# Playground

Send real requests to lookup, account, and bounded enterprise feed endpoints from this page, with your own API key, and read the response beside the schema that describes it.

An interactive playground runs here on the documentation site: enter an API key and send live requests to lookup, account, and enterprise feed metadata endpoints. It needs a browser, so use [the CLI](https://docs.synthient.com/cli) or the code samples elsewhere in these docs instead.

## What you can call here

| Endpoint                                            | Cost                                 |
| --------------------------------------------------- | ------------------------------------ |
| `GET /api/v4/lookup/ip/{ip}`                        | 1 credit                             |
| `POST /api/v4/lookup/ips`                           | 10% batch discount, rounded up       |
| `GET /api/v4/lookup/domain/{domain}`                | 1 credit                             |
| `GET /api/v4/account/me`                            | free                                 |
| `GET /api/v4/feeds/{stream}/export?limit=10`        | free, enterprise feed scope required |
| `GET /api/v4/feeds/{stream}/export/{snapshot}/meta` | free, enterprise feed scope required |

The playground limits snapshot listings to 10 entries and supports metadata only. It does not download Parquet files or open live streams: snapshot downloads redirect to presigned URLs measured in gigabytes, while the [firehose](https://docs.synthient.com/enterprise/firehose) holds a connection open for thirty minutes against a limit of one new connection every two seconds. gRPC is not reachable from a browser. Use the [CLI](https://docs.synthient.com/cli) or the [Go SDK](https://docs.synthient.com/sdk) for those operations.

## Using it from your own code

The playground is a reading aid, not an integration pattern. Do not copy its shape into an application: your key belongs on your server, not in JavaScript you ship to end users. See [Authentication](https://docs.synthient.com/authentication) for the distinction, and the [IP API](https://docs.synthient.com/ipapi) reference for the full response schema.
