The Tokens API provides metadata and realtime pricing information for native and ERC20 tokens on supported EVM blockchains. The API returns:

• Token metadata (symbol, name, decimals)
• Current USD pricing information
• Supply information
• Logo URLs when available

The ?chain_ids query parameter is mandatory. To learn more about this query parameter, see the Supported Chains page.

Native vs. ERC20 tokens

The address path parameter can be set to native for chain-native assets or to an ERC20 contract address. Include the required ?chain_ids query parameter to select the chain. The response shape differs slightly for native assets vs ERC20 tokens.

Native asset

Use native as the address path parameter.

Native Request Example

GET /v1/evm/token-info/native?chain_ids=1

Native Response Example

{
  "contract_address": "native",
  "tokens": [
    {
      "chain_id": 1,
      "chain": "ethereum",
      "price_usd": 3900.777068,
      "symbol": "ETH",
      "name": "Ethereum",
      "decimals": 18,
      "logo": "https://api.sim.dune.com/beta/token/logo/1"
    }
  ]
}

ERC20 token

Use the token’s contract address as the address path parameter. Additional fields like pool_size, total_supply, and fully_diluted_value may be present.

ERC20 Request Example

GET /v1/evm/token-info/0xd9aaec86b65d86f6a7b5b1b0c42ffa531710b6ca?chain_ids=8453

ERC20 Response Example

    }

Token Prices

Sim looks up prices onchain. We use the most liquid onchain pair to determine a usd price. We return the available liquidity in pool_size as part of the response.

Historical prices

You can request historical point-in-time prices by adding the optional historical_prices query parameter. Use whole numbers to specify the number of hours in the past. You can request up to three offsets. For example, historical_prices=8760 returns the price 8760 hours (approximately 1 year) ago. historical_prices=720,168,24 returns prices 720 hours (1 month) ago, 168 hours (1 week) ago, and 24 hours ago.

The historical_prices query parameter is currently supported only on the EVM Token Info and EVM Balances endpoints.

When set, each token object includes a historical_prices array with one entry per offset:

{
  "tokens": [
    {
      "chain": "base",
      "symbol": "ETH",
      "price_usd": 3897.492219,
      "historical_prices": [
        { "offset_hours": 8760, "price_usd": 2816.557286 },
        { "offset_hours": 720,  "price_usd": 3714.205613 },
        { "offset_hours": 168,  "price_usd": 3798.926195 }
      ]
    }
  ]
}

Percent changes are not returned. You can compute your own percentage differences using the current price_usd and the values in historical_prices[].price_usd.

Pagination

This endpoint uses cursor-based pagination. You can use the limit parameter to define the maximum page size. Results might at times be less than the maximum page size. The next_offset value is included in the initial response and can be utilized to fetch the next page of results by passing it as the offset query parameter in the next request.

You can only use the value from next_offset to set the offset parameter of the next page of results. Using your own offset value will not have any effect.

Compute Unit Cost

The Token Info endpoint has a fixed CU cost of 2 per request. The chain_ids query parameter is required but does not change the CU cost. See the Compute Units page for detailed information.
