Rate limits keep the API fast and fair for everyone. Build your integration to respect them gracefully.
Staying within quota
- Debounce postcode inputs so you only call on meaningful changes
- Cache repeat lookups for the same postcode
- Honour the retry interval on a 429 response with exponential backoff
- Queue or batch non-urgent verification jobs

Frequently asked questions
What are the API rate limits?
Limits depend on your plan and protect service quality. When you exceed them, the API returns a 429 response with headers indicating when to retry.
How should I handle a 429?
Back off and retry after the indicated interval, queue non-urgent requests, and cache repeat postcode lookups to reduce volume.
Can I increase my limits?
Yes — upgrade your plan or contact us for higher-volume needs.
