## Known failure modes

- Token launch is not open for buying — returns an error indicating the sale is closed
- Allocation cap has been reached — purchase is rejected
- Invalid or unrecognized token address — returns a bad request error
- Insufficient USDC payment — payment validation fails
- Recipient address is malformed — request rejected with validation error

## How this service works

Buy $1.00 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 the amount of tokens acquired for $1.00 USDC, the recipient address credited, and transaction details. May indicate failure if the launch is closed or the allocation cap has been reached.
