# Services

> The Services enum for getAllowance, approve, and sign.

Use with `getAllowance`, `approve`, and `sign` when specifying the DZap service:

```typescript theme={null}
import { Services } from "@dzapio/sdk";

Services.trade;  // "trade" - swaps and bridges
Services.dca;    // "dca"  - DCA operations
Services.zap;    // "zap"  - Zap operations
```

There is no `Services.swap`; use `Services.trade` for swap/bridge.
