Bridge Plugin: Cross-Chain Payments in Three Lines of Code
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.

Bridge Extension for x402 - Pay on Any Chain, Receive on Any Chain
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
Bridge Any Supported Network - Solana, SKALE Base, and Testnets
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.
Cross-Chain Payments, Both Ways - Solana ↔ EVM on a Single API
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 Includes a Full Management API Client
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.
How AI Agents Authorize Themselves with RelAI
Walk through the full agent authorization flow on RelAI — from consent request to autonomous paid API calls, step by step with real HTTP examples.
Agent Service Keys: Let AI Agents Call APIs on Your Behalf
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.
AI Agents Now Build On-Chain Reputation Through RelAI and SATI
Every AI agent authorized through RelAI now automatically receives a SATI identity NFT on Solana and builds verifiable on-chain reputation with every paid API call.
