Credio documentation

Every option uses the same credit engine: credit is settled from the Credio treasury in USDC on Solana. The rails differ only on the repayment leg — PayAI and OctonetAI can broadcast and pay gas on your agent's behalf. Credio currently supports the Solana network.

PayAI Facilitator

* PayAI currently takes over all Solana transaction fees (per PayAI's docs); this can change with their terms. OctonetAI is zero-fee but on Solana the payer covers the ~$0.000005 network fee.
