}About the commonwealthbank.com.au API
The CommBank Loans API exposes loan product data from Commonwealth Bank of Australia across 3 endpoints. get_all_loans combines home and personal loan data into a single response, while get_home_loans returns principal-and-interest rates, interest-only variants, wealth package tiers, and LVR-based margins, and get_personal_loans returns interest and comparison rates for Fixed Rate, Variable Rate, and Secured personal loan products.
What the API covers
The API returns structured loan product data from Commonwealth Bank (CommBank), Australia's largest retail bank. It covers two loan categories — home loans and personal loans — across three endpoints. All endpoints are parameterless; you call them and receive the full current dataset for that category.
Home loan data (get_home_loans)
get_home_loans returns an array of home loan product objects. Each object includes an id, name, type, and fees, plus a variation structure that carries rate details. Variations distinguish principal-and-interest from interest-only repayment types, and include wealth package product variants. Rates are expressed alongside LVR-based margin tiers, so you can see how the advertised rate shifts across different loan-to-value bands. This is the data set useful for rate comparison tools and mortgage calculators.
Personal loan data (get_personal_loans)
get_personal_loans returns personal loan products including Fixed Rate, Variable Rate, and Secured loan types. Each record includes product_name, source_url, all_detected_rates_pa, and detected_comparison_ra. The comparison rate field is particularly useful for total-cost comparisons, as it factors in fees that the headline rate omits.
Combined endpoint
get_all_loans merges both datasets into one response. It returns a metadata object (institution name and notes), home_loan_products, and personal_loan_products. Use this endpoint when you need a complete picture of CommBank's consumer loan range in a single call.
- Build a home loan rate comparison tool that tracks CommBank's LVR-based margin tiers over time
- Monitor CommBank's advertised vs. comparison rates on personal loans to surface total cost differences
- Feed current CommBank interest rates into a mortgage repayment calculator
- Alert users when CommBank's fixed or variable personal loan rates change
- Aggregate CommBank home loan fees alongside rates for side-by-side lender analysis
- Track wealth package rate variants separately from standard home loan products
- Populate a financial research dashboard with up-to-date CommBank consumer loan data
| Tier | Price | Credits/month | Rate limit |
|---|---|---|---|
| Free | $0/mo | 100 | 5 req/min |
| Hobby | $30/mo | 1,000 | 20 req/min |
| Developer | $100/mo | 5,000 | 250 req/min |
One credit = one API call regardless of which marketplace API you call. Exceeding the rate limit returns a 429 response. Authenticate with the X-API-Key header.
Does Commonwealth Bank have an official public developer API for loan rates?+
What does `get_home_loans` return beyond the headline interest rate?+
fees, type, and a variation structure that covers repayment type (principal-and-interest vs. interest-only), wealth package variants, and LVR-based margin tiers. This means you can reconstruct the effective rate for a given loan-to-value ratio and product configuration, not just the headline advertised rate.
