RelAI introduces two payment code models on SKALE. Payment Requests: merchant creates a code, buyer pays. Payment Codes: buyer pre-signs a code, merchant redeems. Both use EIP-3009, both settle with zero gas.
The @relai-fi/x402 SDK now supports Dual-Channel payments — x402 and MPP (Machine Payment Protocol) running through the same middleware. One protect() call, two payment rails, and every plugin works identically across both.
The @relai-fi/x402 SDK now has four ERC-8004 plugins: score(), feedback(), solanaFeedback(), and submitRelayFeedback(). Build verifiable on-chain reputation for your API in minutes.
RelAI now supports Crossmint Server Wallets — persistent, backend-controlled wallets that let AI agents pay for services autonomously, without any user session or private key management.
x402 micropayments are instant and irreversible. If the endpoint is down, your money is gone. We built four SDK plugins that make sure buyers never pay for a broken service.
The @relai-fi/x402 SDK bridge plugin lets buyers pay from Solana, Base, Avalanche, or any supported chain — even when your API only accepts a single network. No bridge UI, no manual swaps, no extra infrastructure.
The @relai-fi/x402 SDK now supports plugins. The built-in Free Tier plugin lets you offer free API calls per buyer before x402 payment kicks in — three lines of code, zero infrastructure.
Add a free trial to any monetised API in seconds. Set per-user limits, a global cap, and a reset period — RelAI handles the counting so you never touch your server.
The RelAI bridge extension lets any x402-protected API accept payment from any supported network and deliver USDC to the merchant on any other supported network. Pay on Solana, receive on SKALE Base — or pay on SKALE Base, receive on Solana. As more networks are added, all directions become available automatically. **Slug**: bridge-extension-x402
