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 containing the ticker symbol, an array of aggregate bar objects (each with open, high, low, close, volume, volume-weighted average price, number of transactions, and a millisecond timestamp), adjusted flag, result count, query count, request ID, and an optional next_url for cursor-based pagination.
Example use cases
Backtesting a momentum strategy
“Get me daily OHLCV bars for NVDA from 2023-01-01 to 2023-12-31, sorted ascending, adjusted for splits — I'm building a momentum backtest and need the full year of candles.”
Intraday price chart for a trading dashboard
“Fetch 5-minute aggregate bars for SPY on 2024-11-15 — give me the open, high, low, close, and volume for every 5-minute window that day, sorted ascending.”
Quarterly earnings price-move analysis
“Pull weekly adjusted bars for TSLA from 2024-07-01 to 2024-09-30 so I can see how the stock moved quarter over quarter leading into earnings.”

Endpoint
GEThttps://agent.massive.com/v2/aggs/ticker/%7BstocksTicker%7D/range/%7Bmultiplier%7D/%7Btimespan%7D/%7Bfrom%7D/%7Bto%7DWhen to prefer
Choose this endpoint when you need historical or recent US stock OHLCV aggregate bars at any granularity (minute through year) without setting up an account or subscription — payment is per-request via x402 USDC micropayment. Prefer this over subscription-based data APIs when running ad-hoc or low-frequency queries where paying per call is more economical than a monthly plan.
Side effects
- 402 Payment Required returned when x402 payment has not yet settled — normal flow, agent must complete payment before data is returned
- Invalid ticker symbol returns an empty results array or error status
- Date range produces no results if market was closed or range is invalid
- Malformed date format (not YYYY-MM-DD or millisecond timestamp) causes a 400 error
- Limit exceeding 50000 is rejected
- Network timeout if payment settlement is slow
