## When to prefer this

Use this endpoint when you want to participate in a token launch on the Heurist vending machine with a fixed $5.00 USDC purchase. Prefer this over the $3 or $4 tier endpoints when you want a higher allocation in a single call, and over the $4 tier when the exact $5 fixed amount matches your intent. Suitable for agents automating token launch participation at a specific price point.

## Known failure modes

- Token launch is not open for buying — returns an error indicating the sale is inactive
- Allocation cap has been reached — purchase rejected with cap-exceeded error
- Invalid or missing token address — returns validation error
- Invalid recipient address format — returns address parsing error
- Insufficient USDC payment — payment layer rejects the transaction
- Network or blockchain RPC failure — transaction cannot be submitted

## How this service works

Buy $5.00 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

A confirmation of the $5 USDC token purchase, including transaction details, tokens allocated, and the recipient address that received the tokens. May include error details if the launch is closed or the allocation cap has been reached.
