Financial Data x402

Live Amazon.com product page data by ASIN: title, current price, star rating, review count, availability, product images, and bullet points -- scraped directly from the public product page, not a third-party product-data API. US marketplace (amazon.com) only. Best-effort: Amazon may occasionally rate-limit or block scraping requests, which surfaces as a 502 rather than stale or fake data. $0.05/call.

Top customer reviews for an Amazon.com product by ASIN: star rating, title, body, author, date, and verified-purchase flag per review -- scraped directly from the public reviews page. US marketplace (amazon.com) only. Supports optional limit (default 10, max 25). A product with no reviews returns 200 with an empty list, not an error. Best-effort: Amazon may occasionally rate-limit, block, or gate reviews behind a login wall, which surfaces as a 502 rather than stale or fake data. $0.05/call.

Analyst sentiment and short interest for a US stock in one call: recommendation trend, consensus price targets, recent upgrades/downgrades by firm, and short interest with month-over-month change -- rising short interest into price weakness is a classic bearish/squeeze-risk signal most analyst-ratings APIs don't include. From real Yahoo Finance data. $0.005/call.

Every US airport currently under an active FAA advisory in one call: closures, ground stops, ground delay programs, and arrival/departure delays, each with its reason and timing. Live from the FAA's own public National Airspace System status feed -- the same source air traffic control uses. Not airport-specific. $0.01/call.

Nearest Ethereum block number to a given Unix timestamp, from Etherscan's V2 API -- anchors a point in time to a specific block for historical on-chain lookups (e.g. state as of a given date). Not address-specific. $0.01/call.

Basic company/fund profile for a US ticker: name, sector/industry (or fund category for ETFs), country, exchange, employee count, market cap, and a short business summary. From real Yahoo Finance data. $0.005/call.

SENATE ONLY -- does not include the US House of Representatives. Most recent US Senate stock trade disclosures for a ticker (STOCK Act periodic transaction reports), sourced from official efdsearch.senate.gov filings. Disclosures are legally allowed up to 45 days after the trade, so this is not real-time. Optional 'limit' caps results (default 10, max 25). A ticker with no disclosed Senate trades returns 200 with an empty list, not an error. $0.05/call.

Deployer address and creation transaction for a contract address, from Etherscan's V2 API -- who deployed it and when, pairs naturally with /contract-source. A non-contract or unrecorded address returns found=false rather than an error. $0.01/call.

Rolling correlation between a crypto asset's daily returns and a stock/index ticker's (default SPY) over a lookback window (default 90 days, range 14-365) -- a cross-asset signal, e.g. is ETH still trading like a risk asset correlated with QQQ. Combines CoinGecko and Yahoo Finance daily closes. $0.01/call.

Daily price/market-cap/volume history for one coin -- the crypto analogue of /history, for BTC, ETH, SOL, and 17+ other major coins by ticker. Optional 'days' controls the lookback window (default 30, max 365); CoinGecko auto-picks point granularity from 'days' (roughly hourly under 90 days, daily above). From CoinGecko. $0.01/call.

Crypto perpetual-futures leverage/squeeze-risk signal in one call: funding rate, open interest, and long/short account ratio, each with recent history and a rising/falling/flat trend -- how crowded and leveraged one side of the market has gotten, the derivatives analogue of stock short interest. Works for any OKX-listed perpetual (BTC, ETH, SOL, and more). From OKX. $0.01/call.

Global crypto market snapshot in one call: total market cap, 24h trading volume, 24h market-cap % change, BTC/ETH dominance, and active-coin/market counts -- the whole-market context behind any single coin's move. Not ticker-specific. From CoinGecko. $0.005/call.

Top crypto gainers and losers by 24h % change among the top 250 coins by market cap -- the crypto analogue of /movers, scoped to liquid, real assets rather than micro-cap noise. Supports optional limit (default 10, max 25). From CoinGecko. $0.01/call.

