Elke response is een object met data en meta. Het meta-blok bevat het aantal rijen, de serveertijd, de disclaimer en de volledige attributiestring — reproduceer de attributie overal waar je de cijfers reproduceert.

{
  "data": [ ... ],
  "meta": {
    "count": 200,
    "served_from": "site cache — no upstream call was made for this request",
    "as_of": "2026-01-01T00:00:00+00:00",
    "disclaimer": "Research and information only — not investment advice ...",
    "attribution": "Market data and asset profiles by CoinGecko. Protocol fees ..."

Gebruiksvoorwaarden

The interface is open and unauthenticated. Please keep request rates reasonable — everything is cached for two minutes, so polling faster than that returns the same bytes. Attribute figures to the provider named in the meta.attribution string, keep the reference period with any figure you republish, and do not present these values as live prices. Redistributing the underlying data as a substitute product is not permitted; see the Terms of Use.
