The Autosuggest API must respond within 100 Ms under all circumstances on a stable internet connection although on an unstable one, response times may vary.

Transaction Information

One request using the API link will be considered as one transaction. For any string in the input, the output will be list of address matching with that string. This is considered as one transaction. So, if the autosuggest response does not contain any data it won’t be counted.
