## When to prefer this

Use this endpoint when an agent needs to acquire exactly $5 USDC worth of x420dog tokens in a single fixed-amount call. Prefer over the custom-amount endpoint when $5 is the desired spend, and over the $1 endpoint when a larger position is needed in one call.

## Known failure modes

- Insufficient USDC balance — payment rejected
- Smart contract swap failure — swap transaction hash null, tokens not received
- Network congestion causing transaction timeout
- Invalid or misconfigured x402 payment header — 402 Payment Required error
- Liquidity pool insufficient for swap — transaction may revert
