How Lookups Are Counted Across Ideal Postcodes Address Search and Validation APIs
Updated 30 Dec 2020
Each account can produce one or more API Keys. These Keys are used to access addressing data.
Each Key has its own lookup balance. This means usage from one key does not affect the balance of the other.
A lookup balance is our form of credit, often purchased ahead of time, which generally permits one valid address search.
Each postcode search which returns at least one premise deducts one lookup from your Key balance.
A postcode search can return a maximum of 100 premises. If you are using the Multiple Residence dataset and retrieve more than 100 addresses, each additional page is 1 lookup.
Invalid postcodes do not affect your balance.
Our canonical test postcode, which does not affect your balance, is ID1 1QD.
Each address search that returns at least one premise deducts 1 lookup from your key.
Empty address searches do not affect your balance.
Our test address query is also ID1 1QD.
Retrieving a list of suggestions for a given address query does not affect your Lookup Balance. However, resolving a full address for a suggestion deducts 1 lookup.
Note that the suggestion API must be used in conjunction with the address resolution APIs, i.e. you must intend to resolve a full address for at least one of your search suggestions. Consistently failing to do so violates our Terms of Service.
