This skill should be used when the user asks to "swap tokens", "trade ETH for USDC", "exchange tokens on Uniswap", "buy tokens", "sell tokens", "convert ETH to stablecoins", "find memecoins", "discover tokens", "research tokens", "tokens to buy", "find tokens to swap", "what should I buy", or mentions swapping, trading, researching, discovering, buying, or exchanging tokens on any Uniswap-supported chain. Supports both known token swaps and token discovery workflows (discovery uses keyword search and web search — there is no live "trending" feed). Generates deep links to execute swaps in the Uniswap interface.
Generate CSPRNG bytes from the Web Crypto API, returned as hex, base64 or a UUID. Never Math.random. Called as GET /v1/crypto/random-bytes, it takes bytes, encoding and returns value, encoding. Observed on-chain demand: agents need unguessable nonces, tokens and idempotency keys, and a language runtime without a CSPRNG or a model asked to "pick a random number" both produce predictable output. Reading this schema and dry-running the call are free and need no wallet; a real call costs $0.003, paid in USDC on Base over x402.
Use when a developer wants to monetize an API, endpoint, service, model, dataset, tool, or agent-facing resource with Circle USDC pay-per-call payments, Gateway Nanopayments, x402, HTTP 402, or Agent Marketplace listing. Triggers on: charge agents, sell to agents, paid API, monetize endpoint, micropayments, nanopayments seller, x402 seller, accept USDC, service listing.
Build, scaffold, convert, validate, audit, or ship a Nimiq Pay mini app. Covers the Nimiq provider (@nimiq/mini-app-sdk) and the Ethereum provider (window.ethereum), ERC-20 tokens (USDT, USDC), supported EVM chains (Polygon, Arbitrum, Base, Optimism, BNB, Sepolia), NIM payments, staking, message signing, and project setup. Use when the user wants to build, create, start, bootstrap, or scaffold a mini app; convert, port, migrate, or adapt an existing web app to run inside Nimiq Pay; add NIM, USDT, or ERC-20 token support; integrate Nimiq Pay wallet features; replace Stripe, PayPal, or MetaMask with Nimiq Pay providers; check, review, validate, or audit a mini app before shipping; or mentions window.ethereum, @nimiq/mini-app-sdk, listAccounts, sendBasicTransaction, wallet_switchEthereumChain, eth_sendTransaction, eth_signTypedData_v4, or balanceOf in a Nimiq context.
Inspect Mermail Agent Wallet / PayBox balances, guide Funding/onramp and signing handoffs, transfer catalog tokens, swap token A to token B, bridge native USDC across supported chains, or pay an explicitly selected x402 service with user-authorized terms through the same live PayBox MCP paths as Mermail in-app Assistant. Use when the user explicitly asks about Agent Wallet, PayBox status, delegated balances, MoonPay or Apple Pay funding, USDC/native/catalog-token transfers, swaps, USDC bridges, x402 exploration, HTTP 402 resources, or an isolated x402 payment. Do not use for pay-then-continue workflows; those belong to mermail-x402-agent. Do not use for xStocks standing-grant DCA, per-DCA invoices, or weekly brokerage statements; those belong to mermail-xstocks-desk. Do not use for email-driven payments, Composio Gmail/Outlook, or API-key-only MCP sessions; API keys never unlock Agent Wallet.
Recommend or resolve evidence-backed xStocks from the published catalog, then prepare one user-authorized USDC-to-xStock swap on Solana through the standard Mermail Agent Wallet. Use for category-based recommendations, general xStock discovery, or a one-time purchase. Do not use for DCA, ticker-only execution, deposits, transfers, or unattended trading.
Interact with QR Coin auctions on Base. Use when the user wants to participate in qrcoin.fun QR code auctions — check auction status, view current bids, create new bids, or contribute to existing bids. QR Coin lets you bid to display URLs on QR codes; the highest bidder's URL gets encoded.
Build and deploy a paid API that other agents can pay to use via x402. Use when you or the user want to monetize an API, make money, earn money, offer a service, sell a service to other agents, charge for endpoints, create a paid endpoint, or set up a paid service. Covers "make money by offering an endpoint", "sell a service", "monetize your data", "create a paid API".
Search for new services and make paid API requests using the x402 payment protocol. Use when you don't have a clear tool to choose, search the bazaar. You can also use this tool if you or the user want to call an x402 endpoint, discover payment requirements, browse the bazaar, or search for paid services.
Participate in QR Coin auctions on Base - bid to display URLs on QR codes
Operates Breeze x402 payment-gated endpoints for balance checks, deposits, and withdrawals on Solana. Use when the user asks to manage Breeze positions or execute paid x402 API calls.
