Getting started with Elgon used to mean picking a plan before you had written a line of code. Not anymore. Today Elgon has self-serve API keys and pricing you can read in one breath: a free tier you can start on in a single request, one flat monthly plan when you outgrow it, and custom terms for large deployments. No sales call to try it, and no metered per-request bill to reconcile at the end of the month.
Here is exactly how billing works now, and how to get a key in the next minute.
The pricing, in plain terms
Three tiers, no asterisks:
That is the whole menu. There is no pay-per-request meter, no monthly minimum to hit, and no per-seat pricing. You either use the free tier, subscribe to Growth for a flat $350/month through Stripe, or arrange custom terms for Enterprise. See the full breakdown on the pricing page.
Get a free key in one request
The free tier is genuinely self-serve. Mint a key with a single POST — no signup form, no credit card:
curl -X POST "https://elgonrpc.xyz/api/keys"
The response returns your key once — store it immediately:
{
"key": "elgon_live_9f2c8a1e4d7b0c6a5e31b8d204f6a7c1",
"plan": "free",
"limit": "60 requests/min"
}
Prefer a UI? You can mint and manage keys from the dashboard. And if you just want to prototype, every endpoint accepts the shared public sandbox key elgon_sandbox_pub with no signup at all.
What your key unlocks
One key gives you the whole REST surface. Every endpoint is a plain GET that returns JSON with permissive CORS, so you can call it from a server, a script, or the browser:
curl "https://elgonrpc.xyz/api/v1/quotes?symbols=AAPL,MSFT&key=elgon_sandbox_pub"
The endpoints:
/quotes — last price, bid, ask, change, and volume for one or many symbols. Real market data, delayed (tagged "source":"live").
/instruments — resolve a search term to symbols and reference data. Real, delayed.
/options — options chains. Simulated sandbox data (tagged "source":"sandbox").
/predictions — prediction-market snapshots. Simulated sandbox data.
/ping — health check.
/verify — verify the signed receipt returned with every response.
What we are not claiming
Honest billing deserves honest product claims, so to be clear about what this launch is and is not:
Quotes and instruments are real but delayed, not real-time. They are perfect for dashboards, screeners, and watch-and-alert bots; they are not a low-latency execution feed.
Options and predictions are simulated sample data, labelled sandbox in every response. Build against them freely, but do not trade or report on them as real.
There is no WebSocket, no webhook, no GraphQL, no MCP server, and no per-request metering. Elgon is six REST GET endpoints plus a key-minting endpoint. Billing is a flat monthly plan, not a usage meter.
When to move to Growth
The free tier's 60 requests per minute covers most prototypes and single-symbol watchers comfortably. Move to Growth ($350/month, 600 requests/min via Stripe) when you are polling many symbols, running several services against Elgon, or need the extra headroom in production. Enterprise adds custom limits and terms. You can start free and upgrade whenever you hit the ceiling — no migration, same key model.
