interval, time_start, time_endstringDefault1d, none, nowSee History: what the endpoints share

Response

Fields

Field	Type	Notes
`id`, `interval`	number, string	What you asked for
`points[].time`	string	RFC3339 UTC: the start of the hour, or midnight for a day
`points[].price`	string	USD, never `null`
`points[].market_cap`, `points[].volume_24h`	string or `null`	USD; `null` where we have a price only

Each point is the last value we recorded in its hour or day. Our older history was filled in from price records, so those points carry a price only and can be days apart; we fill in nothing between them. New points arrive every hour, and the newest ones can still be revised for a while after; today's daily point appears once the day is over.

Examples

bash

# An asset's daily prices since the start of the year
curl -H "X-Api-Key: <your-api-key>" \
  "https://open-api.coinworldcap.com/openapi/v1/rwa/history?id=90001&time_start=2026-01-01T00:00:00Z"

HTTP status	`code`	When
400	40000	`id` missing or not a positive integer; a parameter the shared history rules refuse
404	40400	No RWA we list with that `id`: it does not exist, it is a crypto asset's id, or the asset has been delisted — the same ids `/rwa/info` answers `404` for

The other errors are in Errors.
