A transparent quant factor score for a US stock: Value (P/E, P/S, P/B), Quality (ROE, margins, leverage), Growth (YoY revenue & earnings) and Momentum (trailing return), each 0–100 from filing-grade fundamentals plus an equal-weighted composite. Returns every metric it scored, with labels. Factual, not advice. From x402stock, a market & economic data API (x402, USDC).

Annual time series of one World Bank indicator for a country, with latest value, prior year, and change. Indicators: gdp, gdp-growth, gdp-per-capita, inflation, unemployment, population, govt-debt, current-account, exports, fdi. Pick the country with `?country=US` (ISO2/ISO3, default US) and the span with `?limit=` years (default 10). Cross-country macro reference. Source: World Bank (CC BY 4.0).

Profile a wallet's activity and label it smart-money (ROI, activity, token set) on Base. Returns a score + top holdings. DO NOT use to solicit investments.

Did this token's contract change under you? Compare a Base contract against Tereno's previous observation and catch a silent proxy upgrade, an admin swap, a bytecode change or a contract that just got paused: the moves that turn a token you can sell into one you cannot. Every answer names the block it stops being valid at, so a bot knows when to re-check. Priced for the moment a launch is screened by everyone at once: $0.02 if nobody has asked yet, $0.01 once another bot has.

Strip prompt-injection vectors and invisible characters from untrusted text before sending to an LLM — $0.003 USDC/call on Base. Pay-per-call via x402 — no API key, no account. Free samples daily.

A company's recent SEC disclosure picture in one call: the filings index, insider transactions from Form 4 with a net buy/sell signal, material 8-K events by item code, and initial holdings from Form 3.
