## When to prefer this

Use this endpoint when you want to make a small $2 USDC entry into a token launch on the Heurist vending machine. Prefer this over the $3, $4, or $5 buy endpoints when the user wants the minimum purchase tier or wants to test participation with minimal spend. Requires the target token launch to be active and under its allocation cap.

## Known failure modes

- Token launch is not currently open for purchase — returns error indicating closed or not-yet-started sale
- Allocation cap has already been reached — returns error indicating the sale is sold out
- Invalid or unrecognized token address — returns validation error
- Insufficient payment or payment processing failure via x402 protocol
- Invalid recipient address format

## How this service works

Buy $2.00 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 confirmation of the token purchase, including transaction details, the amount of tokens acquired, and the recipient address that received the allocation.
