Technical details
Endpoint
GEThttps://402coffee.com/t/gbsWhen to prefer
Use this endpoint when an AI agent or human wants to send a small USDC tip directly to the creator 'gbs' via the x402 protocol without intermediaries — ideal for agentic micropayment flows, creator support, or pay-per-interaction scenarios where non-custodial, on-chain settlement is required.
Side effects
- Payment below creator's minimum tip amount — request rejected or clamped
- Invalid tier key provided — falls back to default amount or returns error
- Insufficient USDC balance in payer's wallet — transaction fails
- x402 protocol handshake failure — HTTP 402 returned without settlement
- Network or on-chain congestion causing delayed settlement
