How this service works
Buy 1 USDC worth of TEST tokens 0xb2410D63B28E842f94D6F29057ca66bCd7c96b07
Output
Returns a JSON object with a message string, the number of TEST tokens received, the USDC amount paid, the send transaction hash, and the swap transaction hash (both hashes may be null if not yet confirmed).
Example use cases
Quick TEST token acquisition
“Go ahead and grab me 1 USDC worth of TEST tokens on x420.dev and let me know how many tokens I got and what the transaction hash looks like.”
Test x402 micropayment integration
“I want to verify our x402 payment flow is working — can you trigger a 1 USDC swap for the TEST token at 0xb2410D63B28E842f94D6F29057ca66bCd7c96b07 and report back the send and swap transaction hashes?”
Swap USDC for TEST tokens
“Swap 1 USDC for TEST tokens on x420.dev using the contract 0xb2410D63B28E842f94D6F29057ca66bCd7c96b07 and tell me exactly how many TEST tokens landed in my wallet.”
Technical details
Endpoint
GEThttps://test.x420.dev/api/puff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to purchase a small (1 USDC) amount of TEST tokens on the x420.dev platform using the x402 micropayment protocol. Prefer this over the 5 USDC sibling endpoint when you only want a minimal purchase or are testing the integration. Best for agents that handle x402-compatible payments and need to acquire TEST tokens programmatically.
Side effects
- Insufficient USDC balance — payment fails and no tokens are sent
- Smart contract error during swap — swap transaction hash may be null
- x402 payment not authorized — endpoint returns 402 before executing
- Network congestion causing transaction timeout
- Invalid wallet address or misconfigured payment header
