API Reference - Ideal Postcodes
# Getting Started ## Overview ### Access All API methods are either a `GET`, `POST` or `OPTIONS` request. The API communicates over both HTTPS and plain HTTP using IPv4 and IPv6. We recommend using HTTPS only although HTTP is available. We use appropriate HTTP status codes where possible to indicate the request status. ### Rate Limiting Each IP address is rate limited at 30 requests per second. Tripping the rate limit will result in a 503 response. The autocomplete API also has an additional rate limit. If you expect to breach the limit please contact us and we can move you to an endpoint with a higher limit. ### JSONP JSONP requests are supported. Include a `callback=` in your request as a query parameter. Your results return wrapped in a function designated by your request. ## Authentication Most requests require an **API key** for authentication. Authenticate by passing an `api_key` as part of the query string. For example: ``` api.ideal-postcodes.co.uk/v1/autocomplete/addresses?api_key=iddqd&q=parkside ``` Alternatively, authentication can be transmitted via the `Authorization` header using the following scheme: ``` Authorization: api_key="iddqd" [other_key="foo"] ``` ## Versio
