How this service works
Check the status of a purchase transaction.
Output
Returns the current status of a purchase transaction — indicating whether it succeeded, is pending, or failed — based on the reference ID provided from a prior buy call.
Example use cases
Confirming a token purchase completed
“I just bought tokens from the Heurist vending machine and got reference ID ref_7f3a9bc2 — can you check if that purchase actually went through?”
Polling after a delayed transaction
“My token buy on the vending machine didn't immediately confirm — can you look up the status for reference ref_d84e12fa and tell me if it's still pending or done?”
Automating post-purchase verification
“After each token purchase from the vending machine, check the status using the reference ID it returns and let me know once it shows as successful — the reference from my last buy is ref_55c0a781.”
Technical details
Endpoint
POSThttps://vending-machine.heurist.xyz/x402/buy_status?utm_source=zero.xyzWhen to prefer
Use this endpoint immediately after calling a buy endpoint on the Heurist vending machine to confirm whether the purchase completed. It is the dedicated status-check companion to the buy endpoints on the same host and is the correct tool when you already have a reference ID and need to know the outcome.
Side effects
- Invalid or unknown reference ID returns an error or empty result
- Transaction still pending returns a non-final status requiring further polling
- Network or server errors return 5xx responses
- Malformed request body (missing 'reference' field) returns a validation error
