Access to each data domain is controlled by a feature on your subscription plan. Your API key inherits your account’s plan, and entitlement is resolved live on every request — so plan changes take effect immediately, with no need to rotate your key.

​
Feature codes

Each domain maps to one feature code:
DomainFeature codeWeight per call
Commoditiescommodities_data3
Cryptocrypto_data3
ETFetf_data8
FXfx_data3 – 6
Macromacro_data2
Real Estaterealestate_data2

​
When a feature isn’t in your plan

Calling a domain your plan doesn’t include returns HTTP 403: 
{
  "success": false,
  "statusCode": 403,
  "error": { "code": "FEATURE_NOT_IN_PLAN", "message": "Your plan does not include this feature" },
  "meta": { "timestamp": "2026-06-19T08:34:08.100Z" }
}
To unlock the domain, upgrade your plan from the dashboard.
The exact mapping of plans (and their per-minute quota) to features is managed in the dashboard and may change as new tiers are introduced. This page lists the feature codes; your account page shows the features and quota active on your current plan.

​
How entitlement is resolved

  1. Your X-API-Key identifies your account.
  2. The account’s effective plan is looked up.
  3. The plan’s active features determine which domains you may call, and its weight budget determines your rate limit.
Because this happens per request, upgrading or downgrading is reflected instantly.
