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 a results block containing: ticker symbol, company name, CIK, type (e.g. CS for common stock), active status, locale, market, headquarters address, branding icon and logo URLs, SIC code and description, listing date, round lot size, market cap, company description, ticker root, homepage URL, phone number, currency, composite FIGI, share class FIGI, total employees, weighted and share class shares outstanding, plus a request_id.
Example use cases
Enrich portfolio with company profiles
“For each ticker in my portfolio — AAPL, MSFT, and GOOGL — pull their full company profiles including market cap, SIC description, total employees, and primary exchange.”
Verify company identity before trade
“Before I place this order, can you confirm that TSLA is an active common stock trading on a US exchange and give me its CIK and composite FIGI?”
Research competitor fundamentals
“I'm analyzing the semiconductor sector — look up the reference data for NVDA, including its SIC code, market cap, employee count, and headquarters address.”
Technical details
Endpoint
GEThttps://agent.massive.com/v3/reference/tickers/%7Bticker%7DWhen to prefer
Choose this endpoint when you need authoritative, structured reference data for a single US stock ticker — including company identity, SEC CIK, SIC classification, exchange, market cap, branding, and address — without setting up an account or API key. The x402 micropayment model ($0.01 USDC per call) makes it ideal for low-volume or on-demand lookups by AI agents that need to enrich financial data pipelines or verify company identity programmatically. Prefer it over subscription-based financial data APIs when cost-per-call economics are favorable and you want no-friction access.
Side effects
- Invalid or unknown ticker symbol returns an error or empty results
- Payment settlement failure results in continued 402 response
- Delisted or inactive tickers may return stale or partial data
- Malformed ticker path parameter causes a 400 or routing error
- Network timeout during payment flow leaves request unresolved
