    BASE167
    ● healthy

    A meme coin on Base you cannot buy from the project, only claim, and only with 167 or more Base transactions -- plus Degen Games, a monthly on-chain trading competition for holders ranked by percentage gain rather than wallet size. Everything works without a browser: no login, no session, no cookie and no CAPTCHA anywhere in the journey. Actions that touch the chain return an unsigned transaction for the user's own wallet to send; this service never signs and never holds keys.

  • Pay-per-call data & web tools for AI agents. x402 micropayments in USDC or USDT on Base (eip155:8453), $0.002–$0.05 per call, 3 free calls per wallet, no API key. Payment is a signed EIP-3009 authorization capped at the quoted amount — never send private keys.

  • USDC payments on Solana for agents. Privy holds the wallet keys. An agent receives an API key, not the private key. Outgoing USDC transfers are 0.25% through December 31, 2027. Incoming transfers, payment links, and x402 payments are 0%. On a GotSOL.app send, the Solana network fee is paid in USDC and the sender does not need SOL. The wallet that signs an x402 payment pays the Solana network fee in SOL.

  • The .ai Agent ID mint on Solana. Let AI Agents light up SOL. Holders of a .ai Agent ID buy GENAI shares through a public HTTPS JSON API and sign with Binance Agentic Wallet (baw CLI, Solana CT_501: contract-call preview/execute of the API-built transaction) or any Solana wallet; GENAI is claimed after the GENAI/SOL pool opens. Interaction is REST (HTTP+JSON) as described in skill.md; the agent signs its own transactions.

  • Public REST API for the Nolus Protocol webapp (app.nolus.io). Serves live protocol data: prices, leases, pools, staking, governance, referrals. Write endpoints return unsigned transaction payloads that the caller signs with their own wallet. The authoritative machine-readable contract is the OpenAPI 3.1 document at /api/openapi.json. Guide: https://docs.nolus.io/agentic-workflows AGENT ROUTING, pick the surface that matches where the agent runs: • REST + WebSocket (this card): address-parameterized queries from any HTTP client; write endpoints compose unsigned txs for the user's wallet to sign. • In-page WebMCP (in supportedInterfaces below): VIEW + CONNECT + NAVIGATE ONLY, runs inside the user's browser tab on app.nolus.io. Tools auto-bind to the already-connected wallet (no address parameter). Designed for browser-integrated agents to inspect the user's live session and drive the UI. Does NOT sign or broadcast transactions and never will be. Signing remains the wallet popup's responsibility. For tx execution, compose through the REST API for the user's wallet or hand the user to the dApp's UI flow. • nolusd CLI (https://github.com/nolus-protocol/nolus-core/releases): for agents outside the browser. Queries any Nolus contract and builds, signs and broadcasts transactions with a key kept on the user's machine.
