# 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 address on Base or Ethereum

## Facts

- Endpoint: GET https://entropy.rip/api/financial/contract/%7Baddress%7D
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/entropy-rip-financial-contract-lookup-e54184b7
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_OzUu4Er4ok52flFa5F4CY

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-e54184b7
```

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

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call lookup of a smart contract's ABI and verification status on Base or Ethereum without setting up your own blockchain node or indexer. It is preferable to Etherscan or similar explorers when you are operating in an autonomous agent context that supports x402 micropayments and need a simple REST interface with structured JSON output.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address not found on the specified chain returns empty or null ABI
- Unsupported chain value returns validation error
- Unverified contracts may return an empty ABI array with verified: false
- Network timeouts or upstream blockchain node failures may cause delayed or failed responses

## 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 blockchain network it was found on (base or ethereum), the contract address, a boolean indicating whether it is verified, and a timestamp of when the data was recorded.
