## Request

A JSON body. These are the same for every action; the rest depends on the platform, below.

| Name | Type | Where | Required | What it is |
| --- | --- | --- | --- | --- |
| `platform` | string | body | Yes | The platform to read. One of the platforms this action is offered on. |
| `max_cost_credits` | integer | body | No | The most this call may cost. Over it, the call is refused for free and the answer carries the quote. |
| `Idempotency-Key` | string | header | No | 1 to 255 visible ASCII characters. The same key with the same parameters returns the first result again and is not charged twice. |

## Platforms and credits

Each platform takes its own parameters. Its own page has the full parameter and field tables and a request you can change.
