Is the BNBCalc API a good AirDNA API alternative?

Yes, if you want to start without a sales call. The BNBCalc API is self-serve at $0 a month plus $0.20 per successful report, and one call returns a full property analysis with comparables, cash flow and a hosted report.

Who should use the BNBCalc API?

Lenders, CRMs, proptech teams and real estate tools that need a property-level Airbnb underwrite inside their own software, with a published per-report price and no annual contract.

Can my clients read API reports on their phone?

Yes. Every call returns a link to a hosted BNBCalc report that reads well on a phone, so you can send it to a client without building your own report screen.

BNBCalc API vs AirDNA API for developers

Q: How much does the BNBCalc API cost?

It's $0 a month plus $0.20 for each successfully created report, and $0.10 more for each AI step that completes, such as AI comps or AI expense estimates. Failed requests are free, and there's no monthly minimum.

Both put short-term rental data inside your own software. The BNBCalc API is self-serve, publishes its per-report price and returns a full property underwrite in one call, while AirDNA's API is sold through its sales team and covers a wider set of market and listing endpoints.

The short answer

For most developers, the BNBCalc API is the easier place to start. You subscribe for $0, create a key yourself and pay $0.20 per successful report, and each call returns a full property analysis with comparables, cash flow and a hosted report. AirDNA's API is sold through sales, with no published price and annual terms.
