## 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 nexusapi-crypto-contract-read-f52f64bd -d '<json body>'
```

Example prompt: Can you read the current owner and total supply from this Ethereum smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48?

## When to prefer this

Use this endpoint when you need to inspect the current state of a deployed smart contract without executing a transaction — e.g. checking balances, ownership, configuration parameters, or calling view functions. Prefer this over transaction endpoints when no state change is needed. Prefer this over block explorer scraping when you need structured, machine-readable output.

## Known failure modes

- Invalid contract address returns an error or empty response
- Contract not deployed on the target network returns a revert or null
- Unsupported query format results in a parsing error
- Network congestion may cause timeout or delayed response
- Querying a write function (non-view) as a read may fail or return nothing

## How this service works

Crypto, AI, Social Media, Finance, Weather, Tools &amp; more. Pay per call in USDC on Base. No API keys.

## Output

Returns on-chain data from the queried smart contract, such as state variables, mapping values, or the result of a read-only (view/pure) function call — typically including the raw return value and any decoded output fields.
