Automotive inventory API Build on verified inventory, in real time.
ÆTHR gives your product standardized, verified dealer inventory through one open API. Onboard dealers fast. Call it anytime and get inventory as it stands right now.
You're building on data you can't see.
Inventory reaches you from whoever's willing to send it. Nobody tells you what's missing, stale or wrong. You find out when a dealer does.
Bad inputs make good products look broken.
Your tool quotes a sold vehicle. Your assistant gets the trim wrong. The dealer doesn't see a feed problem. They see your product.
Get your sprints back.
Every new source is another format to map, test and keep alive. Every new dealer waits on a feed. ÆTHR standardizes all of it before it reaches you, so one integration covers every dealer.
Don't wait for the next feed.
Most inventory arrives on a schedule, then needs mapping all over again. ÆTHR skips the wait. Call the API when your product needs data, and you get the dealer's inventory as it stands right now, already standardized. Prism checks the dealer's live website, so you know what shoppers actually see.

How HeyG puts the right vehicle on every call.
What you can build on verified inventory.
One open automotive inventory API. Every dealer's inventory.
Standardized records, current every time you call, through one open API. The dealer owns the data and chooses who reads it. When a dealer picks your product, their inventory is ready for you.
Read the API docsThe format set on the dealer's feed: JSON, XML or CSV. Each response includes the fields selected on that feed, under the names that feed uses. Set the mapping once, and every dealer's inventory arrives in the shape your product expects. JSON timestamps are in UTC.
Each dealership has its own API key. You get it one of two ways. The dealer gives it to you, or, with the dealer's consent, you manage their ÆTHR account on their behalf and get the key there. Send it in the X-API-Key header over HTTPS. One key returns one dealer's inventory, so the dealer stays in control of who reads it. Keep keys out of client-side code and public repositories.
60 requests per 60 seconds for each client address. Every response carries headers showing your limit, what's left and when the window resets. Go over and you get a 429 with the number of seconds to wait. Rotating keys doesn't raise the limit.
Each call returns the dealer's inventory as it stands at that moment. You don't wait on a scheduled export or the next batch file. Call when your product needs the data. Ask for the full inventory in one response, or page through it.
Yes. Start a free trial, connect one dealer and call the API with that dealer's key. When the trial ends, calls return a clear "trial expired" error until the account is upgraded. No credit card required to start.
Start with one dealer.
