A Base network block (latest, or by number): hash, time, transaction count, gas used and limit, base fee and fee recipient.

What is this Base network address? Wallet or contract, bytecode size, upgradeable proxy and implementation, token standard (ERC-20, ERC-721, ERC-1155) with name and symbol, owner, nonce and balances.

Agent-readiness audit of a website: can AI agents and assistants find and use it? Checks llms.txt, agent card, MCP endpoint, OpenAPI, pay-per-call manifest, sitemap, and robots.txt rules for AI crawlers. Score, what was found, and fixes.

Are these domain names free to register? Checks up to 10 names against the public registries: registered (with expiry) or not found (likely available).

Cheapest real end-to-end test of your pay-per-call (HTTP 402) client: pay US$0.001, get back proof of what was paid (payer, amount, network, timestamp) and the request you sent. Use it to check a wallet, a client library or a facilitator before buying something bigger.

Check a Base network token contract before your agent buys, accepts or lists it: live on-chain facts (name, symbol, decimals, supply, owner and whether ownership is renounced, upgradeable proxy, owner's and contract's own holdings, burned share) with red flags and a short AI verdict. Facts, not financial advice.

Check an email address before sending: syntax, whether the domain exists and accepts mail (MX records), disposable or free-mail provider, role account (info@, support@), and a verdict.
