How this service works
Currency list from Coinbase's public v2 API: currency code, name and minimum size, optionally filtered by a name or code fragment. Reference data only; no prices.
Output
A JSON object containing the total number of Coinbase currencies, how many matched the search filter, the timestamp of the check, the upstream source URL, and an array of matched currency objects each with a code, name, and minimum transaction size.
Example use cases
Check if asset is Coinbase-listed
“Is 'AUD' (Australian Dollar) actually supported on Coinbase? Can you look it up and tell me the minimum size?”
Browse all Coinbase fiat currencies
“Give me the first 100 currencies available on Coinbase so I can see the full list.”
Search Coinbase assets by keyword
“Search the Coinbase currencies list for anything matching 'bitcoin' and show me all the results.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/coinbase-assets?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an authoritative, up-to-date list of assets or currencies supported by Coinbase — especially when you want to validate whether a specific currency code or name is listed, find minimum trade sizes, or enumerate all available assets without requiring an API key or signup. Prefer it over generic crypto data APIs when Coinbase-specific support status is what matters.
Side effects
- limit parameter out of range (must be 1-100) may return an error or default
- search term with no matches returns an empty currencies array with matched=0
- payment failure (x402) means the call is not charged but no data is returned
- upstream Coinbase API outage could cause stale or failed responses
