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
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 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.
The RelAI Bridge now supports every network in the RelAI ecosystem. Bridge USDC between Solana and SKALE Base on mainnet, or test with Solana Devnet and SKALE Base Sepolia - the same bridge, all directions.
RelAI now supports bidirectional cross-chain payments. An API on Base can accept Solana USDC. An API on Solana can accept USDC from Base, Polygon, or Avalanche. One endpoint, every chain.
The RelAI SDK now ships a built-in Management API client. Create APIs, set pricing, read analytics, and bootstrap agent service keys — all from TypeScript or JavaScript, with zero extra dependencies.
Walk through the full agent authorization flow on RelAI — from consent request to autonomous paid API calls, step by step with real HTTP examples.
RelAI now lets you link any on-chain AI agent to your account. The agent proves ownership by signing a message with its NFT owner wallet. Once linked, it calls APIs using an X-Service-Key — no crypto, no x402, billed to your account.
