Verifies and performs security analysis on smart contracts deployed on Ethereum, Base, BSC, Arbitrum, and Polygon

## Facts

- Endpoint: GET https://contract.lonestaroracle.xyz/verify
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_muqd1Jah8evx4ZL_5tzRP

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 contract-lonestaroracle-xyz-303e96da
```

Example prompt: Can you verify and run a security analysis on the smart contract at address 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 on Ethereum mainnet and tell me if there are any known vulnerabilities or red flags?

## When to prefer this

Use this endpoint when you need to verify smart contract source code authenticity or perform a security scan on a contract deployed on Ethereum, Base, BSC, Arbitrum, or Polygon. Prefer this over generic blockchain explorers when you need a combined verification and security analysis in a single call with structured output.

## Known failure modes

- Invalid or unrecognized contract address returns an error
- Unsupported blockchain network returns an error
- Unverified contract with no available source code may return limited results
- Rate limiting or payment failure returns 402 or 429
- Network RPC issues may cause timeouts for specific chains

## How this service works

Smart contract verification and security analysis on Ethereum Base BSC Arbitrum Polygon

## Output

Returns a verification status and security analysis report for the queried smart contract, including findings on potential vulnerabilities, code quality issues, and whether the contract source code is verified on the specified chain (Ethereum, Base, BSC, Arbitrum, or Polygon).
