Payment Networks

These are the networks used to settle USDC payments. They are separate from the chains targeted by the API. The number of Credits granted per 1 USDC is the same regardless of which network is used.

Network	Chain ID	1 USDC 당 Credits
Base Mainnet	eip155:8453	1,000,000
Solana Mainnet	solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp	1,000,000

Pricing Reference

• PPU minimum amount: 0.001 USDC for all methods
• Batch JSON-RPC (PPU): Max(sum(각 메서드 비용), max(각 메서드 ppu_min_amount))
• Minimum Credit top-up amount: 0.01 USDC
