    SubEtha is a 2nd Winner of the Superteam Japan x enXross by Tokyo Dome Side Track. Thank you @SuperteamJapan and @enXross! SubEtha builds private payments for AI agents. Its Router lets them pay APIs across supported protocols, chains and assets.

    Private requests. Verifiable API calls. Our PoC keeps request bodies hidden from SubEtha Router, while verifying the approved request reached the chosen Provider and the result came from that exchange. Paid flow tested end to end on testnet with our test Provider.

    SubEtha Router connects x402 and MPP across payment networks. Our hosted testnet demo uses @solana, @base, @arc and @tempo. Agents pay on one supported rail; APIs receive on another. Local testnet verification now covers additional chains, shown below.

    We used SubEtha Router to call @exaailabs' search API on mainnet. The agent paid USDC.e via MPP on Tempo. The Router paid Exa USDC via x402 on Base and returned the search results. A real API call across payment protocols and chains

    Privacy is the other half of SubEtha. We're building x402 payments with @zERC20io's zero-knowledge technology to reduce on-chain payment linkability and limit what payment history reveals about an agent's activity. Building an agent or paid API? Let's talk.

    Claude Code. Codex CLI. Grok Build. All three used SubEtha Router to pay for an API and retrieve its data—with human approval. Real testnet purchases, not just MCP connections. An update for @colosseum's Crypto World's Fair. #CryptoWorldsFair 1/5

    Each CLI also read our setup guide and registered the Router via MCP. Try this prompt: "Set up SubEtha Router using then list its routes. Do not purchase." Restart when prompted. Listing and quotes need no wallet. 4/5

    Building an agent or a paid API? We'd like to test your use case. Agents pay using a supported payment method; providers keep accepting theirs. Explore routes and quotes: 5/5

    We're applying to the @AdevarLabs Security Sidetrack at @Colosseum's Crypto World's Fair via @superteamearn. SubEtha Router connects AI agents and paid APIs across payment systems. We'd welcome a pre-audit of its payment verification and authorization.
