Purchase flow

The typical flow is: Pick a location -> Search for number groups -> Check requirements -> Purchase (optionally reserving first).

Get Regions

GET /numbers/regions?country={ISO_CODE}

Query params: country (required) — ISO country code (e.g., US, CA, GB).

Returns regions available for the given country. Regions are available for US, CA, and GB. Required for US searches.

Response:

{
  "success": true,
  "data": {
    "regions": [
      { "id": 123, "region_name": "California", "iso_country_code": "US" }
    ]
  }
}

Get Cities

GET /numbers/cities?country={ISO_CODE}&region={REGION_ID}

Query params: country (required) — ISO country code, region (optional) — region ID from the regions endpoint. If omitted, returns all cities for the country.

Response:

{
  "success": true,
  "data": {
    "cities": [
      { "id": 456, "city_name": "Los Angeles", "iso_country_code": "US" }
    ]
  }
}

Get DID Types

GET /numbers/did-types

No query params. Returns all available number types.

Valid types: local, mobile, tollfree, national, global, sharedcost.

Response:

{
  "success": true,
  "data": {
    "did_types": [

  }
}

Get Requirements

GET /numbers/requirements?country={ISO_CODE}&did_type={DID_TYPE_ID}

Query params: country (required) — ISO country code, did_type (optional) — DID type ID to filter requirements.

Some countries require identity documents or proof of address. Check requirements before purchasing — buying without meeting them can result in the number being suspended. If the array is empty, no documents are needed.

{
  "success": true,
  "data": {
    "requirements": [
      { "description": "Proof of address required", "did_type": "local" }
    ]
  }
}

This is the main search endpoint. Query params: country (required), region_id (optional), city_id (optional), city_name_or_prefix (optional) — search by city name or area code prefix, did_type (optional) — local, mobile, tollfree, national, global, sharedcost, or all.

Response:
