How this service works
US stock market data, sold per request over x402. Every path here answers 402 with the payment terms in the PAYMENT-REQUIRED header, and answers with the data once the payment settles. No account, no API key, no subscription.
Output
A JSON object with status 'OK' and an array of ticker snapshots, each containing: intraday OHLCV bar (open, high, low, close, volume, dollar volume, VWAP), latest minute bar with timestamp, previous day OHLC and VWAP, last quote (bid/ask prices and sizes), last trade (price, size, exchange, conditions), today's absolute change, and today's percentage change.
Example use cases
Real-time top gainers dashboard
“Show me the top gaining US stocks right now with their current price, volume, and how much they've moved today — I want a live snapshot for my trading dashboard.”
Market losers alert for risk monitoring
“Pull the latest snapshot of the biggest losing US stocks today — I need ticker, price change percentage, and volume so I can flag unusual moves for our risk team.”
Pre-market movers briefing
“Give me a quick rundown of which US stocks are up the most so far today, including their last trade price and today's percentage change — I'm putting together a morning market brief.”
Technical details
Endpoint
GEThttps://agent.massive.com/v2/snapshot/locale/us/markets/stocks/%7Bdirection%7DWhen to prefer
Choose this endpoint when you need live US stock market snapshot data (gainers or losers) without committing to a subscription or managing API keys — ideal for pay-per-use agent workflows, one-off queries, or low-frequency polling where a $0.01/call micropayment model is more cost-effective than a monthly plan. Prefer it when your agent already supports the x402 payment protocol and you need structured OHLCV, quote, trade, and change data in a single call.
Side effects
- 402 Payment Required — returned when no valid x402 payment header is supplied; response includes payment terms in PAYMENT-REQUIRED header
- Invalid direction parameter — unsupported path segment returns error or empty result
- Payment settlement failure — if USDC payment does not settle, data is not returned
- Rate or network timeout — real-time data endpoint may time out under high load
- Empty tickers array — returned if no stocks match the direction filter at the requested moment
