+# CoinAPI
+
+## Sync overview

+[CoinAPI](https://www.coinapi.io/). It currently only supports Full Refresh
+syncs.
+
+### Output schema
+
+This source is capable of syncing the following streams:
+
+* `ohlcv_historical_data`
+* `trades_historical_data`
+
+### Features
+
+| Feature           | Supported? \(Yes/No\) | Notes                                                   |
+|:------------------|:----------------------|:--------------------------------------------------------|
+| Full Refresh Sync | Yes                   |                                                         |
+| Incremental Sync  | No                    |                                                         |
+| API Environments  | Yes                   | Both sandbox and production environments are supported. |
+
+### Performance considerations
+
+CoinAPI allows only 100 daily requests on the free plan. Use of this connector
+may require a paid plan.
+
+## Getting started
+
+### Requirements
+
+1. Obtain an API key from [CoinAPI](https://www.coinapi.io/).
+2. Choose a symbol to pull data for. You can find a list of symbols [here](https://docs.coinapi.io/#list-all-symbols-get). 
+3. Choose a time interval to pull data for. You can find a list of intervals [here](https://docs.coinapi.io/#list-all-periods-get).
+
+### Setup guide
+
+The following fields are required fields for the connector to work:
+
+- `api_key`: Your CoinAPI API key.
+- `environment`: The environment to use. Can be either `sandbox` or `production`.
+- `symbol_id`: The symbol to pull data for.
+- `period`: The time interval to pull data for.
+- `start_date`: The start date to pull `history` data from.
+- (optional) `end_date`: The end date to pull `history` data until.
+- (optional) `limit`: The maximum number of records to pull per request. Defaults to 100.