Price of one crypto in terms of another -- BTC/USD, ETH/BTC, SOL/ETH, or any pair from 21+ major coins by ticker. Handles crypto/crypto pairs (e.g. how many ETH is 1 BTC worth) as well as a plain USD quote. Returns each leg's own 24h % change vs USD rather than a synthetic ratio change. From CoinGecko. $0.01/call.

Top DeFi protocols by DEX trading volume, live from DeFiLlama: 24h/7d volume with % change, across ~1,300 tracked protocols. Optionally filter to one chain. Not ticker-specific. Supports optional limit (default 10, max 25). $0.01/call.

DeFi protocol TVL snapshot by exact DeFiLlama slug (e.g. 'uniswap', 'aave', 'lido'): total value locked with 1d/7d % change, market cap, and top chains by TVL -- from DeFiLlama, the standard source for cross-chain DeFi TVL data. Not a search; requires the exact slug. $0.01/call.

Dividend and corporate-action history for a US stock in one call: forward/trailing yield and payout ratio, next ex-dividend/payment date (never a stale already-elapsed date), last dividend paid, up to 12 most recent dividend payments, and stock split history. A non-payer returns clean nulls, not an error. From real Yahoo Finance data. $0.01/call.

Earnings intelligence for a US stock in one call, not just a calendar: next earnings date with EPS/revenue estimates, the last 4 quarters' actual-vs-estimate surprises, and whether Wall Street's estimates are being revised up or down over 7/30/60/90 days -- a leading sentiment signal most earnings-calendar APIs don't offer. From real Yahoo Finance data. $0.01/call.

Key US macro indicators in one call, live from FRED: Fed funds rate, unemployment rate, CPI/core CPI/PCE inflation (YoY), real GDP growth (QoQ annualized), industrial production (YoY), retail sales (MoM), and consumer sentiment -- roughly 8 separate FRED series lookups collapsed into one request, with YoY/MoM math already done. Not ticker-specific. $0.01/call.

Total ETH supply, from Etherscan's V2 API. Not address-specific. $0.01/call.

Historical OHLCV/candlestick bars for any US stock ticker over any date range — 1-minute intraday up to monthly at precise multipliers (1/2/5/15/30/60/90-minute, 1-hour, 1/5-day, 1-week, 1/3-month), from real Yahoo Finance data. Supports backtesting, charting, and multi-timeframe analysis. $0.01/call.

US housing market snapshot in one call, live from FRED: housing starts, building permits, the Case-Shiller home price index with YoY change, and the 30-year fixed mortgage rate -- replaces 4 separate FRED series lookups. Not ticker-specific. $0.01/call.

US stock technical indicators for day trading in one call: SMA/EMA(20,50), RSI(14), Stochastic(14,3,3), Bollinger Bands(20,2), MACD(12,26,9), ATR(14), ADX(14) with +DI/-DI, relative volume, price change over 1d/5d/1mo, and distance from the 52-week high/low -- for AAPL, TSLA, MSFT, or any US ticker, from real Yahoo Finance daily bars. Includes a transparent bullish/bearish/neutral signal with a per-indicator reasoning breakdown, not an opaque AI black box. $0.005/call.

Who's actually buying and selling a US stock, in one call: named insider transactions (role, buy/sell/gift/award, shares, dollar value), a 6-month insider purchase/sale summary, top institutional (13F-style) holders with % held and quarter-over-quarter change, and the full insider/institutional ownership breakdown -- cluster insider buying and institutional accumulation are among the highest-conviction signals in equity research. From real Yahoo Finance data. $0.025/call.

Recent internal transactions (value transfers triggered by a contract call -- swaps, withdrawals, contract creations) for a wallet or contract address on Ethereum, from Etherscan's V2 API. These never show up in a normal txlist but often carry the actual fund movement. Supports optional limit (default 25, max 100). $0.01/call.

US weekly jobless claims in one call, live from FRED: initial claims, continuing claims, and 4-week moving average of initial claims, with week-over-week change computed where available — a leading labor-market indicator that drives risk-off and day-trading directional calls. Replaces 3 separate FRED series lookups. Not ticker-specific. $0.01/call.

