# Types

The fields of every response and event type, and the enumerations they use.

## Lookup types

Every response type is an immutable `Data` class, as are `ResponseMetadata`, `RateLimit`, and `GRPCSchema::Schema`.

- **Fields:** Read fields with the methods named after them. `to_h`, `with`, `==`, and pattern matching work as for any `Data`, and arrays and hashes decoded from a response are frozen.
- **Optional fields:** A field typed with a trailing `?` is `nil` when the API omits it or sends `null`.
- **Decoding:** A response with a required field missing or of the wrong type raises `DecodeError`. Unknown fields are ignored so that additive API changes don't break decoding.
- **Timestamps:** Unix timestamps from the API become `Time` values in UTC, whether the API sends seconds or milliseconds.

### IPInfo
