Account Center › API Reference › Asset Catalog

Allowed assets, precision, and machine-readable network codes for each chain

GET /v1/assets scope: merchant:read

Merchant account

Fetch and cache this catalog first when integrating: the scaling precision for every subsequent amount field comes from its ledger_scale. New assets are added through administration without a release, so do not hardcode the catalog.

Merchants without an asset allowlist see all enabled assets. The allowlist restricts rather than enables: no rows means no restriction.

⚠ The top-level key is assets, not data, for legacy reasons. This endpoint has no pagination envelope.

ledger_scale cannot change after listing, so it may be cached long-term. display_scale only controls displayed digits; never use it to parse amounts.

Parameters

This endpoint takes no parameters: no path parameters, query parameters or request body. For the authentication header (x-auth-token) and on-behalf-of header (x-on-behalf-of), see Authentication and Signing.

Additional Details

networks[]: do not submit display names as parameters

The network parameter in POST /v1/withdraw-addresses and POST /v1/merchant/deposit-addresses accepts a machine-readable code (BSC). It is case-sensitive; unrecognized values immediately return asset_not_allowed. This catalog is its sole authoritative list.

Field	Meaning	Valid as an input parameter?
`network`	Machine-readable code, such as `BSC`	✅ Use this
`network_name`	Display name, such as `BNB Smart Chain (BEP20)`	❌ Always rejected

⚠ Unavailable networks are still listed, with deposit_enabled / withdraw_enabled and their respective *_unavailable_reason. Omitting them would make you think your input was wrong.

Withdrawal fields min_withdraw / max_withdraw / withdraw_fee_* / withdraw_cooling_hours reflect what we charge end users and can be used directly to calculate the received amount. Charging a separately invented value will never reconcile with our ledger.
