How this service works
Buy custom USDC amount worth of x420 tokens 0x68e284F21D04D4D62398C290EC3EF41C97F80b07
Output
Returns a message confirming the purchase, the number of x420 tokens received, the USDC amount paid, and the on-chain transaction hashes for both the USDC send and the token swap (which may be null if not yet available).
Example use cases
Spend exact USDC on x420
“I want to buy exactly $10.50 worth of x420 tokens using USDC — can you execute that swap for me?”
DCA into x420 tokens
“As part of my weekly crypto routine, go ahead and purchase $25 worth of x420 tokens with my USDC right now.”
Small x420 test purchase
“I'd like to dip my toes in — buy me $0.75 worth of x420 tokens with USDC and show me the transaction details.”
Technical details
Endpoint
POSThttps://x420.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 x420 tokens — especially amounts other than the fixed $1 or $5 tiers offered by sibling endpoints. Ideal for agents that need precise control over spend amount (e.g. $10.50, $0.75).
Side effects
- Invalid or non-numeric USDC amount string returns an error
- Insufficient USDC balance in the calling wallet causes transaction failure
- Token liquidity too low for the requested swap amount
- On-chain transaction reverted, returning null transaction hashes
- Network congestion causing timeout or delayed transaction confirmation
- Amount below minimum threshold (e.g. less than 0.01 USDC) rejected by contract
