AxionQuant
Prices, filings and alternative series behind one key
What it is
A hosted REST API, with Python and JavaScript clients, for prices and reference data across several asset classes. Equity calls list tickers and OHLCV bars, and further namespaces cover statements, SEC filings, ETF holdings, forex, futures, indices, crypto, macro series, news, credit, ESG, supply-chain links, sentiment and web traffic, plus helpers that build pandas frames. Notebook users and developers who want those sets from a single key are the audience. Every call needs a vendor API key, the catalog is a remote service rather than a repository you clone, and the helpers only transform frames already downloaded.
