# List Country Codes

`GET /api/v2/tech/country-options`

Returns the ISO 3166-1 **alpha-3** country codes accepted by the Agent Primitive search endpoints. Ordered by company volume so the highest-coverage codes (USA, GBR, CHN, FRA, IND, DEU, ...) come first.

**Where these codes are used:**
- `GET /api/v2/tech/companies` - `hq_country_code` parameter.

One-shot discovery call - static, safe to cache.

## Response `200`

    - `code` string, required — ISO 3166-1 alpha-3 country code (e.g. 'USA', 'GBR', 'DEU').
