- TypeScript: <https://skmtc.dev/ankr/apis/ankr-advanced-api/docs/%3Fankr_getCurrencies/post.ts> (a function with typed inputs; its response is checked against the schema)

Returns the catalog of currencies (native coin + indexed ERC-20 tokens) for a single blockchain, including symbol, decimals, contract address, and a thumbnail URL.

Pass `blockchain` to scope the catalog. Useful for building asset pickers, populating token dropdowns, or mapping unknown contract addresses to known token metadata.

Part of the **Token API** product (700 compute units per call, $0.00007 at base rate).

  - `method` 'ankr_getCurrencies', required
  - `params` object, required
    - `blockchain` 'arbitrum' | 'avalanche' | 'base' | 'bsc' | 'eth' | 'fantom' | 'flare' | 'gnosis' | 'linea' | 'optimism' | 'polygon' | 'scroll' | 'somnia_mainnet' | 'taiko' | 'telos' | 'xlayer' | 'avalanche_fuji' | 'base_sepolia' | 'eth_sepolia' | 'optimism_sepolia' | 'polygon_amoy', required: Target blockchain identifier.

## Response `200`

- object
  - `id` integer, required
  - `jsonrpc` '2.0', required
  - `result` object, required
    - `currencies` object[], nullable, required: Indexed currencies on the chain.

## Other responses

- `400`: Bad Request — malformed JSON-RPC envelope or invalid `params`. The gateway rejects before the JSON-RPC layer processes the call.
- `401`: Unauthorized — missing or invalid API key in the server URL path. Verify that `{API_KEY}` is set to a valid project key.
- `429`: Too Many Requests — the API key has exceeded its rate or quota limits. Back off and retry; consider upgrading the Premium tier for higher limits.
- `500`: Server error — unexpected condition. Retry with exponential backoff; if it persists, file a ticket at https://www.ankr.com/support/.
