x402
Task Radar ABI Lookup (Sourcify) is a paid API for AI agents from task-radar-x402.vercel.app, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-31).

How this service works
Verified contract ABI + compiler/verification status (Sourcify). Chains: ethereum, base, arbitrum, optimism, polygon, bsc. 0.02 USDC/call on Base.
Output
Returns the full verified contract ABI (as a JSON array of function/event/error descriptors), along with compiler version, language, verification status (e.g. fully verified, partially verified), and Sourcify metadata for the requested contract address on the specified chain.
Example use cases
Interact with a DeFi contract programmatically
“Get me the full verified ABI for the Uniswap V3 router at 0xE592427A0AEce92De3Edee1F18E0157C05861564 on Ethereum so I can call its swap functions.”
Verify contract source before investing
“Is the contract at 0x4200000000000000000000000000000000000006 on Base actually verified on Sourcify? Show me its compiler info and ABI.”
Decode contract interface on Arbitrum
“I need the ABI for the contract 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum — can you pull it from Sourcify and tell me what functions it exposes?”
Technical details
Endpoint
GEThttps://task-radar-x402.vercel.app/api/abi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the verified ABI or compiler metadata for a smart contract and want Sourcify-backed verification status rather than Etherscan. Preferred when working across multiple chains (Base, Arbitrum, Optimism, Polygon, BSC) with a single unified API and x402 micropayment access. Choose this over Etherscan-based alternatives when you care about open, decentralized verification provenance via Sourcify.
Side effects
- Contract not verified on Sourcify — returns unverified or 404 status
- Invalid contract address format — request fails with validation error
- Unsupported chain specified — returns error indicating valid chain options
- Contract exists on-chain but was never submitted to Sourcify — no ABI available
- Network timeout fetching from Sourcify upstream
