How this service works
Buy $4.00 USDC worth of tokens from the vending machine. The token launch must be open to buy, and the allocation cap must not have been reached.
Output
Returns a transaction confirmation including the purchase status, the amount of tokens received for the $4.00 USDC spent, and the recipient address that received the tokens.
Example use cases
Participating in a new token launch
“I want to buy $4 worth of the new token at address 0x1234abcd... from the Heurist vending machine — send them to my wallet 0xWallet...”
Automated agent buying tokens on my behalf
“Whenever a new token launch opens on the Heurist vending machine, buy $4 worth of tokens at address 0xToken... and deposit them into my address 0xMyWallet...”
Testing token purchase flow with small allocation
“Go ahead and purchase $4 USDC worth of the token at address 0xTestToken... from the vending machine and keep them in the default caller address.”
Technical details
Endpoint
POSThttps://vending-machine.heurist.xyz/x402/buy4x?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you want to purchase exactly $4.00 USDC worth of tokens in a single transaction. Use the $3 endpoint for a smaller purchase or the $5 endpoint for a slightly larger one. This is ideal for agents automating fixed-denomination token buys in open Heurist vending machine launches.
Side effects
- Token launch is not open for buying — returns an error indicating the sale is closed
- Allocation cap has already been reached — returns an error that no more tokens are available
- Invalid or non-existent token address — returns a validation error
- Insufficient x402 payment — payment of $4 USDC not confirmed, transaction rejected
- Invalid recipient address format — returns a schema validation error
