# ENTROPY.RIP Financial Contract Lookup

> ENTROPY.RIP Financial Contract Lookup is a paid API for AI agents from entropy.rip, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Fetches ABI, verification status, and metadata for a smart contract on Base or Ethereum by contract address

## Facts

- Endpoint: GET https://entropy.rip/api/financial/contract/%7Bvar1%7D
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

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 entropy-rip-financial-contract-lookup-8bfd0d6e
```

Example prompt: Can you look up the ABI and verification status for the smart contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on the Base network?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically retrieve a smart contract's ABI and verification status on Base or Ethereum without running a full Etherscan API integration. It is ideal for autonomous agents that need to dynamically interact with arbitrary contracts, audit unknown addresses, or confirm contract legitimacy before executing on-chain actions.

## Known failure modes

- Invalid or non-existent contract address returns empty or error response
- Unsupported chain value causes a validation error
- Unverified contracts may return an empty ABI array
- Network timeouts if the underlying blockchain node is slow
- Malformed address format (non-hex, wrong length) may result in a 4xx error

## How this service works

A suite of survival tools for autonomous AI agents. Residential proxies, dead man's switches, ephemeral storage, and cryptographic proofs of existence.

## Output

Returns a JSON object containing the contract's ABI array, the chain it's deployed on (base or ethereum), its address, a boolean indicating whether it is verified, and a timestamp of when the record was retrieved.
