How this service works

Financial market data — stock prices, forex, crypto, commodities, economic indicators, technical analysis, and news sentiment.

Output

Returns a JSON object containing a list of best-matching symbols with fields such as symbol, name, type (equity, ETF, etc.), region, market open/close times, timezone, currency, and a match score indicating relevance. Also includes payment metadata (settled USDC amount) and a request ID for tracking.

Example use cases

Resolve company name to ticker

“I want to buy stock in 'Science Applications International Corporation' but I don't know its ticker — can you search for 'SAIC' and tell me the exact symbol and which exchange it trades on?”

Discover all stocks matching keyword

“Search for any stocks or ETFs with 'semiconductor' in the name so I can decide which one to research further.”

Verify ticker before trading

“Before I place a trade, can you confirm the correct ticker symbol and exchange for 'Nintendo' — I want to make sure I'm looking at the right listing?”

Endpoint

When to prefer

Use this endpoint when you need to resolve a human-readable company name or partial ticker string into a valid, exchange-qualified stock symbol before querying price data or placing trades. Prefer this over hardcoding tickers when the exact symbol is uncertain, when supporting user-typed company names, or when building a search-as-you-type stock lookup. The x402 micropayment model means no API key management is needed — pay per use in USDC.

Side effects

Empty results if keywords don't match any known symbol or company
Payment failure if USDC balance is insufficient for the $0.008 per-call fee
Ambiguous results when keywords match many companies (no single best match)
Rate limiting or service unavailability from underlying Alpha Vantage API
Invalid datatype parameter value causing request rejection
