Changelog

Changes to the CoinWorldCap API, newest first. Additions — new endpoints, fields and accepted values — ship without a version bump, which is why Before you integrate asks your client to ignore what it does not recognise; a breaking change comes with notice and an overlap period.

2026-11-05

New endpoints:

• Real-world assets: /rwa, /rwa/info and /rwa/issuers.
• Earn yields for a coin across platforms: /earn.
• History, daily or hourly: an RWA's price, market cap and volume, /rwa/history; a coin's funding rate, open interest and basis, /derivatives/history; a chain's market cap and volume, /chains/history. And daily: a coin's earn APYs by product, /earn/history.
• Derivatives: perpetual and futures contracts by coin or exchange, /derivatives/pairs, and the exchanges' totals, /derivatives/exchanges.
• The teams behind projects: /assets/team, /exchanges/team, /people and /people/info.
• DEX tokens: /dex/chains, /dex/tokens, /dex/search, /dex/tokens/info, /dex/tokens/trades, /dex/tokens/liquidity, /dex/tokens/holders, /dex/tokens/pools and /dex/tokens/history.
• Your key's plan and usage: /key/info.

Changes to existing endpoints:

• /assets looks assets up by contract address (chain_id with contract_address), and fields=platforms lists every chain an asset is deployed on.
• /quotes and /trending rows carry volume_24h, the same value as volume under the name the other endpoints use.
• /quotes and /assets take select, which returns only the row fields you name — as do the new /rwa and /dex/tokens. See Choosing fields with select.
• Two parameters that used to be ignored are now checked. On /quotes and /assets, a select name that is not one of the row fields is a 400. On /assets, chain_id and contract_address go together: either one alone is a 400. Before this release both were ignored, as any parameter an endpoint does not read.
• /chains' logo falls back to the chain's own logo when its native coin has none.
• A 404 with code 40400 is no longer /global's alone: an endpoint that returns one resource answers it when that resource does not exist. See Errors.
• This documentation moved off the API host to a site of its own. The old addresses under /docs on the API host redirect to the same page here.

• /exchanges lists centralized exchanges only. A decentralized exchange's id or slug matches nothing, and total does not count them.

• First release: /assets, /quotes, /trending, /exchanges, /global, /categories and /chains, authenticated with X-Api-Key and rate limited per account.
