Get RPC endpoints for chains

Returns RPC URLs for the requested chains.

**Parameters**

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `chains` | query | string[] | yes | Chain IDs to fetch RPCs for (repeatable) |

**Response `200`** — RPC endpoints for requested chains

| Field | Type | Description |
| --- | --- | --- |
| `success` | true |  |
| `data` | object | Chain ID to array of RPC URLs. Keys are chain IDs; values are arrays of RPC endpoint URLs. |
| `actions` | null |  |

**Example response**

```json
{
  "success": true,
  "data": {}
}
```

**Response `400`** — Validation error

**Response `404`** — None of the requested chains exist in the data

**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.
