Technical details
Endpoint
POSThttps://test9999.x420.dev/api/puff-custom?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to purchase a specific, non-standard USDC amount of TEST9999 tokens (e.g. 0.5, 10, 10.5 USDC) rather than the fixed $1 or $5 USDC tiers offered by sibling endpoints. Ideal when the caller wants precise control over how much USDC to spend.
Side effects
- Invalid or non-numeric USDC amount string — API may reject or default
- Insufficient USDC balance or allowance — transaction fails on-chain
- Slippage too high — swap may revert
- Contract address liquidity issues — swap transaction hash is null indicating failure
- Payment of $5 USDC call fee not provided — request blocked by x402 payment gate
