Prep for a meeting
I'm meeting [name] from [company] about [topic]. Pull a brief on the company (size, funding, revenue), a profile on [name] (role, career arc, recent X posts), and flag anything in their last 10-20 tweets directly relevant.
Spot top traders
Who's been moving NVDA in the last 30 days? Pull the top 20 disclosed trades by size — name, direction, dollar amount — and flag anyone who's broken their usual pattern or hedged with options.
Research what's new in AI
Pull the most important new AI research papers from this week - arXiv, conference proceedings, lab blogs. Give me 5-8 specific papers with arXiv IDs, dates, and authors, plus 3 layered debates or launches I should track. One-line 'why it matters' per item.
Find me a domain
I'm starting an agentic payment project. Suggest ~10 names across mixed styles (invented, compound, multi-word phrases) and check each across .com plus 2-3 fitting alt TLDs. Show me everything - taken and available, with prices.
Improve my socials
Look at my X profile [@placeholder] and pull all my posts from the last 30 days. Rank by engagement (likes + retweets + replies + quotes) and show me my top 5 and bottom 5. Tell me what's working, what isn't, and what topics hit vs flopped.
Analyze BTC shorts
Get top 10 BTC/USD shorts on Hyperliquid: scan top 250 accounts via free Hyperliquid API for positions, use Goldsky Arbitrum for last week's BTC daily prices, and analyze wallet behavior (fill history, entry pattern, position size, leverage, liquidation risk, strategy type).
For sellers
Your API
is a storefront.
Agents can pay for API calls without a checkout page. Turn an endpoint into a line of revenue without adding a signup flow.
$ npm i @circle-fin/x402-batching
import { createGatewayMiddleware }
from "@circle-fin/x402-batching/server";
const gateway = createGatewayMiddleware({
sellerAddress: "0xYOUR_WALLET",
});
// Price any route. Gateway does the rest.
app.get("/run",
gateway.require("$0.01"),
handler);
// Unpaid -> 402. Paid -> 200.
// Settles in batch, credits your Gateway balance.
