect your PBX or SIP server without programming, you should use the free APIBAN client to automatically block traffic.

To use the APIBAN API, you will need to first obtain an API KEY. The API KEY is used for all API requests.

NOTE API KEYs are limited to one per user/email. If your organization needs multiple keys, please contact LOD.

The data is provided in standard JSON responses and use HTTP Status Codes to help determine results

The API is organized around REST. Our API has predictable resource-oriented URLs, returns JSON-encoded responses, and uses standard HTTP response codes and verbs.

Base URL

Where [KEY] is replaced with your API KEY.

For integration examples for Kamailio, Homer, and more, please visit our GitHub repo.

Authentication

Authentication with the API is made through the API KEY. If having trouble receiving an API KEY or if an API KEY needs to be replaced, please contact our support team.

Requests to the API are limited to 11 requests in 2 minutes.

Example authentication errors received from the API:

HTTP 403
{"ipaddress":"none", "ID":"unauthorized"}

HTTP 429
{"ipaddress":"rate limit exceeded", "ID":"unauthorized"}

Errors

The API will return non-2xx http status codes and descriptive responses when able to do so. Examples include:

Banned

Banned is an object returning banned ip addresses in batches of 250. An ID is provided to use when pulling the next batch. If no ID is passed, the first 250 addresses (oldest first) will be provided.

• Method: GET
• Required parameter: APIKEY
• Optional parameter: ID

Examples

GET https://apiban.org/api/[APIKEY]/banned

GET https://apiban.org/api/[APIKEY]/banned/[ID]

Where [KEY] is replaced with your API KEY and optional [ID] represents last known ID received, such as: https://apiban.org/api/abcdefg12345678/banned/9876543210

Example responses

200 {"ipaddress":["1.2.3.4","1.2.3.5"], "ID":"9876543210"}

400 {"ipaddress":["no new bans"], "ID":"none"}

Check

Check is an object returning the status of a specific ip address. A 2xx indicates a ban and a 404 indicates the ipaddress is not banned.

• Method: GET
• Required parameter: APIKEY
• Required parameter: IPADDRESS

Example

GET https://apiban.org/api/[APIKEY]/check/[IPADDRESS]

Where [KEY] is replaced with your API KEY and [IPADDRESS] is the address to check.

Example responses

200 {"ipaddress":"blocked", "ID":"9876543210"}

400 {"ipaddress":"ok", "ID":"0"}

IPsets (lists of IPs) can be used by many firewalls, iptables, and appliances (such as pfsense, opnsense, etc.) to block unwanted traffic to your network.

List

List returns a plain text ipset with control id, record count, and IPs (listed in age order from oldest to most recent).

• Method: GET
• Required parameter: APIKEY

NOTE This uses the ipset resource vs api.

Example

GET https://apiban.org/ipset/[APIKEY]/list

Where [KEY] is replaced with your API KEY. Please note that this call uses the ipset resource vs api.

Example responses

200 plain text document

403 {"ipaddress":"none", "ID":"unauthorized"}

429 {"ipaddress":"rate limit exceeded", "ID":"unauthorized"}

503 {"error":"gK10", "description":"an internal error occurred"}
