Two Ways to Pay: Payment Requests and Payment Codes on SKALE
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.
Dual-Channel Payments: One SDK, Two Protocols - x402 and MPP Side by Side
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.
ERC-8004 Reputation Plugins: On-Chain Trust for Every x402 API
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.
Your AI Agent Now Has Its Own Wallet
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.
Stop paying for broken x402 endpoints - four plugins that fix the problem
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.
SDK Plugins: Give Buyers Free API Calls Before Payment Kicks In
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.
Agents Can Now Bridge Tokens Across Chains. Programmatically.
The RelAI Management API now exposes bridge endpoints. AI agents can quote, check balances, and execute cross-chain USDC transfers between Solana and SKALE Base — programmatically, using x402 payments. No UI. No human in the loop.
RelAI Integration with OnFinality: AI Agent Coordination for Web3 Infrastructure
OnFinality integrates RelAI to offer Ethereum RPC via x402 with on-chain, pay-per-request settlement — no signup, no API keys, no monthly plans.
WebSocket in x402 Relay: What Problems We Solve by Introducing WS
Why we introduced WebSocket transport in x402 Relay, which bottlenecks it removes, and how HTTP fallback keeps paid API calls reliable.
