Why Teams Choose Elgon

See how Elgon compares to Twelve Data across coverage, pricing, rate limits, and verifiable market data.

Delayed market data, clearly labelled

Get real, delayed quotes and instrument reference data for US-listed stocks and ETFs — honestly labelled as delayed, never passed off as real-time.

One API for every asset class

US-listed stocks and ETFs with real (delayed) data, plus options chains and Kalshi-style prediction (event) contracts served as clearly labelled simulated sandbox data — all through a single REST API. Elgon is an independent project, not affiliated with Robinhood.

Built to scale

Handle production traffic over simple REST endpoints. Rate limits are keyed to your plan — 60 requests/min on Free, 600 requests/min on Growth, custom for Enterprise — not a token balance.

Verifiable data you can trust

Every response ships with a signed, timestamped, tamper-evident data receipt you can verify yourself.

Elgon vs Twelve Data FAQ

Frequently asked questions about Elgon’s market-data API.

See our full list of FAQ in our docs.

Twelve Data is a solid market-data provider, and one of Elgon's closest alternatives. Where Elgon stands out is simplicity and verifiability:

  • One REST API for stocks and ETFs (real, delayed data), plus sandbox-labelled options and prediction data
  • Honest data: quotes are delayed and clearly labelled as such
  • Simple rate limits: 60 requests/min on Free, 600 requests/min on Growth
  • Signed, timestamped, tamper-evident data receipts you can verify yourself

Rate limits are keyed to your API plan and key, never to a token balance.

Yes. Elgon offers a simple REST API — six GET endpoints — with comprehensive documentation and a free API key you can mint in seconds, so migration is straightforward.

Consolidating quotes and instrument reference data behind one API often simplifies your architecture.

Creating an API key is free and quick. Once you have your key, review our documentation for instructions on integrating Elgon into your application.

If you still have questions, contact support for more help.

You can use the Elgon API to build trading dashboards, analytics tools, options-flow explorers, prediction-market prototypes, and trading bots — anything that can poll a REST endpoint. See the docs for integration examples.

Elgon has three plans: Free ($0), Growth at $350/month billed via Stripe, and custom Enterprise plans.

If Growth doesn't fit your needs, Elgon will work with you on a custom Enterprise plan.

Check our pricing table for more details.

Every REST GET call to the API counts as a request. Elgon does not offer WebSockets or webhooks — you poll the endpoints you need.

Rate limits are 60 requests/minute on Free and 600 requests/minute on Growth; Enterprise limits are custom.

If you need more, contact us to discuss more.

Yes! Start free with 10,000 API requests per month. No credit card required. Upgrade when you're ready to scale.

Elgon covers US-listed stocks and ETFs with real (delayed) data, plus options chains and Kalshi-style prediction (event) contracts served as clearly labelled simulated sandbox data. Elgon is an independent project, not affiliated with Robinhood. See the docs for the current list.