US labor market snapshot in one call, live from FRED: nonfarm payrolls (level + MoM change), JOLTS job openings, average hourly earnings (YoY), and labor force participation rate -- the monthly labor picture that complements /jobless-claims' weekly initial/continuing claims. Replaces 4 separate FRED series lookups. Not ticker-specific. $0.01/call.

FOMC meeting dates and major US economic release dates (CPI, non-farm payrolls, GDP, PCE, retail sales) in one call, each with a days-until countdown, between 'from' and 'to' -- the market-wide catalysts that move every ticker at once. FOMC dates from the Fed's official calendar; release dates live from FRED, and a temporarily-unavailable release is reported explicitly, not silently dropped. Not ticker-specific. $0.01/call.

US money supply and bank credit snapshot in one call, live from FRED: M2 money stock (level + YoY change), M1 money stock, and commercial & industrial loan volume (level + YoY change) -- liquidity/credit-conditions indicators distinct from the price-level inflation series in /economic-indicators. Replaces 3 separate FRED series lookups. Not ticker-specific. $0.01/call.

Day's biggest gainers and losers screened from the entire market, live from Yahoo Finance. Each mover includes ticker, company name, current price, intraday change amount and %, and volume — the market context every trader needs. Not ticker-specific. Supports optional limit per list (default 10, max 25). $0.01/call.

Native ETH balance for up to 20 wallet addresses in one call, from Etherscan's V2 API -- a portfolio-style batch lookup instead of N separate /wallet-balance calls. Not address-scoped in the path; pass addresses as a comma-separated query param. $0.01/call.

Latest news headlines and summaries for a stock ticker from real Yahoo Finance data. Includes article title, summary, publish date, publisher name, and URL — everything needed to monitor sentiment and catalysts. Supports optional limit parameter (default 10, max 50). $0.005/call.

Options chain with calls and puts, all strikes, implied volatility, volume, open interest, and put/call volume ratio from real Yahoo Finance data. Supports optional expiration date selection (defaults to nearest). Essential for options traders analyzing volatility skew and positioning. $0.01/call.

A full multi-outcome Polymarket event (e.g. every candidate in an election) as one ranked probability list, by exact event slug -- instead of stitching together each candidate's individual binary market via /prediction-markets search. Polymarket-only. $0.01/call.

Every open market under one exact Kalshi series ticker (e.g. Fed rate decisions, recession odds) -- the reliable, exhaustive complement to /prediction-markets' best-effort keyword scan. Unlike keyword search, series_ticker is a genuine exact server-side filter. An empty result can mean an unknown series_ticker OR a real series with nothing open right now -- Kalshi's API returns the same response for both, flagged via the 'note' field. Supports optional limit (default 25, max 50). $0.01/call.

A single prediction market's current odds, volume, and close date by exact ID -- from Polymarket (slug) or Kalshi (ticker), whichever you pass as `source`. Pairs with /prediction-markets: search there first to find an ID, then re-fetch it here for the freshest odds without re-searching. $0.01/call.

Prediction market arbitrage in one call: keyword search across Polymarket AND Kalshi simultaneously -- no other market-data API aggregates both -- returning each match's live, real-money-backed outcome probabilities, volume, and close date, so you can spot pricing gaps between the two venues on the same event. Crowd-sourced forecasts for Fed decisions, elections, and macro events often beat polls and analyst surveys; pairs naturally with this API's own FOMC/economic calendar. Not ticker-specific. $0.03/call.

US Producer Price Index (PPI) in one call, live from FRED: headline Final Demand PPI and core PPI (ex food & energy), both YoY -- a leading inflation indicator that moves ahead of the consumer-side CPI/PCE already in /economic-indicators, since producer cost changes flow through to consumer prices with a lag. Not ticker-specific. $0.01/call.

Real-time quote in one call: current price, intraday open/high/low, previous close with change and change %, volume metrics, 52-week high/low, and 50/200-day moving averages from real Yahoo Finance data. Works for stocks, forex pairs (e.g. EURUSD=X), and commodity futures (e.g. GC=F gold, CL=F oil), not just equities. $0.001/call.
