# EVM Contract Pause Status Checker

> EVM Contract Pause Status Checker is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-01).

Checks whether a Pausable smart contract on a supported EVM chain is currently in a paused state

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 evm-contract-pause-status-checker-39cd36a6 -d '<json body>'
```

Example prompt: Is the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 currently paused on Ethereum?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call check of a Pausable contract's paused state across any of ten major EVM chains without running your own RPC infrastructure. It is ideal for agents doing pre-transaction safety checks, monitoring workflows, or security audits where you need instant on-chain state without managing wallet connections or RPC endpoints. Prefer this over direct RPC calls when you lack chain-specific infrastructure or need a receipted, auditable result.

## Known failure modes

- Invalid contract address format (not a valid 0x hex address) — returns validation error
- Unsupported chain name — must be one of the ten enumerated chains
- Contract at the given address does not implement the Pausable interface — may return error or false
- Network connectivity issues to the target chain RPC — timeout or RPC error
- Payment failure via x402 protocol — call not executed if payment not confirmed

## How this service works

Is a Pausable contract currently paused — Genesis402 / UnyKorn Operator Network

## Output

Returns a JSON object with an 'ok' boolean, a type field ('contract-paused'), a receipt object containing the transaction hash, USD amount charged, and a receipt ID, plus an ISO8601 timestamp indicating when the result was generated. The core answer is whether the contract is paused.
