Hey PH! 👋 I built FindBSB after getting frustrated with the lack of a decent BSB lookup API in Australia. Every time I needed to validate BSBs in a payment form I had to either scrape a website or parse AusPayNet's CSV manually. So I built a free JSON API — no auth, no signup, just HTTP. Single lookup, bulk validation up to 500 BSBs, filter by bank/state/suburb. It's been running for a few weeks and I've just added it to RapidAPI too. Happy to answer any questions and would love feedback from devs building Australian payment systems!

For anyone wanting to test it right now — no setup needed, just run this in your terminal:

curl https://findbsb.com.au/api/bsb/062-000

Or hit the live playground at findbsb.com.au/api

Would love to know if you're building anything in the Australian payments space — always keen to hear what BSB-related problems people are actually running into.
