Pricing

No. The API key is issued when the account is created and it opens four data families: price and volume, derivatives, indicators, macro. No payment method is asked for as long as you stay on that tier.

The following calls receive a 429 whose JSON body explains the reason (detail) and carries retry_after, mirrored by the Retry-After header: one second on a rate-limit overrun, one hour on an exhausted monthly quota. Nothing is billed without your knowledge, and the monthly counter restarts on the first day of the month, in UTC. The console warns you at 80% of the quota, then on the first refused request.

Yes, in both directions and at any time. The change takes effect immediately and the difference is prorated over the remaining days.

No. Each plan opens a set of data families: four on Free, seven on Traders, all twelve on Financial and Startup. The volume, the rate limit, the depth of history and the WebSocket stream follow the same progression. Raw ticks, for instance, go back one hour on Financial and one day on Startup. A family missing from your plan is missing on every channel (REST, snapshot and WebSocket), and the MCP server applies your key’s rights to every tool call.

It depends on the plan and the timeframe: it is a rolling window from now, not a per-request cap. A request that reaches further back receives an explicit 403 stating the maximum limit to use, never a silently truncated response. The full table is in the limits documentation.

From the console, in one action. The subscription stays active until the end of the period already paid for, then the account drops back to the free tier without any of your API keys being destroyed.

From Startup upwards, yes, within your own product. Beyond that (white-label resale, raw redistribution, higher volumes), the enterprise contract applies.
