Fiat → stablecoin — `client.onramp`. Three steps, in this order and no other: **quote** (a price, valid for about five minutes), **payin** (created FROM that quote, and what returns the funding instructions the payer acts on), then the money arrives off-band and the payin status moves on its own. There is no structure class here on purpose. A payin has no action of its own — it is a mirror of the provider's record, read and re-read — so an object with a client back-reference would carry a `fetch()` and nothing else.

## Constructor

### OnrampManager

```ts
constructor(client: Client)
```

**Parameters**

- `client`: [`Client`](https://dev.cosmospay.lat/docs/sdk/definitions/server/client/)

## Properties

### client

```ts
readonly client: Client
```

**Type** [`Client`](https://dev.cosmospay.lat/docs/sdk/definitions/server/client/)

## Methods

### quote()

Price a payin. The quote expires — check `expires_at` before using it.

```ts
quote(options: CreatePayinQuoteOptions): Promise<PayinQuoteData>
```

**Parameters**

- `options`: `CreatePayinQuoteOptions`

**Returns** `Promise<PayinQuoteData>`

### createPayin()

Create a payin from a quote. The response carries the funding instructions.

```ts
createPayin(options: CreatePayinOptions): Promise<PayinData>
```

**Parameters**

- `options`: `CreatePayinOptions`

**Returns** `Promise<PayinData>`

### payins()

List this consumer's payins (paginated).

```ts
payins(options?: ListPayinsOptions): Promise<PayinPage>
```

**Parameters**

- `options` _(optional)_: `ListPayinsOptions`

**Returns** `Promise<PayinPage>`

### payin()

One payin. Served from the local mirror, refreshed from the provider when it is stale — so this is the right call to poll, not the provider's own API.

```ts
payin(id: string): Promise<PayinData>
```

**Parameters**

- `id`: `string`

**Returns** `Promise<PayinData>`

### createTrustline()

Build the unsigned trustline transaction an address needs before it can hold the stablecoin the ramp pays out in. The envelope comes from the gateway, so a wallet signing it must decode and bound it first — the issuer it names is the one the payout will use, and it is not known to the caller in advance.

```ts
createTrustline(options: CreateTrustlineOptions): Promise<TrustlineData>
```

**Parameters**

- `options`: `CreateTrustlineOptions`

**Returns** `Promise<TrustlineData>`

### createVirtualAccount()

Open a virtual account (a permanent bank reference) for a verified receiver.

```ts
createVirtualAccount(receiverId: string, options: CreateVirtualAccountOptions): Promise<VirtualAccountData>
```

**Parameters**

- `receiverId`: `string`
- `options`: `CreateVirtualAccountOptions`

**Returns** `Promise<VirtualAccountData>`

### virtualAccounts()

A receiver's virtual accounts.

```ts
virtualAccounts(receiverId: string, options?: ListPayinsOptions): Promise<VirtualAccountData>
```

**Parameters**

- `receiverId`: `string`
- `options` _(optional)_: `ListPayinsOptions`

**Returns** `Promise<VirtualAccountData>`
