# Step 1: Check Supported Config

> Discover which assets, networks, payment modes and countries are live for onramp and offramp

<Note>
  Optional but recommended. Use these endpoints to build your asset and country pickers so users only see buy and sell routes that will succeed.
</Note>

## Configuration endpoints

Instead of probing `asset_config` pair-by-pair, use these bulk endpoints to discover what is live:

| Endpoint | Returns |
| - | - |
| [`GET /api/partner/v1/ext/ramp_order/config`](/api-reference/configuration/get-order-config) | Full support matrix in one call: every configured asset, payment mode and order type, split by direction (`buy` = onramp, `sell` = offramp). |
| [`GET /api/partner/v1/ext/ramp_order/blocked_currencies`](/api-reference/configuration/get-blocked-currencies) | Supported countries with the crypto currencies blocked in each. Pass `?country=<ISO alpha-2>` to filter to one country. |

For narrower lookups, the [Configuration](/api-reference/configuration/get-asset-config) group also exposes `asset_config`, `chain_config`, `token_config` and `payment_mode_config`.

All configuration endpoints are HMAC-authenticated like the rest of the external API.

<Tip>
  In the `config` response, read the **`buy`** direction for onramp and the **`sell`** direction for offramp. Cache the result and refresh it periodically. It changes rarely.
