How long does it take to get a response from your API once we submit the address for validation? Do you just provide a response if it's a valid address or do you also provide correction options when numbers or characters are transposed? I would like to evaluate this product for use at my work.
Including external latency, the response will come often come back around 160ms (although this varies widely depending on many factors). Our SLA guarantees sub-100ms response times (not including external network latency). You can always check out response times on our status page, and you can ping our servers to get a real-time idea of the actual delay.
The LiveAddress API works by verifying that a given address exists. If you put in a non-existent address you will get an empty result:
[ ]. This is because it is not a valid address. We return candidates when there are multiple ambiguous results. However, we don't give surrounding addresses as suggestions for an invalid address. The reason for this is a privacy issue. We can help you take a dirty address and clean it if there are spelling issues or some parts are missing but we can't make something out of nothing.
