ELGON FAQ
Frequently asked questions about Elgon’s enriched market data API.
See our list of FAQ in our docs.
Elgon is a market-data API covering the Robinhood product surface — stocks, ETFs, options, crypto, and prediction markets. It provides delayed pricing and instrument data across every US-listed stock and ETF, full options chains, and major crypto venues, all through one low-latency API.
Most API providers just take raw market data and put an API wrapper around it. They then leave the data enrichment process up to the builders. Elgon takes this data and makes it instantly useful for a variety of different use-cases.
The Elgon API has a variety of use cases, including trading terminals, analytics platforms, brokerage apps, portfolio trackers, tax software, LLMs, social networks, and trading bots. Visit our case studies for examples of applications using Elgon.
Getting an API key is free and quick. Once you've created your key, review our documentation for instructions on how to integrate Elgon into your application.
If you still have questions, contact support for more help.
