## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability blockscout-token-info-by-address-042d7180
```

Example prompt: Can you look up the token details for contract address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain ID 1) using Blockscout — I need the symbol, decimals, circulating supply, market cap, and 24h volume.

## When to prefer this

Use this endpoint when you need comprehensive token metadata and market statistics for a specific token contract address on a known blockchain network. It is ideal when you have the contract address and chain ID and want authoritative on-chain data from Blockscout's indexer rather than off-chain aggregators like CoinGecko. Prefer this over general search endpoints when you already know the exact address and just need the details.

## Known failure modes

- Invalid or non-existent contract address returns 404 or empty result
- Unsupported chain_id returns an error or no data
- Non-token contract address (e.g. a wallet or DEX contract) may return empty token fields
- Rate limiting or payment failure (x402) blocks the request
- Some fields like icon_url or exchange_rate may be null for low-liquidity or unlisted tokens

## How this service works

Explore crypto activities with Blockscout's multichain search. Find transactions, addresses, tokens, and dapps across top blockchain networks — your go-to explorer for cross-chain blockchain data

## Output

Returns a JSON object with the token's name, symbol, decimals, icon URL, reputation score, 24-hour trading volume, total supply, exchange rate, holders count, circulating supply, circulating market cap, bridge type (if bridged), foreign address, and origin chain ID — covering both metadata and live market metrics for the token contract.
