# Available tokens (payor)

> List tokens available to a payment session.

## Overview

Use this method to list tokens the payor can use for the current invoice/session context.

## Authentication

Requires `x-session-token` + `x-signature`.

## Request

### List available tokens (payor/session)

```ts theme={null}
const tokens = await pepay.paymentSessions.listAvailableTokens({
  mode: 'monitored',
  network: 'base',
  available_only: true
});
```

## Response

Example response (truncated):

```json theme={null}
[
  {
    "id": 123,
    "token_symbol": "USDC",
    "token_name": "USD Coin",
    "token_type": "erc20",
    "network": "base",
    "token_decimals": 6,
    "token_address": "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
    "requires_memo": false,
    "photo_uri": "https://assets.coingecko.com/coins/images/6319/small/USD_Coin_icon.png"
  }
]
```

### Underpaid behavior

If the invoice is `underpaid`, this endpoint returns only the locked token for the original network.

### Availability filtering

Use `available_only: true` to return only tokens that are currently available for the invoice amount. Otherwise, the response includes unavailable tokens with `availability_status` and `unavailable_reason` populated.

## Errors

* `401` invalid session token/signature

## Examples

* Use `network` + `mode` filters to keep the list aligned to your checkout UI and the invoice’s active network.
