The Credit Layer for AI Agents
Credius provides credit and liquidity to AI agents operating on the x402 protocol. When agents run out of funds, the protocol keeps them working with instant, on-chain credit on Solana.
Micro-credit for AI Agents
Instant USDC credit for x402 payments exactly when agents need it most.
Automated Protocol
Zero manual reviews: credit approval is instant and trustless, every repayment verified on-chain.
Instant Credit Approval
Trustless, secure credit caps with automatic on-chain debt tracking.

x402
PayAIContinuous operations for autonomous agents
AI agents now pay per call using x402. But when a wallet is empty or missing, the agent's tasks stop. Credius fills this gap with secure, controlled credit at the protocol level.
AI Agent Request
Agent receives a 402 (Payment Required) error and initiates an x402 payment for an API call.
Credit Activated
If the agent has insufficient funds, Credius protocol credit is enabled automatically.
Pay-per-Call
Credit is used until top-up or the cap is reached, ensuring the AI agent keeps working.
All transactions verified on-chain
From 402 to settled, in one flow
Every guard runs before a single token leaves the treasury. Watch the full credit lifecycle, end to end.
402 Payment Required
The agent hits a paid x402 endpoint with an empty wallet.
Agent requests credit
Own wallet first; Credius is the fallback when funds run dry.
Credius validates
Tier, lifetime cap, wallet age and pool limits, all checked.
Treasury pays in USDC
USDC SPL tokens are sent to the service on Solana.
Service grants access
The agent receives the resource; debt is recorded on-chain.
Agent repays
USDC returns to the treasury, verified on-chain, debt cleared.
Simple, transparent, and autonomous
Credius integrates directly with the x402 payment flow. When a payment fails due to missing funds, the agent automatically receives limited credit that it repays on-chain.
Credit Cap
Each agent has a secure, progressive credit limit across all transactions for safety.
Debt Tracking
All credit issued is tracked on-chain and in the database under the agent's unique ID.
On-Chain Transparency
All payments and balances are verifiable on the Solana blockchain.
$CREDIUS powers the credit pool
Credit doesn't come from nowhere, it's funded by the token. Creator fees from every $CREDIUS trade flow straight into the treasury that backs agent micro-credit. The more the token is used, the deeper the liquidity that keeps AI agents running.
That makes $CREDIUS the economic engine of the protocol: a self-reinforcing flywheel that aligns holders, developers, and agents around one goal, a resilient, always-on agent economy.
