Get token list for a chain

Fetches the complete token list for a given chain, including metadata such as symbol, name, decimals, and asset group.

**Response Structure:**
- `tokens`: Object keyed by token address (lowercase) containing token metadata
- `count`: Total number of tokens in the list

**Token Metadata includes:**
- `symbol`: Token symbol (e.g., "USDC")
- `name`: Full token name (e.g., "USD Coin")
- `decimals`: Token decimals (e.g., 6 for USDC)
- `assetGroup`: Asset grouping for price lookups
- `logoURI`: Optional logo URL

**Parameters**

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `chainId` | query | string | yes | Chain ID to fetch token list for See the `ChainId` schema for the full set of supported chains. |

**Response `200`** — Token list for the chain

| Field | Type | Description |
| --- | --- | --- |
| `success` | true |  |
| `data` | object |  |
| `data.chainId` | string | EVM chain id, as a decimal string. See the `ChainId` schema. |
| `data.count` | integer | Total number of tokens |
| `data.tokens` | object | Map of token address (lowercase) → token metadata |
| `actions` | null |  |

**Example response**

```json
{
  "success": true,
  "data": {
    "chainId": "1",
    "count": 1,
    "tokens": {}
  }
}
```

**Response `400`** — Validation error

**Response `429`** — Rate limited. Unauthenticated callers share a per-IP budget; send an `x-api-key` header to lift it. Retry with exponential backoff.

**Response `500`** — Unexpected server error. Safe to retry with backoff.

**Response `502`** — An upstream data source or protocol origin failed (`error.code` is `ORIGIN_FAILED`). `error.details` carries the per-origin status. This is also what a missing or malformed required parameter currently returns, rather than a 400.
