## 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 apexapi-crypto-contract-read-a401a579 -d '<json body>'
```

Example prompt: Can you read the current state of the USDC contract on Ethereum — I want to know things like total supply or the owner address stored on-chain?

## When to prefer this

Use this endpoint when you need to read on-chain smart contract data without setting up your own RPC node or managing API keys; ideal for agents needing quick, pay-per-call access to blockchain contract state.

## Known failure modes

- Invalid contract address returns error or empty result
- Unsupported blockchain network returns an error
- Malformed query string causes parsing failure
- Contract function does not exist returns revert or null
- Network timeout or RPC failure returns 500 error
- Insufficient USDC payment (x402) blocks the request

## 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 the on-chain data from the specified smart contract, such as stored variable values, function return values, or contract state — depending on the query submitted.
