Returns a ranked list of GitHub repos with anomalous star velocity (stars/day, fork ratio) plus an overall trend score — spot repos going viral before they hit mainstream feeds.

Find tickers by free-text `?search=` (name or symbol) across asset classes via `?market=stocks|crypto|fx|indices` (default stocks), with optional `?type=`, `?exchange=`, `?active=`, `?limit=`. Returns symbol, name, market, exchange, type, and identifiers. Use to discover crypto pairs (X:BTCUSD), FX pairs (C:EURUSD), and index symbols (I:SPX). From x402stock

Live state of every perpetual-futures market in one call: per coin the mark and oracle price, hourly funding rate with annualized APR, premium, open interest, max leverage, previous-day price, and 24h USD and base volume. Native crypto-derivatives data — funding and open interest are perp-only, absent from any spot feed. Free on-chain DEX data (venue: Hyperliquid), no key. From x402stock

Use for one call answering 'where is retail attention right now': a deterministic 0–100 attention score per ticker blending Reddit finance-community and 4chan /biz/ mention shares (24h window), with momentum, cross-platform confirmation, breadth & concentration (HHI), and Fear & Greed context. Transparent — every row carries its raw per-platform inputs. From x402stock

Reads a vesting plan/stream directly from an on-chain contract on Base — total amount, claimed/unclaimed balance, remaining lockup, current owner/recipient. A direct contract read instead of a dashboard's cached view: the vesting math is verified against the contract on every call, not assumed from an indexer. Two providers, selected by the required provider query parameter: hedgey (TokenVestingPlans) or sablier (SablierLockup, V2/v4). provider is REQUIRED — plan_id/stream_id numbering overlaps between the two contracts (e.g. id 2 is a real, distinct plan on both at once), so there is no safe default or auto-detection; a missing or invalid provider returns 400, never a guess.

Transaction fund-flow tracing with ML-powered anomaly detection across 8 live chains (Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana; BNB Smart Chain on Enterprise rollout). Returns multi-hop graph, counterparties, and risk classification.

The Crypto Fear & Greed index (0–100) with its rating, alongside the US stock Fear & Greed score for comparison, current BTC and ETH prices with 24h change, and ~90 days of crypto sentiment history. Pass `?days=N` to size the history. The crypto-sentiment companion to /api/v1/fear-greed (stocks). From x402stock, a market & economic data API (x402, USDC).

USD Coin

Use to see where prediction-market money is flowing: the most recently traded Polymarket outcome tokens with implied probability (last on-chain price), today's VWAP and USD volume, and indexed totals — decoded by our own indexer from CTF Exchange V2 events on the public Polygon ledger, not from any Polymarket API. `?limit=` up to 100. From x402stock, a market & economic data API (x402, USDC).

Compare 2 to 3 US-listed stocks side by side (peer or watchlist comparisons). Pass a comma-separated list via `?tickers=AAPL,MSFT,NVDA` (1 to 3 symbols). Returns price and day change, market cap, P/E, EPS, revenue, gross and net margins, and dividend yield per ticker. Built for multiple stocks — for a single stock, `/api/v1/quote/{ticker}` is cheaper. From x402stock

Predicted next-period funding rate for each coin across venues — on-chain plus centralized perp venues (Hyperliquid, Binance, Bybit) — each with the funding interval and next funding time. A cross-exchange funding-arbitrage signal in one call: compare where a coin's funding is richest or cheapest. Free on-chain DEX data, no key. From x402stock, a market & economic data API (x402, USDC).

Live on-chain spot prices for every token on the Hyperliquid DEX (HYPE, PURR, and hundreds more), quoted in USDC: mid/mark price, previous-day price, 24h USD and base volume, circulating and total supply, and market cap — sorted by 24h volume. Spot, not derivatives: for funding/open interest use /api/v1/perps; for major-coin fiat prices use /api/v1/crypto. From x402stock

Official US Treasury reporting rates of exchange — government FX reference rates for ~170 currencies, in units of foreign currency per 1 USD, for the latest quarter. Use for accounting-grade and exotic-currency conversion the market /api/v1/forex feed lacks. Filter with `?currency=Euro`. Updated quarterly. From the US Treasury (FiscalData). From x402stock

Conversation Risk Intelligence API for AI agents. Call BS Man API analyzes chats, offers, and proposed agent actions for scam signals, manipulation tactics, unsafe payment requests, wallet/payment risk, and risky next steps.

USD Coin

Jupiter's JLP liquidity pool, decoded from the Perpetuals program's on-chain accounts (not the Jupiter API): AUM (USD), JLP supply and virtual price (AUM ÷ supply), pool-wide long/short trader exposure, and each asset (SOL, ETH, WBTC, USDC, USDT) with holdings, owned/locked, utilization %, and long/short USD. Keyless public-chain data, no Jupiter API. From x402stock

USD Coin

Live ANM monetary state from the Animica L1 itself: supply and account count, the block reward the node will actually credit (not the published split, which is wrong by 2x), measured blocks per day, daily emission in ANM and as a percent of supply, network hashrate, and — when the ANM book is fresh — total network-wide mining revenue in USD per day. Buy before holding, quoting or mining ANM. Deterministic, no model. Charges nothing when the chain cannot be read.

US consumer price inflation from the Bureau of Labor Statistics: the latest headline CPI-U and core (ex food and energy) index levels with year-over-year percent change, plus recent monthly history. No ticker needed. Use for macro-aware analysis without leaving for a separate data source. Sourced from US BLS. From x402stock, a market & economic data API (x402, USDC).

What stocks and crypto Reddit is talking about most over the last 24h, by mention volume across the busiest Reddit money subreddits (r/wallstreetbets, r/stocks, r/CryptoCurrency, r/Bitcoin, etc.). Each ticker carries mentions, upvotes, and 24h change in rank and mentions; covered subreddits are listed per response. ?filter=stocks|crypto|all (default all), ?page=. From x402stock

Cheap poll: has the spending authority over this Safe changed since you last looked? You pass the fingerprint this route gave you last time; it recomputes the current one and compares. Call it with no fingerprint to get a baseline. The fingerprint covers owners, threshold, guard, moduleGuard, the singleton implementation, and the whole module graph including the owners and threshold of modules that are themselves Safes -- a change one level down flips it, which a flat owner list would miss. It deliberately excludes the nonce, so ordinary transactions do not read as an authority change. Nothing is stored on our side: you hold the baseline, so there is no account and no subscription. No archive reads either, which is why this is cheap; when it reports changed, buy GET /safe-signer-drift for what changed and in which block. A truncated walk returns indeterminate, never unchanged. Required: chain_id and address. Optional: fingerprint.
