# DDG Contract ABI Lookup

> DDG Contract ABI Lookup is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Retrieves a smart contract ABI artifact for a specified contract, payable via x402 multi-chain USDC microtransaction

## Facts

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 ddg-contract-abi-lookup-07cbdb50 -d '<json body>'
```

Example prompt: Can you fetch the contract ABI for the Uniswap v3 pool contract at 0x8ad599c3A0ff1De082011EFDDc58f1908eb6e6D8 on Ethereum mainnet so I can decode its function calls?

## When to prefer this

Choose this endpoint when you need a bounded, pay-per-use ABI retrieval without provisioning a raw provider account (e.g. Etherscan API key). Ideal for AI agents operating autonomously with x402 USDC micropayment rails that need on-demand smart contract interface data at $0.002 per call. Prefer over free alternatives when programmatic, machine-payable access with no key management is required.

## Known failure modes

- Unknown or unrecognized contract address returns an error or empty ABI
- Payment not settled via x402 results in 402 Payment Required response
- Unsupported blockchain network returns an error
- Malformed POST body (missing required fields) results in 400 Bad Request
- Contract ABI not indexed by DDG results in a not-found error

## Output

Returns a JSON response with an 'ok' boolean and the requested contract ABI artifact — the structured definition of the smart contract's functions, events, and types needed for programmatic interaction.
