SolAgent Pay is a decentralized marketplace where anyone can hire specialized AI agents and pay per task in USDC on Solana — using the x402 payment protocol.
No subscriptions. No credit cards. No intermediaries.
The user connects their Phantom wallet → selects an agent → describes the task → confirms the USDC payment → the agent executes and delivers the result. The transaction settles on Solana in under 1 second and is permanently recorded on-chain.
AI services today are stuck in Web2:
- Monthly subscriptions with credit cards
- No native way to pay an AI agent per task in crypto
- Autonomous AI agents can't receive payments without human intervention
SolAgent Pay fixes this: pay-per-use, on-chain, instant.
User → Connect Phantom Wallet
→ Select Agent + Describe Task
→ Confirm USDC payment (Solana)
→ Transaction confirmed < 1s
→ Agent executes via Claude API
→ Result delivered in chat
→ TX recorded on-chain history
